The logger who learned the value of living trees
2024-09-28, BBC News
https://www.bbc.com/future/article/20240927-the-logger-who-learned-the-value-...

[Robert] Brito and his family, who live along the Rio Negro in the Brazilian Amazon, only saw the monetary value of logged trees. Now, when Brito looks at a tree, everything has changed. "We stopped thinking about price and started thinking about [a different kind of] value. For example, when I see a beautiful cumaru [Brazilian teak] tree, 300 to 400 years old ... I still touch it, but with a different mindset. I have access to education, technology, a future for the young people living here, and I still contribute to the preservation of our planet in relation to climate change." Brito's transition ... required the support and alignment of financial, social and environmental incentives. In 2008, the government of the Brazilian state of Amazonas created the Rio Negro Sustainable Development Reserve, in order to preserve nature and to support communities living within it. The designation of the sustainable development reserve led to organisations including the Foundation for Amazon Sustainability (FAS) establishing education and health projects there. Brito recalls that one day Virgilio Viana, the director general of FAS, suggested that he might like to work in community-based tourism. "I started receiving people in my own home," Brito says. This trial was a success. He realