Why do airlines charge so much for checked bags? This obscure rule helps explain why

<a href="https://theconversation.com/profiles/jay-l-zagorsky-152952">Jay L. Zagorsky</a>, <a href="https://theconversation.com/institutions/boston-university-898">Boston University</a> Five out of the six <a href="https://www.oag.com/blog/biggest-airlines-in-the-us">biggest U.S. airlines</a> have <a href="https://www.cnbc.com/2024/03/05/delta-is-the-latest-airline-to-raise-its-checked-bag-fee.html">raised their checked bag fees</a> since January 2024. Take American Airlines. In 2023, it cost US$30 to check a standard bag in with the airline; <a href="https://www.usatoday.com/story/travel/airline-news/2024/02/20/american-airlines-bag-fees-mileage-earning/72669245007/">today, as of March 2024, it costs $40</a> at a U.S. airport – a whopping 33% increase. As a <a href="https://www.bu.edu/questrom/">business school</a> <a href="https://www.bu.edu/questrom/profile/jay-zagorsky/">professor who studies travel</a>, I’m often asked why airlines alienate their customers with baggage fees instead of bundling all charges together. <a href="https://www.vox.com/2015/4/16/8431465/airlines-carry-on-bags">There are</a> <a href="https://www.usatoday.com/story/travel/columnist/2023/06/21/bag-fees-will-stay-a-while-cruising-altitude/70338849007/">many reasons</a>, but an important, often overlooked cause is buried in the U.S. tax code. <h2>A tax-law loophole</h2> Airlines pay the federal government <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D">7.5% of the ticket price</a> when <a href="https://www.pwc.com/us/en/services/tax/library/aircraft-club-nov-2023-air-transport-excise-tax-rates-for-2024.html">flying people domestically, alongside other fees</a>. The airlines dislike these charges, with their <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation/">trade association arguing</a> that they boost the cost to the consumer of a typical air ticket by around one-fifth. However, the U.S. Code of Federal Regulations <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-8">specifically excludes baggage</a> from the 7.5% transportation tax as long as “the charge is separable from the payment for the transportation of a person and is shown in the exact amount.” This means if an airline charges a combined $300 to fly you and a bag round-trip within the U.S., it owes $22.50 in tax. If the airline charges $220 to fly you plus separately charges $40 each way for the bag, then your total cost is the same — but the airline only owes the government $16.50 in taxes. Splitting out baggage charges saves the airline $6. Now $6 might not seem like much, but it can add up. Last year, passengers took <a href="https://www.transtats.bts.gov/Data_Elements.aspx?Data=1">more than 800 million trips on major airlines</a>. Even if only a fraction of them check their bags, that means large savings for the industry. How large? The government has <a href="https://www.bts.dot.gov/topics/airlines-and-airports/baggage-fees-airline-2023">tracked revenue from bag fees</a> for decades. In 2002, airlines charged passengers a total of $180 million to check bags, which worked out to around 33 cents per passenger. Today, as any flyer can attest, bag fees are a lot higher. Airlines collected over 40 times more money in bag fees last year than they did in 2002. When the full data is in for 2023, <a href="https://www.bts.dot.gov/baggage-fees">total bag fees</a> will likely top $7 billion, which is about $9 for the average domestic passenger. <a href="https://viewfromthewing.com/the-real-reason-airlines-charge-checked-bag-fees-and-its-not-what-you-think">By splitting out the cost of bags</a>, airlines avoided paying about half a billion dollars in taxes just last year. In the two decades since 2002, flyers paid a total of about $70 billion in bag fees. This means separately charging for bags saved airlines about $5 billion in taxes. <iframe id="88MYD" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/88MYD/2/" width="100%" height="400px" frameborder="0"></iframe> It seems clear to me that tax savings are one driver of the unbundling of baggage fees because of a quirk in the law. The U.S. government doesn’t apply the 7.5% tax to <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-3">international flights that go more than 225 miles</a> beyond the nation’s borders. Instead, there are fixed <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation">international departure and arrival taxes</a>. This is why major airlines charge $35 to $40 <a href="https://www.aa.com/i18n/travel-info/baggage/checked-baggage-policy.jsp">for bags if you’re flying domestically</a>, but don’t charge a bag fee when you’re flying to Europe or Asia. <h2>Do travelers get anything for that money?</h2> This system raises an interesting question: Do baggage fees force airlines to be more careful with bags, since customers who pay more expect better service? To find out, I checked with the Bureau of Transportation Statistics, which has been <a href="https://www.bts.gov/content/mishandled-baggage-reports-filed-passengers-largest-us-air-carriersa">tracking lost luggage for decades</a>. For many years, it calculated the number of mishandled-baggage reports per thousand airline passengers. The government’s data showed mishandled bags peaked in 2007 with about seven reports of lost or damaged luggage for every thousand passengers. That means you could expect your luggage to go on a different trip than the one you are taking about once every 140 or so flights. By 2018, that estimate had fallen to once every 350 flights. In 2019, the government <a href="https://www.bts.gov/topics/airlines-and-airports/number-30a-technical-directive-mishandled-baggage-amended-effective-jan">changed how it tracks</a> mishandled bags, calculating figures based on the total number of bags checked, rather than the total number of passengers. The new data show about six bags per thousand checked get lost or damaged, which is less than 1% of checked bags. Unfortunately, the data doesn’t show improvement since 2019. Is there anything that you can do about higher bag fees? Complaining to politicians probably won’t help. In 2010, two senators <a href="https://www.nj.com/business/2010/04/us_senators_present_bill_to_ba.html">tried to ban bag fees</a>, and their bill went nowhere. Given that congressional action failed, there’s a simple way to avoid higher bag fees: <a href="https://www.cnn.com/travel/article/packing-expert-travel-world-handbag/index.html">travel light</a> and <a href="https://www.nytimes.com/2023/07/08/opinion/carry-on-packing-airlines-lost-luggage.html">don’t check any luggage</a>. It may sound tough not to have all your belongings when traveling, but it might be the best option as bag fees take off.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225857/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jay-l-zagorsky-152952">Jay L.

Amazing money-saving hack hidden in Coles and Woolies Christmas shopping bags

Woolworths and Coles have released specially designed paper bags ahead of the Christmas period, with many praising their multi-purpose usage. The 25 cent bags feature a Christmas design, and are meant to be cut open and reused as wrapping paper for Christmas presents. Shoppers have been sharing their delight at the discovery on social media, with many praising the supermarket giants for encouraging recycling. A member of the North Shore Mums Facebook group shared the revelation, writing, "PSA: the Christmas woolies bags are designed to be cut open and used as wrapping paper." Both Coles and Woolworths bags include cutting lines to help those planning to use them as wrapping this festive season. They added an edit to the post explaining the bags could also be cut into squares around the decorations and used as gift tags. Other alternatives to pricey wrapping paper include tea towels, paper that has been decorated by children in the family or making the most out of reusable gift bags which can be collected and saved for the next occasion. With many families anxious of excess spending during the festive period in the face of the ongoing cost of living crisis, the reusable bags are set to be a welcome hack for those trying to be money conscious this Christmas.

Return and Earn is a great way to recycle

When you recycle your eligible bottles and cans through Return and Earn, the material that is used to make the bottles and cans stay in use for as long as possible and are turned into new products, rather than ending up in landfill or polluting waterways. The scheme has already more than halved the number of drink containers littering our parks, waterways, or ending up in landfill compared to before the scheme was launched in December 2017. What happens to containers returned through Return and Earn? Have you ever wondered what happens to the containers once they are returned through the scheme? All containers returned through Return and Earn are recycled. The containers are picked up from the return points and trucked to a sorting facility where the containers are processed depending on the material type. Cans are crushed and baled into a giant cube, glass bottles are crushed into small particles called cullet; and plastic bottles are sorted by type and colour and shredded into smaller flakes before being turned into pellets. <img class="alignnone size-full wp-image-68727" src="https://www.readersdigest.com.au/wp-content/uploads/2023/08/crushed-cans-770.jpg" alt="" width="770" height="500" /> The giant cubes of Aluminium cans are melted, rolled into sheets, and sent to manufacturers to be turned into new cans or other products – some even go to make up aeroplane parts! Glass cullet is melted and mixed with raw materials before being blown into a new glass bottle and sent to drink companies. The plastic pellets are melted down, moulded and blown into new plastic bottles, ready to be bought be retailers. The new bottles and cans made from the recycled materials are filled by the beverage companies, labelled, capped, and ready to be consumed. By using the recycled material from Return and Earn, we save water, energy, and landfill, as well as reducing the carbon emissions that would be used if new raw materials were used instead. This conservation contributes to a more sustainable and efficient economy. Keeping materials in Australia The purity and quality of the material from Return and Earn plays a crucial role in establishing local recycling facilities so most of the key materials stay in Australia. A key milestone was the opening of the Circular Plastics Australia plant in Albury, NSW, in March 2022. This state-of-the-art PET plastic recycling facility is a joint venture between waste industry and beverage industry partners and is the largest of its kind in Australia. The facility reprocesses 100% of the PET (one of the materials that make up plastic containers) collected through the Return and Earn network of over 600 return points and uses the materials to remake new bottles and other food-grade plastic packaging. All glass collected through the Return and Earn network is also being reprocessed in Australia and contributes to the growing demand of locally sourced glass to use in making new bottles and other products. Having facilities in Australia means that the cycle of making a new container from the recycled material is fast. Plastic bottles can be back on the shelf in as little as six weeks and glass bottles in four weeks. Now that’s recycling at its best. <img class="alignnone size-full wp-image-68725" src="https://www.readersdigest.com.au/wp-content/uploads/2023/08/what-happens-when-you-return-and-earn-journey-image_770.jpg" alt="" width="770" height="846" /> Do you recycle? It’s easier than ever to recycle your empty containers through Return and Earn. We have over 600 return points across Australia, and we continue to work with businesses and local councils to identify more sites. Every container counts – recycling is an important way to reduce the load on our natural resources and keep valuable waste on the path to being remade into new products and used again. These small acts can make a big impact. If you’re not interested in returning the containers, consider leaving them out for others in your neighbourhood that are collecting them, or donate them to a charity or community group who is fundraising through the scheme. If you are unable to give them away, place your empty drink containers in your yellow lid recycle bin. For more information about Return and Earn, and to find your nearest return point visit <a href="https://returnandearn.org.au/">returnandearn.org.au</a> Case Study: Sharing the dignity through recycling Semi-retiree Wendy Pluckrose from the far north NSW coast has supported Share the Dignity for years, so when she discovered Return and Earn it seemed an obvious way to raise some extra funds as well as protect the environment. Share the Dignity is a women's charity in Australia, that works to make a real difference in the lives of those experiencing homelessness, fleeing domestic violence, or doing it tough. Wendy has installed bins at home and at local shops and restaurants to collect eligible drink containers. Most days she collects between 100 – 500 containers, and in the last year has raised nearly $3,500 from around 35,000 containers recycled through Return and Earn. “Return and Earn is just free money!” Wendy said. “It’s a little bit of effort, but it makes a big difference.” <img class="alignnone size-full wp-image-68728" src="https://www.readersdigest.com.au/wp-content/uploads/2023/08/share-the-dignity-photo-article-770.jpg" alt="" width="770" height="733" /> With the containers collected so far, not only is the refund going towards buying women’s sanitary products to women experiencing hardships, but it has also contributed to protecting the environment. By recycling 35,000 containers to be remade into new containers rather than using virgin materials, the environmental savings calculated by the <a href="https://returnandearn.org.au/impact-calculator/">Impact Calculator</a> include 206,000 litres of water; 46 gigajoules of energy that equates to six months of energy consumption for a household; and 2,100 kilograms of material entering landfill. The carbon emissions avoided equates to keeping two cars off the road for 18 months. To learn more about Return and Earn, <a href="https://returnandearn.org.au/">head to their website</a>.

Done with Barbie? How to reuse or recycle old dolls

Bright pink clothing has been a hot item at a number of Brotherhood of St Laurence (BSL) op shops as movie-goers doll up to see Greta Gerwig’s Barbie. <div class="copy"> Kelly McMurray, an area store manager for BSL, says “a lot of 18 – 35 year old women have been coming in to get outfits for premier parties. “It’s been really fun helping people to find their outfits!” The movie has set off a global Barbiecore mania, pinkifying everything and <a href="https://au.news.yahoo.com/barbie-movies-potential-500-million-haul-could-have-huge-implications-for-mattel-123756476.html" target="_blank" rel="noreferrer noopener">driving demand</a> for more plastic dolls and toy company merchandise. Even before the movie, the global population of Barbies was growing by <a href="https://cosmosmagazine.com/people/barbie-science/" target="_blank" rel="noreferrer noopener">around 100 new dolls every minute</a>. Which begs the question: what to do with all those dolls once the gloss of the movie ultimately wears off? For toys still in good condition, reusing them by donating to friends or op shops is an obvious first choice. “Our stores do receive a lot of toys every year,” McMurray says. “The peak of our toy donations would be in the New Year and the second week of every school holidays – when people have either been gifted new toys (after Christmas) and when they have had time to do a clean out – hence the second week of school holidays.” For those seeking a more sustainable supply of Barbie dolls, accessories or merchandise, McMurray suggests visiting one of the bigger BSL stores, as those tend to receive the bulk of toy donations. In Melbourne, the Deer Park op shop has two large sections dedicated to kids toys and clothes, while the Belmont store has been receiving – and selling – a lot of Barbie DVDs. When donating Barbies, or any kind of doll or toy, McMurray says people need to really consider if the toy is in a suitable condition, and isn’t missing any body parts. “A little wear and tear is ok. But if people have any doubts about it – best not to include it in their donations.” For those ‘weird Barbies’ past the point of no return, recycling is the next best option. Research by retailer Flora & Fauna suggests Australians send <a href="https://giftguideonline.com.au/flora-fauna-launches-upcycled-toys-christmas-initiative/" target="_blank" rel="noreferrer noopener">26.8 million toys</a> to landfill every year. Plastic toys are considered harder to recycle than many regular household items, and can not be put in kerbside recycling bins. <iframe title="Think Pink: The Science of Barbie" src="https://omny.fm/shows/huh-science-explained/think-pink-the-science-of-barbie/embed?in_playlist=podcast&style=Cover" width="100%" height="180" frameborder="0"></iframe> Global recycling company TerraCycle offers a toy recycling program for worn out and broken toys in partnership with department store Big W. It’s called ‘Toys for Joy’. Marina Antoniozzi, TerraCycle’s head of operations, says the initiative saw over 18 tonnes of old toys collected in the first year of trial operations in 2021. The program has now collected well over 160 tonnes of toys, she says. “The majority of toys are not kerbside recyclable due to the complex nature of their composition. Toys are frequently made up of several materials including different types of plastics and metals, which means they need to be manually sorted and separated,” Antoniozzi says. The recycling company partners with toy brands and retailers because the cost to collect and process the material is usually more than the value of raw material produced through the recycling process. In Barbie’s case, the doll is made up of a <a href="https://cosmosmagazine.com/people/culture/plastic-artefact-what-is-barbie-even-made-of/" target="_blank" rel="noreferrer noopener">complex mix of different types of plastics</a>. According to a <a href="https://www.mdpi.com/2073-4360/14/20/4287" target="_blank" rel="noreferrer noopener">study by Italian researchers</a> early dolls made between 1959 and 1976 comprised a complex mix of different <a href="https://cosmosmagazine.com/science/explainer-what-is-a-polymer/" target="_blank" rel="noreferrer noopener">polymers</a>: polyvinyl chloride faces and legs; hair from polyvinylidene dichloride; and torsos made from low-density polyethylene. More <a href="http://www.designlife-cycle.com/barbie-dolls" target="_blank" rel="noreferrer noopener">modern dolls</a> have arms of ethylene-vinyl acetate (also used in thongs, and frozen food packaging), torsos of acrylonitrile-butadiene-styrene (also found in Lego), legs from polypropylene, and heads made of hard vinyl (like the kind used in vinyl records). Once collected, the toys sent to TerraCycle for recycling are checked in at TerraCycle’s Materials Recovery Facility where they are manually sorted, separated into individual material streams and prepared for processing. Antoniozzi says that in Australia, TerraCycle processes Barbie dolls and accessories along with other hard plastic toys. These are sent to recycling facilities to be shredded and cleaned. Residual metals are removed using magnets in a process called eddy current separation. The plastics are then sorted into different types using technologies like near infrared, a spectroscopy technique used for analysing and differentiating between polymers. Afterwards, the separated, shredded plastics go through a melting and extrusion process producing recycled plastic pellets, used by manufacturers to make a variety of products. So, when Barbie goes to the recycling plant, she will ultimately be sorted, shredded, melted and turned into plastic pellets. Antoniozzi says donating toys is a good first option. “But if your Barbie is genuinely beyond repair, then you can take her, Ken, Sandy, as well as all her horses, buses, apartments and accessories along to your local BIG W store and give her a second life through the Toys for Joy recycling program,” she says. “Who knows… she may come back to you as a flower pot.” Image credits: Shutterstock  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=258208&title=Done+with+Barbie%3F+How+to+reuse+or+recycle+old+dolls" width="1" height="1" data-spai-target="src" data-spai-orig="" data-spai-exclude="nocdn" /><a href="https://cosmosmagazine.com/earth/sustainability/done-with-barbie-how-to-reuse-or-recycle-old-dolls/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/petra-stock/">Petra Stock</a>. </div>

Why do I have to take my laptop out of the bag at airport security?

<a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Anyone who has travelled by air in the past ten years will know how stressful airports can be. You didn’t leave home as early as you should have. In the mad rush to get to your gate, the security screening seems to slow everything down. And to add insult to injury, you’re met with the finicky request: “laptops out of bags, please”. But what does your laptop have to do with security? <h2>The day that changed air travel forever</h2> Airport security changed dramatically after the terrorist attacks in the US on September 11 2001. Before 9/11, you could pass through security with a carry-on bag full of everything you might need for your holiday, <a href="https://www.npr.org/2021/09/10/1035131619/911-travel-timeline-tsa">including a knife</a> with a four-inch blade. Indeed, that’s how the 9/11 attackers brought their <a href="https://www.npr.org/2021/09/10/1035131619/911-travel-timeline-tsa">weapons on board</a>. After 9/11, screening processes around the world changed overnight. In the US, private security contractors being paid a minimum wage were swapped out for a federalised program with highly trained security personnel. Anything that could be <a href="https://www.frontiersin.org/articles/10.3389/fnhum.2013.00654/full">considered a weapon</a> was confiscated. Around the world, travellers were suddenly required to <a href="https://books.google.com.au/books?hl=en&lr=&id=6hBnJ-1hRp0C&oi=fnd&pg=PA86&dq=why+do+I+have+to+take+my+shoes+off+at+airport+security&ots=o6JIFHJzF1&sig=B6azb6xqN2uxM9CP-VZdfyt3Ag0#v=onepage&q=why%20do%20I%20have%20to%20take%20my%20shoes%20off%20at%20airport%20security&f=false">remove their shoes</a>, belts and outerwear, and take out their phones, laptops, liquids and anything else that could be used as part of an improvised explosive device. This lasted for several years. Eventually, <a href="https://www.sciencedirect.com/science/article/pii/S2212478013000944">more advanced</a> screening methods were developed to effectively identify certain threats. Today, some countries don’t require you to remove your shoes when passing through security. So why must you still take your laptop out? <h2>Airport scanners have come a long way</h2> The machine your bags and devices pass through is an X-ray machine. The main reason you have to remove your laptop from your bag is because its <a href="https://www.smh.com.au/traveller/reviews-and-advice/why-do-i-have-to-remove-my-laptop-from-my-bag-at-the-airport-xray-machine-20170320-gv1vqs.html">battery</a> and other mechanical components are too dense for X-rays to penetrate effectively – especially if the scanning system is old. The same goes for power cords and other devices such as tablets and cameras. With these items in your bag, security officials can’t use the screened image to determine whether a risk is present. They’ll have to flag the bag for a physical search, which slows everything down. It’s easier if all devices are removed in the first place. A laptop inside a bag can also shield other items from view that may be dangerous. Scanning it separately reveals its internal components on the screen. In some cases you might be asked to turn it on to prove it’s an actual working computer. With newer multi-view scanning technology, security officials can view the bag from multiple angles to discern whether something is being covered up, or made to look like something else. For instance, people have tried to <a href="https://www.sciencedirect.com/science/article/pii/S2212478013000944">mix gun parts</a> with other components in an effort to pass checked baggage screening. Some airports have upgraded <a href="https://www.smh.com.au/traveller/inspiration/no-more-removing-liquids-and-gels-laptops-at-melbourne-airport-as-new-scanners-installed-20191002-h1ijdf.html">3D scanning</a> that allows travellers to pass their bags through security without having to remove their laptops. If you’re not asked to take out your laptop, it’s probably because one of these more expensive systems is being used. Nonetheless, amping up the technology won’t remove the lag caused by airport screenings. Ultimately, the reason these are a major choke point is because of the speed at which staff scan the imagery (which dictates the <a href="https://www.sciencedirect.com/science/article/pii/S2212478013000944">speed of the conveyor belt</a>). Unless we find a way to automate the entire process and run it with minimal human supervision, you can expect delays. <h2>What about body scanners?</h2> But your bags aren’t the only thing getting scanned at airport security. You are too! The tall frame you walk through is a <a href="https://science.howstuffworks.com/transport/flight/modern/airport-security3.htm">metal detector</a>. Its purpose is to uncover any weapons or other illegal objects that may be concealed under your clothes. Airport metal detectors use non-ionising radiation, which means they don’t emit X-rays. The larger body scanners, on the other hand, are a type of X-ray machine. These can be <a href="https://www.sciencedirect.com/science/article/pii/S2212478013000944">active or passive</a>, or a combination of both. Passive scanners simply detect the natural radiation emitted by your body and any objects that might be concealed. Active scanners emit low-energy radiation to create a scan of your body, which can then be analysed. The kind of machine you walk through will depend on where in the world you are. For instance, one type of active body scanner that emits X-rays in what’s called “backscatter technology” was once <a title="https://electronics.howstuffworks.com/gadgets/high-tech-gadgets/backscatter-x-ray.htm" href="https://electronics.howstuffworks.com/gadgets/high-tech-gadgets/backscatter-x-ray.htm" target="_blank" rel="noopener">used widely</a> in the US, but is no longer used. It’s also banned in <a title="https://www.homeaffairs.gov.au/about-us/what-we-do/travelsecure/passenger-screening" href="https://www.homeaffairs.gov.au/about-us/what-we-do/travelsecure/passenger-screening" target="_blank" rel="noopener">Australia</a> and <a title="https://www.forbes.com/sites/daviddisalvo/2011/11/15/europe-bans-airport-body-scanners-over-health-and-safety-concerns/" href="https://www.forbes.com/sites/daviddisalvo/2011/11/15/europe-bans-airport-body-scanners-over-health-and-safety-concerns/" target="_blank" rel="noopener">the European Union</a>, where only non-ionising technology can be used. Another type of scanner emits lower-energy <a href="https://science.howstuffworks.com/backscatter-machines-vs-millimeter-wave-scanners.htm">millimetre waves</a>, instead of X-rays, to image the passenger. Millimetre wave frequencies are considered to be non-ionising radiation. <h2>AI in our airports</h2> AI seems to be all around us lately, and our airports are no exception. Advancements in AI systems stand to transform the future of airport security. For now, human reviewers are required to identify potential threats in scanned images. However, what if an advanced <a href="https://thinkspace.csu.edu.au/artiificialintelligenceinsecuritycheck/article/">AI was trained</a> to do this using a database of images? It would do so in a fraction of the time. Some airports are already using advanced <a href="https://www.in-security.eu/index.php/editorial/the-future-of-airport-security-faster-smarter-safer">computed tomography</a> (CT) <a href="https://www.theguardian.com/australia-news/2022/jun/21/3d-body-scanners-at-australian-airports-what-are-they-and-how-do-they-work">scanners</a> to produce high-definition 3D imagery. In the future, this technology could be further enhanced by AI to detect threats at a much faster rate. Hypothetically, CT scans could also be used for both humans and their baggage. Could this allow travellers to walk through a body scanner while carrying their bags? Possibly. Until then, you should probably try your best to leave the house on time.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/209041/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, Professor/Head of Aviation, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

3 little-known reasons why plastic recycling could actually make things worse

<a href="https://theconversation.com/profiles/pascal-scherrer-230971">Pascal Scherrer</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> This week in Paris, negotiators from around the world are <a href="https://www.unep.org/events/conference/second-session-intergovernmental-negotiating-committee-develop-international">convening</a> for a United Nations meeting. They will tackle a thorny problem: finding a globally binding solution for plastic pollution. Of the staggering <a href="https://stats.oecd.org/viewhtml.aspx?datasetcode=PLASTIC_USE_6&lang=en">460 million tonnes of plastic used globally in 2019 alone</a>, much is used only once and thrown away. About <a href="https://www.oecd.org/environment/plastic-pollution-is-growing-relentlessly-as-waste-management-and-recycling-fall-short.htm">40% of plastic waste</a> comes from packaging. Almost two-thirds of plastic waste comes from items with lifetimes of less than five years. The plastic waste that escapes into nature persists and breaks up into smaller and smaller pieces, <a href="https://www.science.org/doi/10.1126/sciadv.1700782">eventually becoming microplastics</a>. Plastics now contaminate virtually every environment, from <a href="https://www.theguardian.com/environment/2020/nov/20/microplastic-pollution-found-near-summit-of-mount-everest">mountain peaks to oceans</a>. Plastic has entered vital systems such as our food chain and even the human <a href="https://www.theguardian.com/environment/2022/mar/24/microplastics-found-in-human-blood-for-first-time">blood stream</a>. Governments and industry <a href="https://www.un.org/en/climatechange/nations-agree-end-plastic-pollution">increasingly acknowledge</a> the urgent need to reduce plastic pollution. They are introducing <a href="https://apco.org.au/the-australian-packaging-covenant">rules and incentives</a> to help businesses stop using single-use plastics while also encouraging collection and recycling. As a sustainability researcher, I explore opportunities to <a href="https://www.scu.edu.au/research/zerowaste/">reduce plastic waste </a>in sectors such as tourism, hospitality and meat production. I know how quickly we could make big changes. But I’ve also seen how quick-fix solutions can create complex future problems. So we must proceed with caution. <blockquote class="twitter-tweet"> The best way to tackle plastic pollution is to prevent it in the first place. Governments, businesses, civil society, and academia can all be part of the solution to <a href="https://twitter.com/hashtag/BeatPlasticPollution?src=hash&ref_src=twsrc%5Etfw">#BeatPlasticPollution</a>.

For plastics, that means reuse or recycling back into the same type of plastic, not lower grade plastic. The plastic can be used to make similar products that then can be recycled again and again. This means plastics should only be used where they can be captured at their end of life and recycled into a product of the same or higher value, with as little loss as possible. Probably the only example of this to date is the recycling of PET (polyethylene terephthalate) soft-drink bottles in Norway and Switzerland. They boast recovery rates of <a href="https://phys.org/news/2020-02-norway-bottles-plastic-fantastic.html">97%</a> and <a href="https://houseofswitzerland.org/swissstories/environment/switzerland-leads-way-pet-recycling">95%</a> respectively. The <a href="https://wastewise.be/2014/11/ad-lansink/">waste management pyramid</a> below shows how to prioritise actions to lessen the waste problem. It is particularly relevant to single-use plastics. Our top priority, demanding the biggest investment, is prevention and reduction through redesign of products. Where elimination is not yet achievable, reuse solutions or recycling to the same or higher-level products can be sought to make plastics circular. <figure class="align-center "><img src="https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=406&fit=crop&dpr=1 600w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=406&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=406&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=510&fit=crop&dpr=1 754w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=510&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=510&fit=crop&dpr=3 2262w" alt="Inverted pyramid diagram showing waste management priorities" /><figcaption>In the inverted pyramid of waste management priorities, downcycling is almost the last resort. Pascal Scherrer</figcaption></figure> Unfortunately, a lack of high-quality reprocessing facilities means plastic waste keeps growing. In Australia, plastic is largely “downcycled”, which means it is recycled into lower quality plastics. This can seem like an attractive way to deal with waste-plastic stockpiles, particularly after the recent collapse of soft-plastics recycler <a href="https://theconversation.com/redcycles-collapse-is-more-proof-that-plastic-recycling-is-a-broken-system-194528">RedCycle</a>. But downcycling risks doing more harm than good. Here are three reasons why: <h2>1. Replacing wood with recycled plastics risks contaminating our wildest natural spaces</h2> An increasing number of benches, tables, bollards and boardwalks are being made from recycled plastic. This shift away from timber is touted as a sustainable step - but caution is warranted when introducing these products to pristine areas such as national parks. Wood is naturally present in those areas. It has a proven record of longevity and, when degrading, does not introduce foreign matter into the natural system. Swapping wood for plastic <a href="https://www.sciencedirect.com/science/article/abs/pii/S0269749122019510?via%3Dihub">may introduce microplastics</a> into the few remaining places relatively free of them. Replacing wood with downcycled plastics also risks plastic pollution through weathering or fire. <h2>2. Taking circular plastics from their closed loop to meet recycled-content targets creates more waste</h2> Clear PET bottles used for beverages are the most circular plastic stream in Australia, approaching a 70% recovery rate. When these bottles are recycled back into clear PET bottles, they are circular plastics. However, the used PET bottles are increasingly being turned into meat trays, berry punnets and <a href="https://www.praise.com.au/faqs-100-recycled-bottles">mayonnaise jars</a> to help producers meet the <a href="https://apco.org.au/national-packaging-targets">2025 National Packaging Target</a> of 50% recycled content (on average) in packaging. The problem is the current industry <a href="https://anzpacplasticspact.org.au/wp-content/uploads/2021/06/Recovered-Polymer-Specifications_FINAL_June2021d.pdf">specifications for plastics recovery</a> allow only downcycling of these trays, punnets and jars. This means that circular PET is removed from a closed loop into a lower-grade recovery stream. This leads to non-circular downcycling and more plastic sent to landfill. <h2>3. Using “compostable” plastics in non-compostable conditions creates still more plastic pollution</h2> Increasingly, plastics are labelled as compostable and biodegradable. However, well-intended use of compostable plastics can cause long-term plastic pollution. At the right temperature with the right amount of moisture, compostable plastics breakdown into soil. But if the conditions are not “just right”, they won’t break down at all. For example, when a landscape architect or engineer uses a “compostable” synthetic fabric instead of a natural alternative (such as coir or jute mats) they can inadvertently introduce persistent plastics into the environment. This is because the temperature is not hot enough for the synthetic mat to break down. We must also <a href="https://documents.packagingcovenant.org.au/public-documents/Considerations%20for%20Compostable%20Packaging">differentiate</a> between “home compostable” and “commercially compostable”. Commercial facilities are more effective at composting because they operate under more closely controlled conditions. <blockquote class="twitter-tweet"> Plastic pollution could reduce by 80% by 2040 if governments and companies make policy and market shifts using existing technologies. OUT NOW – UNEP’s new report provides a pathway for nations to <a href="https://twitter.com/hashtag/BeatPlasticPollution?src=hash&ref_src=twsrc%5Etfw">#BeatPlasticPollution</a>: <a href="https://t.co/dcfBkZaOfN">https://t.co/dcfBkZaOfN</a> <a href="https://t.co/iSQ9QSpYC1">pic.twitter.com/iSQ9QSpYC1</a> — UN Environment Programme (@UNEP) <a href="https://twitter.com/UNEP/status/1658419925638152192?ref_src=twsrc%5Etfw">May 16, 2023</a></blockquote> <h2>Learning from our mistakes</h2> Clearly, we need to reduce our reliance on plastics and shift away from linear systems – including recycling into lower-grade products. Such downcycling may have a temporary role in dealing with existing plastic in the system while circular recycling capacity is being built. But we must not develop downcycling “solutions” that need a long-term stream of plastic waste to remain viable. What’s more, downcycling requires constantly finding new markets for their lower-grade products. Circular systems are more robust. So, to the negotiators in Paris, yes the shift to a circular plastics economy is urgent. But beware of good intentions that could ultimately make things worse.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/206060/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/pascal-scherrer-230971">Pascal Scherrer</a>, Senior Lecturer, Faculty of Business, Law and Art, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Microwaving solar panels makes them easier to recycle

<div> <a href="https://cosmosmagazine.com/news/solar-cells-essential-for-brighter-future/" target="_blank" rel="noreferrer noopener">Solar cell</a> manufacturing and recycling should be easier with a surprising new discovery by Macquarie University scientists – that uses a commercial microwave. While they’re being made, the silicon in solar panels goes through a process called “annealing”, which involves heating the materials to temperatures well above 500°C. Annealing is usually done with ovens. But a study <a href="https://doi.org/10.1063/5.0127896" target="_blank" rel="noreferrer noopener">published</a> in Applied Physics Letters shows that microwaves are not only faster and more energy efficient for the job, but make the panels much easier to disassemble, and thus recycle, at the end of life. This is because microwave radiation heats individual substances – like the water in food, or silicon. “It just heats the very thin layer of silicon rather than heating the bulk of the materials around, and it’s really fast,” says lead author Dr Binesh Puthen Veettil, a researcher at Macquarie University’s School of Engineering. This also makes the process easier, because the microwave doesn’t have to be as carefully cleaned. “In most of the high temperature processes, lots of contaminants come out of the walls of the oven. But in this case, the heat is flowing from the silicon outwards, while everything else is at room temperature, it’s kind of a pseudo room temperature process where the contaminants don’t get diffused from outside,” says Veettil. “But the thing we are most excited about is the benefit to recycling.” Currently, solar cell recycling is a very <a href="https://cosmosmagazine.com/earth/sustainability/solar-panel-recycling/" target="_blank" rel="noreferrer noopener">energy intense process</a> which involves crushing up the panels and heating them to temperatures of at least 1000°C, so that all of the expensive elements can be extracted. This method destroys some of the reusable solar cell components: particularly, the toughened glass on the top of the panel. “This glass contains most of the weight of the solar panel,” explains Veettil. That glass is stuck to a layer of plastic, usually ethylene vinyl acetate, which keeps the silicon plate underneath dry. This plastic is too hard to remove, so the whole thing is smashed up, with the glass sold as scrap. But microwaving the silicon specifically softens the plastic, making it easy to peel. “You can just peel off the silicon cell, without destroying the glass, and you can reuse that expensive glass,” says Veettil. “If you can reuse the glass, the recycling will pay for itself.” Plus, it doesn’t need the same high temperatures, or extra chemicals needed to wash and dissolve the plastic. For now, the process is lab-based – and only for solar panels that fit in a commercial microwave. “Initially, when we started the research, we used a laboratory microwave that we purchased from a US company,” says Veettil. “And we after that, we purchased some kitchen microwaves locally, and modified it to suit our purposes.” This modification involved heat-proofing the microwave so that it could handle the annealing temperatures. “It goes from room temperature to 500° Celsius in just two seconds,” says Veettil. (Depending on the size of the sample: bigger things take longer.) But the researchers have a patent pending for the recycling process, and are now investigating how to improve and commercialise it. “We are hoping that with some industry collaboration and funding, we can scale it up,” says Veettil. “Recycling needs to be meet two conditions: it should be environmentally friendly, and second, it should pay for itself. “I’m pretty sure, with the numbers I have in mind, it will it will be profitable and then the market will take care of itself and it organically grow recycling centres. That’s my hope.” </div> <div id="contributors"> This article was originally published on <a href="https://cosmosmagazine.com/technology/microwaving-solar-panels-recycling/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Ellen Phiddian.

What's inside the $126k Oscars gift bags?

For many actors, being awarded an Oscar is the greatest gift of their career. However, if an actor misses out in their category, it doesn't mean they'll walk away with nothing. The Oscars' gift bags have long been jam-packed with a selection of luxury goods, bringing the total value of the goodies well into the six-figure mark. This year is no exception, with the Los Angeles-based marketing company Distinctive Assets once again sending out its infamous "Everybody Wins" swag bags to the top nominees. The bags are worth an impressive $126,000 this year, with 26 nominees in acting and directing categories going home with the goodies. The celebrities will be offered thousands of dollars worth of luxury goods, and even more in vouchers for things like vacations and cosmetic procedures. Among the contents is a luxury getaway to Canada, which is said to be valued at $40,000, vouchers for cosmetic procedures like liposuction and micro-needling, luxury skincare and gourmet foods, and and "the first-ever chocolate box with a personalised video embedded inside." Also in the goodie bag is one unusual gift that has caused outrage with Indigenous Australian communities: a plot of land in regional areas of Australia. Pieces of Australia is one of a number of brands to pay $4,000 to secure a spot in the Oscars gift bag, offering a small parcel of land in outback Australia as part of its “Conservation Gift Packs”. The land parcels all come with a “certificate of land licence”, but the terms and conditions go on to state that “you have purchased a symbolic souvenir … of the land” and people who own a “pack” may not “take possession of the parcel; use the parcel; enter upon the parcel and/or the land without the licensor’s express written consent”. The digital “member’s handbook” which comes with the pack referenced the Indigenous Carbon Industry Network (ICIN) without the company's permission, causing outrage with the traditional owners of the land. In a statement, ICIN said it “has not granted permission for any of our information, publications or photos to be reproduced to support the Oscars ‘Goodie Bag’ or ‘Pieces of Australia’.” “The Indigenous Carbon Industry Network is a 100% Indigenous-owned charitable company owned by 23 Indigenous organisations across Australia,” it said. “ICIN is seeking legal advice regarding this matter and will be able to provide further statement once we have sought appropriate advice.” The Pieces of Australia founder, Niels Chaneliere, said the intention of his organisation was to provide “land licence agreements (where there is no land title transfer at any point) as novel/symbolic gifts for people around the world to engage and participate positively in conservation efforts”.

The most feel-good way to recycle

Long-time Return and Earner "Scooter Dave" has been a keen participant in the NSW container deposit scheme since the program started, and the Illawarra local has returned 500,000 containers in that time. Dave gets about on a scooter and any day when weather and health permits, he completes his route to collect rubbish from Windang Bridge in Shellharbour. Along the way he picks up eligible drink containers from residents and businesses who keep them in their yards ready for his scooter collection service. He has donated all of the $50,000 in refunds to many charities, including the Smith Family, the Sydney Children’s Hospital, and children’s ward in Wollongong, bushfire appeals and the Illawarra Convoy. “It gives me something to do, and I know that I am doing something to help people," says Scooter Dave. "People always say that there should be more people like me. There are, but they aren’t cleaning up rubbish like I am.” In a world that’s becoming more eco-conscious, we’re seeing more and more initiatives implemented to reduce the impact we’re having on the planet – from the single-use plastic bans to adopting reusable packaging and recycling. Recycling remains one of the best ways to help protect the environment. The benefits of recycling include reducing the amount of rubbish that ends up in landfill or as litter in our local environment, and reducing the need to extract raw materials from the earth to create new products such as mining raw aluminium to create cans. And with <a style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;" href="https://returnandearn.org.au/?utm_source=over-60&utm_medium=article&utm_content=native-article&utm_campaign=grey-partnership" target="_blank" rel="noopener">Return and Earn</a> there are even more direct benefits for you. Return and Earn is one of many drink container return schemes that have been adopted around the world, where customers who return their used eligible drink containers for recycling can collect a refund. “With Return and Earn, you earn a 10c refund for every empty can, glass or plastic bottle, carton, juice box or popper that you return through one of its 600 return points across NSW. “Since the scheme launched five years ago, over 8.6 billion containers have been returned for recycling by the NSW public resulting in over $860 million in container refunds back in people’s pockets,” says Danielle Smalley, CEO of Exchange for Change, scheme coordinator for Return and Earn. The scheme is entirely funded by the beverage industry, aiming to place responsibility for container recycling firmly back with the industry. The scheme targets commonly littered items and includes most 150ml to three litre plastic, glass, aluminium, steel, and liquid paperboard containers. Eligible containers featuring the 10 cent refund mark can be redeemed for the refund. “Return and Earn is an extraordinary example of how individual action can have a collective impact,” says Smalley. The environmental benefits of the scheme have exceeded expectations – reducing the volume of drink container litter by 52 per cent compared to pre-scheme levels and sending over 755,000 tonnes of material to be recycled. Plus the Return and Earn app makes recycling your containers even easier because you can check the map to see where the nearest return points are to your location and make sure they’re open. Another fantastic feature on the app is the container checker which helps you avoid taking containers that are not eligible. Simply scan the barcode on your container and the app tells you if it can be returned for recycling at a return points. If not, they can go straight into your household recycling bin. Choose your recycling experience To return your containers, you can choose from four types of return points, depending on what suits you and what is nearby. There are Return and Earn machines - a self-service option where you return your containers one-at-a time. You’ll receive a receipt which is redeemable for cash at the partner redemption location or payment straight to your bank account by downloading the Return and Earn app. There are also Return and Earn Centres which are larger format indoor locations featuring multiple machines inside. <img src="https://oversixtydev.blob.core.windows.net/media/2023/01/Tomra1.png" alt="Return and Earn" width="741" height="423" /> For larger numbers, heading to your nearest automated depot is your best option. Here staff will take your bags of eligible containers and process them in their automated counting system called a singulator. Once counted, they’ll provide you with your cash refund. Even local businesses are taking part, with some corner stores, newsagents, fruit shops and some Surf Life Saving Clubs able to take your containers and give you your refund.

Top tips for returning and earning When you’re ready to return your first collection of containers, here are some tips to make your experience even easier: <ul> <li>Download the Return and Earn app: use the app store available on your mobile phone. </li> <li>Sort your containers before you go: if you’re using a Return and Earn machine, sort your glass containers from your plastic bottles and cans as these are return using separate chutes on the machine. If you’re using an automated depot or an over-the-counter return point, there’s no need to sort. </li> <li>Check if your containers are eligible: Use the Return and Earn app to check if your containers are eligible for a refund. And make sure they’re uncrushed, with the barcode visible and keep the lid on.</li> <li>Plan your trip: make sure to check opening times of your nearest return point via the Return and Earn app or website.

Here’s how you can bag a night at Bag End

While many visitors to New Zealand’s Hobbit movie set have gone there and back again, no-one has had the chance to stay overnight - until now that is. In celebration of the 10th anniversary of The Hobbit: An Unexpected Journey, Airbnb will be offering a few lucky fans the opportunity to spend the night at the original movie set. Winners will score one of three overnight stays at the set in Waikato, with access to the Hobbit Holes, Millhouse and The Green Dragon Inn, a private tour of the movie set, and an evening banquet in the Green Dragon - think beef and ale stew, fresh bread, chickens and ale. Two decades after the working farm caught the attention of Lord of the Rings director Peter Jackson, the farm’s owner Russell Alexander said he was excited to offer guests the experience of living like a Hobbit. “We’ve welcomed millions of passionate fans to the Hobbiton Movie Set, but never before has anyone had the opportunity to spend a night in Middle-earth,”he said. “I am delighted to share the beauty of my family’s farm and pleased to be hosting this iconic location on Airbnb for fans from around the world.” The three two-night stays will come with a four-guest limit and cost $NZ 10 ($AU 9.46) a night to mark the 10th anniversary. Each of the stays will take place on March 2-4, 9-11 and 16-18. Unsurprisingly, there are some rules for the lucky guests who stay on-set, with plenty of references to the Hobbit and Lord of the Rings sagas, including “no unexpected parties”, “magical rings permitted, but keep them secret, keep them safe”, “straying far at night is discouraged, thanks to multiple troll sightings of late”, and “pony parking” available only at the Green Dragon Inn. To go in the running, applicants can request to book one of the stays from Wednesday December 14. Applicants must have a history of positive reviews on Airbnb, have an Airbnb profile and be over the age of 18.

Dog found hidden in carry-on bag at airport security

A US Transportation and Security Agency (TSA) officer has discovered a small dog stashed in a traveller's carry-on luggage. The animal was found in a backpack when going through the X-ray machine at the Dane County <a title="Airport " href="https://www.9news.com.au/airport" target="_blank" rel="noopener">Airport</a> in Wisconsin. TSA told a local news outlet that the passenger was unaware of the screening protocol and did not tell security officers about her dog. After an officer explained the proper process and confirmed she disclosed she was travelling with a pet to the airline, she proceeded to her gate to board her flight.

Major change being trialled in Coles to reduce waste

Coles has announced that they will be removing plastic bags from their fruits and vegetables section in a bid to reduce the use of single plastic. The supermarket will trial the removal of plastic bags at their ACT stores from 31 August until 13 September. Customers will be required to bring their own bags from home or can otherwise purchase reusable mesh fresh produce bags. In a bid to help customers, shoppers who spend $5 in store on fruit and veggies will receive a free 3-pack of reusable mesh fresh produce bags that is made from 90 per cent recycled materials. Once the trial is over, all 12 Coles stores will have single use bags for fresh produce removed from September 14. Coles Chief Operations and Sustainability Officer Matt Swindells explained that the initiative is one of the many ways the supermarket is looking to reduce waste. “Under our Together to Zero waste ambition, we are always looking for ways to reduce reliance on unnecessary and problematic single-use plastics packaging and provide sustainable solutions to our customers,” he said. “This will be the first time a major Australian supermarket will trial a completely reusable method of helping customers purchase their fresh fruit and veggies. “We will be looking closely at how our ACT customers respond. These insights will inform our consideration for potentially rolling this out to our customers nationally.” It comes as Coles rolled out fresh produce bags nationally that are made from 50 per cent recycled plastic. The bags can be returned to REDcycle bins at Coles supermarkets to be recycled. Image: Supplied

Brands are leaning on ‘recycled’ clothes to meet sustainability goals

Today we make more clothing than ever before. And the driver for this is primarily economic, rather than human need. Over the past decade, the term “circular economy” has entered the fashion industry lexicon, wherein materials are made to be reused and recycled by design. Yet we haven’t seen the same level of recycling in fashion as we have in other spaces – such as with plastic recycling, for instance. And this is mainly because clothing-to-clothing recycling is much more difficult. The use of recycled polyester and cotton by brands such as H&M and Cotton On are key aspects of these companies’ sustainability initiatives – but the source of these recycled fibres usually isn’t clothing. Recycled polyester tends to <a href="https://artsandculture.google.com/story/zwUxmcq5wIZqLA" target="_blank" rel="noopener">come from plastic bottles</a>, and recycled cotton is usually made from manufacturing waste. The fact is most clothing is simply not designed to be recycled. Even when it is, the fashion industry lacks the kind of infrastructure needed to really embrace a circular economy model. Why is recycling clothes difficult? Recycling clothing isn’t like recycling paper, glass or metal. Clothes are endlessly variable and unpredictable. So they’re not ideal for recycling technologies, which require a steady and consistent source material. Even a seemingly simple garment may contain multiple materials, with fibre blends such as cotton/polyester and cotton/elastane being common. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/469705/original/file-20220620-24-w9gmlu.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/469705/original/file-20220620-24-w9gmlu.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/469705/original/file-20220620-24-w9gmlu.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=292&fit=crop&dpr=1 600w, https://images.theconversation.com/files/469705/original/file-20220620-24-w9gmlu.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=292&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/469705/original/file-20220620-24-w9gmlu.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=292&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/469705/original/file-20220620-24-w9gmlu.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=367&fit=crop&dpr=1 754w, https://images.theconversation.com/files/469705/original/file-20220620-24-w9gmlu.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=367&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/469705/original/file-20220620-24-w9gmlu.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=367&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Despite seeming simple, clothes are complex products containing many components and materials. This means recycling them is very difficult. Shutterstock</figcaption></figure> Different fibres have different capacities for recycling. Natural fibres such as wool or cotton can be recycled mechanically. In this process the fabric is shredded and re-spun into yarn, from which new fabric can be woven or knitted. However, the fibres become shorter through the shredding process, resulting in a lower quality yarn and cloth. Recycled cotton is often mixed with virgin cotton to ensure a better quality yarn. Most fabrics are also dyed with chemicals, which can have implications for recycling. If the original fabric is a mixture of many colours, the new yarn or fabric will likely need bleaching to be dyed a new colour. A complex garment such as a lined jacket easily contains more than five different materials, as well as trims including buttons and zippers. If the goal of recycling is to arrive at a material as close to the original as possible, all the garment’s components and fibres would first need to be separated. This requires labour and can be expensive. It’s often easier to shred the garment and turn it into a low-quality product, such as <a href="https://www.cjr.org/language_corner/shoddy.php" target="_blank" rel="noopener">shoddy</a> which is used for insulation. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/469714/original/file-20220620-20-6cxi7m.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/469714/original/file-20220620-20-6cxi7m.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/469714/original/file-20220620-20-6cxi7m.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/469714/original/file-20220620-20-6cxi7m.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/469714/original/file-20220620-20-6cxi7m.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/469714/original/file-20220620-20-6cxi7m.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/469714/original/file-20220620-20-6cxi7m.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/469714/original/file-20220620-20-6cxi7m.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Massive amounts of clothing scraps are stacked on top of each other, loosely sorted by colour." /></a><figcaption>Even if a garment is designed to be recyclable, if the infrastructure needed is missing, it will likely still end up in landfill. </figcaption></figure> Industry progress and challenges Companies such as <a href="https://www.blocktexx.com/" target="_blank" rel="noopener">BlockTexx</a> and <a href="https://www.evrnu.com/" target="_blank" rel="noopener">Evrnu</a> have developed processes to recycle fibres from blended fabrics, though such recycled fibres aren’t yet widely available. Through a proprietary technology, BlockTexx separates cellulose (present in both cotton and linen) and polyester from textile and clothing waste for new uses, including in new clothing. And Evrnu has developed <a href="https://www.evrnu.com/nucycl" target="_blank" rel="noopener">a type of lyocell</a> made entirely from textile and clothing waste. Spain-based company <a href="https://recoverfiber.com/products/rcotton" target="_blank" rel="noopener">Recover</a> meticulously sorts through different kinds of cotton textile waste to produce high quality, mechanically recycled, cotton fibre. There’s also biological recycling. Fibre waste from the <a href="https://www.abc.net.au/news/2020-07-04/cotton-compost-turns-trash-to-treasured-fertiliser/12410248" target="_blank" rel="noopener">Rivcott cotton “gin”</a> (or cotton engine) is composted to become fertiliser for a new cotton crop. The same is possible with natural fibres from worn-out clothing, after potentially toxic dyes and chemicals have been eliminated. Synthetic fibres such as polyester and polyamide (nylon) can also be recycled mechanically and chemically. Chemical recycling through re-polymerisation (where the plastic fibre is melted) is an attractive option, since the quality of the original fibre can be maintained. In theory it’s possible to use polyester clothing as the source for this. But in practice the source is usually bottles. This is because clothing is usually “contaminated” with other materials such as buttons and zippers, and separating these is too labour intensive. The plastic problem Almost all recycled polyester in clothing today comes from recycled plastic bottles, rather than previous polyester clothing. This is significant when you consider polyester accounts for more than 60% of all fibre use. Given the rapid increase in the production of <a href="http://changingmarkets.org/wp-content/uploads/2021/01/FOSSIL-FASHION_Web-compressed.pdf" target="_blank" rel="noopener">synthetic fibres</a>, and the as-yet-unknown impact of microplastics (which were <a href="https://www.sciencedirect.com/science/article/pii/S0160412020322297" target="_blank" rel="noopener">documented in human placentas</a> last year) – the question remains whether clothing should be made from biologically incompatible materials at all. Polyester clothes, regardless of fibre sources, contribute to microplastic pollution by shedding fibres when worn and laundered. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/469721/original/file-20220620-26-z0f5f8.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/469721/original/file-20220620-26-z0f5f8.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/469721/original/file-20220620-26-z0f5f8.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/469721/original/file-20220620-26-z0f5f8.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/469721/original/file-20220620-26-z0f5f8.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/469721/original/file-20220620-26-z0f5f8.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/469721/original/file-20220620-26-z0f5f8.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/469721/original/file-20220620-26-z0f5f8.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="Plastic bottles are ready to be used for recycling" /></a><figcaption>Although plastic bottles can be recycled into clothing, that clothing is very difficult to further recycle.

Reduce and reuse before you recycle There’s plenty of evidence that reducing the consumption of clothing by wearing items longer and buying second-hand is preferable to purchasing recycled fibre clothes. But even second-hand fashion isn’t without problems when you consider the scale and pace of clothing production today.

Prince Charles denies wrongdoing for reportedly accepting bags of cash

Prince Charles reportedly accepted a suitcase containing €1 million ($AUD 1.52 million) in cash from a Qatari sheikh in 2015, according to recent reports - and it is one of three payments that will be reviewed by the UK’s Charity Commission. According to The Sunday Times, the senior royal received a total of €3 million ($AUD 4.57 million) from Sheikh Hamad bin Jassim bin Jaber Al Thani, the former prime minister of Qatar, between 2011 and 2015. Clarence House has denied that there was any wrongdoing in Charles’ acceptance of the money as charity donations and said the money was “passed immediately to one of the prince’s charities who carried out the appropriate covenants and assured us that all the correct processes were followed”. On one occasion, Charles reportedly received €1 million in carrier bags from high-end grocer Fortnum & Mason. At another, in 2015, Charles accepted another €1 million in a holdall during a one-on-one meeting at Clarence House. Two advisors from the royal household reportedly counted the cash by hand, which was said to be made up of now-discontinued €500 notes, which earned the nickname “bin Laden” because of links to funding terrorism, per <a href="https://honey.nine.com.au/royals/prince-charles-denies-any-wrongdoing-over-bags-of-cash-claim/0face1c8-1ebb-4139-a91c-9c9aa0dee13c" target="_blank" rel="noopener">9Honey</a>. The money was understood to have been collected by private bank Coutts, with each payment being deposited into the accounts of the Prince of Wales’ Charitable Fund (PWCF). As the prince’s meetings with Hamad were private, they don’t appear in the Court Circular - the official record of court engagements - but they do raise questions about how much Charles knew about the cash and where it came from. Sir Ian Cheshire, the chairman of PWCF, said on Friday that “there was no failure of governance” in relation to the organisation receiving the funds. “At a few hours’ notice from The Sunday Times, we have checked into this event in the past, and confirm that the previous trustees of PWCF discussed the governance and donor relationship, (confirming that the donor was a legitimate and verified counterparty) and our auditors signed off on the donation after a specific enquiry during the audit. There was no failure of governance.” After confirming that he was referring to the 2015 payment, Sir Cheshire added: “I believe the same assurance applied to earlier donations and look forward to confirming that in due course.” Though there is no suggestion that the payments were illegal, a Charity Commission spokesperson said on Sunday that they will be reviewed by the Commission. “We are aware of reports about donations received by the Prince of Wales’ Charitable Foundation,” they said in a statement. “We will review the information to determine whether there is any role for the Commission in this matter.” It comes as London police continue to investigate a separate allegation that the prince’s top aide, Michael Fawcett, offered to help a Saudi billionaire secure a knighthood and British citizenship if he donated to The Prince’s Foundation, another of Charles’ charities. Fawcett resigned from his role as chief executive of the foundation in light of the allegations. “We are disappointed not to have been given more time to look into this matter, which dates from a decade ago,” Clarence House said in relation to reports from The Sunday Times. “In the few hours we have had on a Saturday, we have confirmed that Charitable donations were received from sheikh Hamad bin Jassim, and these were passed immediately to one of the prince’s charities who carried out the appropriate governance and have assured us that all the correct processes were followed.” Image: @clarencehouse (Instagram)

At-home dialysis for the cost of a bag of chips

<div> <div class="copy"> A new low-carbon-footprint dialysis treatment might soon be available for the cost of a bag of chips. Sydney-based start-up Ellen Medical Devices has received $427,000 in government funding to develop the award-winning <a rel="noreferrer noopener" href="https://www.ellenmedical.com/the-device/" target="_blank">Ellen Medical Dialysis System</a>. <div class="wp-block-embed__wrapper"> <div class="entry-content-asset"> <div class="embed-wrapper"> <div class="inner"><iframe title="1.4 million people die every year in India because they cannot afford dialysis" width="500" height="281" src="https://www.youtube.com/embed/nF7vMdckIxc?feature=oembed&enablejsapi=1&origin=https://cosmosmagazine.com" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen=""></iframe></div> </div> </div> </div> Dialysis replaces normal kidney function by purifying and cleaning the blood when kidneys alone can’t do it. It has been a common and effective treatment for kidney failure for 70 years but the rate of kidney failure is <a rel="noreferrer noopener" href="https://cosmosmagazine.com/health/geographical-health-data-australia/" target="_blank">increasing</a> globally. “The number of people needing treatment for kidney failure is predicted to double to over five million by 2030,” says Ellen Medical Managing Director John Knight, a kidney specialist and UNSW Sydney professor of medicine. “This is not only a preventable human tragedy but a significant market opportunity.” On top of this, dialysis costs around $85,000 per year. This might be covered by insurance in high-income countries, but the cost is prohibitive for many people in low income countries. In fact, 75% of people who require dialysis around the world can’t afford it, and face death as a result. “Families try the best they can to pay for the treatment and often they’ll suffer quite severe financial hardship,” says Knight. “They can often lose their house in an attempt to find the money for payment. “But in the end, they run out of money and the patient will die – not because the treatment doesn’t work, but just because they can’t afford it. “This lack of dialysis treatment is one of the big health inequities around the world.” The new funding will take the product through clinical trials to test how effective it will be as a low cost, low-carbon-footprint alternative to current dialysis. “We think that, while we are mainly aiming for people who are missing out in the poorest countries in the world, the opportunity to reduce the carbon footprint by a factor of 20 means that our system might be very attractive to Australian patients as well,” says Knight. <h2>How does dialysis work?</h2> Normally, a kidney filters out salts, waste and fluids from the blood, which will be excreted from the body as urine. A dialysis machine mimics this process. First, the machine slowly draws out blood from the body using a catheter. Then, a special fluid called dialysate is mixed with the blood to filter the waste products. The dialysate comes in a bag and is made of extra minerals and electrolytes – salts and sugars – and bicarb soda mixed with purified water. Any excess is washed down the drain with blood waste products. The newly cleaned blood is then pumped back into the body. Depending on the person, this needs to be done 3–5 times every 24 hours and can take up to 40 minutes each time. Every session requires a new bag of dialysate, which contributes to the huge cost of treatment. The only way to get the bags is pre-filled and delivered to your door – four bags a day can be up to 2 litres/2 kilograms, or 240kg of fluid delivered per month. The distance delivery trucks must travel to deliver monthly dialysate bags contributes to a high carbon footprint. <h2>The Ellen Medical Dialysis System</h2> Many good ideas come about because of simple competitions. “As a research institute we recognise this medical need, and we ran a global competition called the affordable balances prize,” says Knight. “We had entries from all over the world, and the [dialysis] technology that we’re developing [now] was the prize-winning entry.” The inventor and prize winner, Vincent Garvey, was working on domestic appliances in Shanghai when he came up with the idea and its underlying concept: instead of looking to complicated medical technology, why not model it on everyday items? “The concept is very, very simple,” says Knight. “The distiller that makes pure water [for the dialysate] is basically like a kettle on your kitchen bench to boil water for a cup of tea. “It’s got a few extra bells and whistles, but the technology is really like that of a kettle. We can mass produce it for the same sort of price as you might expect to pay for a good quality kettle in [an appliance store].” The second part of this innovation is bags that can be filled from home using the purified ‘kettle’ dialysate, instead of being frequently delivered pre-filled. “Our approach to manufacturing the bags is less like high-tech med manufacturing and more like food manufacturing,” says Knight. “The bags basically [just have] salt and sugar in them. So, if you think of how much it costs to make a bag of chips or a bag of pretzels, that’s the kind of manufacturing cost we’re looking at. “A very high volume, mass produced, very low unit cost. We think they’re going to come in between five and 10 times less than current dialysis systems.” <h2>Saving lives and saving the planet</h2> The staggering price drop is essential for equitable dialysis globally but filling the bags from home could also dramatically reduce the carbon footprint of dialysis treatment. “Currently in Australia, delivering four bags a day to the patient’s home already filled with fluid works out that each patient needs three tonnes of fluid delivered to their home [each year] so they can do the dialysis at home three times [a day],” explains Knight. “All of the bags for Australia and New Zealand are made in one factory in Western Sydney. That’s fine if you live in Paramatta because the truck can bring you the bags once a month. “But if you live in Perth or in Auckland, then those three tonnes of fluid have to be taken by truck from [Western Sydney] to your home. That carbon footprint, each year, is huge. “Our bags were delivered for 20 times less, so our carbon footprint is going to be 20 times less than current systems. “We’re very proud of that.” Image credits: Getty Images  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=169106&title=At-home+dialysis+for+the+cost+of+a+bag+of+chips" alt="" width="1" height="1" />  </div> <div id="contributors"> This article was originally published on <a rel="noopener" href="https://cosmosmagazine.com/health/medicine/at-home-dialysis-for-the-cost-of-a-bag-of-chips/" target="_blank">cosmosmagazine.com</a> and was written by Deborah Devis. </div> </div>

How to make roads with recycled waste, and pave the way to a circular economy

It cost <a href="https://www.buildingfortomorrow.wa.gov.au/projects/russell-road-to-roe-highway/">A$49 million</a> to add 12.5 kilometres of extra lanes to Western Australia’s Kwinana Highway, south of Perth’s CBD. That’s not unusual. On average, building a single lane of road costs about about <a href="https://www.bitre.gov.au/sites/default/files/rr148.pdf">A$5 million per kilometre</a>.

The<a href="https://www.awe.gov.au/sites/default/files/documents/national-waste-policy-action-plan-2019.pdf"> National Waste Policy</a> agreed to by federal, state and territory governments has a target of 80% resource recovery by 2030. It’s currently <a href="https://www.awe.gov.au/sites/default/files/documents/sustainable-procurement-guide.pdf">about 40%</a>. Of the 74 million tonnes of waste <a href="https://www.environment.gov.au/system/files/pages/5a160ae2-d3a9-480e-9344-4eac42ef9001/files/national-waste-report-2020.pdf">generated in Australia in 2020</a>, masonry materials comprised about 22.9 million tonnes. Plastics, by comparison, comprised about 2.5 million tonnes. Of the 61.5 million tonnes of “core waste” managed by the waste and resource recovery sector, 44% (27 million tonnes) came from the construction and demolition sector, compared with 20% (12.6 million tonnes) from households and local government activities. Most of this waste – concrete, brick, steel, timber, asphalt and plasterboard or cement sheeting – could be reused or recycled. It ends up in landfill due to simple economics. It’s cheaper to buy new materials and throw them away rather than reuse and recycle. Changing this equation and moving to a circular economy, in which materials are reused and recycled rather than discarded in landfill, is a key goal to reduce the impact of building and construction on the environment, including its contribution to climate change. <h2>The economics of ‘externalities’</h2> The fact it is more “economic” to throw materials away than reuse them is what economists call a market failure, driven by the problem of “externalities”. That is, the social and environmental costs of producing, consuming and throwing away materials is not reflected in the prices charged. Those costs are instead externalised – borne by others. In such cases there is a legitimate – and necessary – role for governments to intervene and correct the market failure. For an externality such as carbon emissions (imposing costs on future generations) the market-based solution favoured by most economists is a carbon price. For construction material waste, governments have a few more policy levers to help create a viable market for more recycling. <h2>Using procurement policies</h2> One way to make recycling more attractive to businesses would be to increase the cost of sending waste materials to landfill. But this would likely have unintended consequences, such as illegal dumping. The more obvious and effective approach is to help create more demand for recycled materials through government procurement, adopting policies that require suppliers to, for example, use a minimum amount of recycled materials. With enough demand, recyclers will invest in further waste recovery, reducing the costs. Lower costs in turn create the possibility of greater demand, creating a virtuous circle that leads to a circular economy. <hr /> <a href="https://images.theconversation.com/files/432794/original/file-20211119-17-19fvngo.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/432794/original/file-20211119-17-19fvngo.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Diagram of the circular economy" /></a> <a href="https://www.awe.gov.au/sites/default/files/documents/sustainable-procurement-guide.pdf" class="source">Australian Government, Sustainable Procurement Guide: A practical guide for Commonwealth entities, 2021</a> Australia’s federal, state and territory governments all have sustainable procurement policies. The federal <a href="https://www.environment.gov.au/system/files/resources/856a1de0-4856-4408-a863-6ad5f6942887/files/sustainable-procurement-guide.pdf">Sustainable Procurement Guide</a> states the Australian government “is committed to transforming Australia’s waste into a resource, where most goods and services can be continually used, reused, recycled and reprocessed as part of a circular economy”. But these policies lack some basic elements. <h2>Three key market-making reforms</h2> Our research suggests three important reforms could make a big difference to waste market operations. This is based on interviewing 27 stakeholders from the private sector and government about how to improve sustainable procurement. First, government waste policies that set aspirational goals are not supported by procurement policies setting mandatory minimum recycled content targets. All contractors on government-funded construction projects should be required to use a percentage of recycled waste materials. Second, the nature of salvaging construction materials means quality can vary significantly. Cement recycled from a demolition site, for example, could contain contaminants that reduce its durability. Governments can help the market through regularly auditing the quality of recycler’s processes, to increase buyer confidence and motivate suppliers to invest in production technologies. Third, in some states (such as Western Australia) the testing regimes for recycled construction products are more complex than that what applies to raw materials. More reasonable specifications would reduce compliance costs and thereby the cost of using recycled materials.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/164997/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/salman-shooshtarian-693412">Salman Shooshtarian</a>, Research Fellow, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/savindi-caldera-1187623">Savindi Caldera</a>, Research Fellow and Project Development Manager, Cities Research Institute, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/tayyab-maqsood-711277">Tayyab Maqsood</a>, Associate Dean and Head of of Project Management, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/tim-ryley-1253269">Tim Ryley</a>, Professor and Head of Griffith Aviation, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Kate Middleton stuns in recycled dress for Earthshot awards

Image: Getty The Duke and Duchess of Cambridge have walked the green carpet in London for the first ever Earthshot Prize awards ceremony. Established by Prince William, this prize recognises those who have set up projects that help the environment and combat climate change. Celebrities including Emma Watson, David Attenborough, Ed Sherran, Emma Thompson and Coldplay either presented awards or performed. Attending guests were asked to “consider the environment” when choose an outfit. Kate Middletown stunned the crowd in a recycled Alexander McQueen dress she had previously warn to the BAFTA dinner in 2011. William worn a velvet green suit he had been seen in back in 2019. The couple arrived in an electric car, ditching the usual royal fleet of Range Rovers. The Earthshot Prize offers winners a huge £1 million ($1.8million AUD) cash prize to fund and scale-up their environmental projects. There are five categories: <ul> <li>Protect and restore nature.</li> <li>Clean our air.</li> <li>Revive our oceans.</li> <li>Build a waste-free world.</li> <li>Fix our climate.</li> </ul> Winners of the inaugural event include a food waste hub in Milan and the nation of Costa Rica, which is pioneering a project to pay people to restore natural ecosystems. Among the judges were Sir David Attenborough, Cate Blanchett and singer Shakira. A Sydney team behind the ‘Living Seawalls’ project was among the list of nominees selected in the oceans category. In a short, pre-recorded video played to the crowd, William said: “We are alive in the most consequential time in human history.” “The actions we choose or choose not to take in the next 10 years will determine the fate of the planet for the next 1000,” he said. “Many of the answers are already out there,” he added. “But we need everyone, from all parts of society to raise their ambition and unite in repairing our planet.” The ceremony comes days ahead of the COP26 UN Climate Change Conference in Glasgow, which begins October the 31st.

Woolworths shopping bag hack goes VIRAL

A Woolworths hack for storing the supermarket's plastic grocery bags has ignited a debate with checkout workers. A Gold Coast mum revealed how she folded bags into convenient "triangles". The folding technique is more space-efficient as it means you can keep several in your bag. <img style="width: 0px; height:0px;" src="https://oversixtydev.blob.core.windows.net/media/7841704/food-1.jpg" alt="" data-udi="umb://media/322d914984ff4df0b190cc03d9dbc63a" /> <div class="post_body_wrapper"> <div class="post-body-container"> <div class="post_body"> <div class="body_text redactor-styles redactor-in"> The 20-second video started a debate with check-out workers who said that the hack was "frustrating". “As a cashier, please make sure to unfold them before you get to the checkout because it takes so much time trying to open these,” the Woolies worker wrote. She added: “Sometimes I shake it open aggressively so they’ll know I’m annoyed.” “I would rather give them a bag for free than deal with this,” another worker wrote. A third agreed, saying: “Yes agreed! I’m a cashier too and they’re just so fidgety to unravel and time-consuming.” <blockquote style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" class="instagram-media" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CPzzcWDH5J1/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="13"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"></div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"></div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"></div> </div> </div> <div style="padding: 19% 0;"></div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"></div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" rel="noopener" href="https://www.instagram.com/p/CPzzcWDH5J1/?utm_source=ig_embed&utm_campaign=loading" target="_blank">A post shared by nita 🤎 (@itsnitanita)</a> </div> </blockquote> The poster who made the video said that she didn't expect it to be that popular.

Pack your bags: The trans-Tasman bubble is officially open

Set your sights on New Zealand, as our kiwi neighbour welcomes Aussie travellers once again. The trans-Tasman bubble has officially opened, allowing visitors to fly between the two countries without needing to quarantine before or after travel. Andrew Waddel, Tourism New Zealand’s General Manager, told Today there would be “emotional scenes” in New Zealand today as friends and families reunite following border closures last March. <blockquote style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" class="instagram-media" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CNT6ru9AGpx/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="13"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"></div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"></div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"></div> </div> </div> <div style="padding: 19% 0;"></div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"></div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" rel="noopener" href="https://www.instagram.com/p/CNT6ru9AGpx/?utm_source=ig_embed&utm_campaign=loading" target="_blank">A post shared by New Zealand (@purenewzealand)</a> </div> </blockquote> “Building from that, there are going to be business travellers and holiday arrivals,” Mr Waddel said. “New Zealand gets to welcome back our Australian friends and vice-versa, New Zealanders coming back to Australia as well.” It’s been a long time coming, but Mr Waddel said, “We’re really excited. It’s a great buzz here in the airport.” As well as seeing family and friends reunite, the trans-Tasman bubble would also offer a large economic return and create jobs according to Mr Waddel. He recommended that Australians eager to travel to “plan ahead” and do their research ahead of their trip. “We’re encouraging people to visit websites like New Zealand.com or COVID19.gov.nz and they’ll provide good travel advice,” he said. “Download the COVID app, plan ahead and have contingencies in place as well.” “There’s so much to offer … which we’re looking forward to sharing soon.

Sydney mum’s unbelievable find in lettuce bag

A Sydney mum has taken to Facebook to show her unexpected find in a bag of lettuce she claims she purchased at ALDI. Lesley Khun warned others on the Mosman Living group to "check packed lettuce carefully!" "Last night my son found this baby white headed snake in with the packaged baby cos lettuce he purchased from Aldi," Khun wrote. <img style="width: 500px; height: 281.25px;" src="https://oversixtydev.blob.core.windows.net/media/7840717/cos-lettuce-1.jpg" alt="" data-udi="umb://media/ab4ef30453e44af1a0970a35ac96bc3f" /> "Make sure you check packed lettuce carefully!" When asked by group members what fate the snake had met, Khun revealed that WIRES Wildlife Rescue had come to remove the creature. White headed snakes are thankfully not too common in Brisbane, and are also not considered dangerous to humans. <img style="width: 0px; height: 0px;" src="https://oversixtydev.blob.core.windows.net/media/7840716/cos-lettuce-2.jpg" alt="" data-udi="umb://media/a4b27bb2496549c2a9e151d47466daf3" /> "Oh my Lord!" one person wrote on the post. Another user commented: "Allens taking Snakes Alive to a whole new meaning."
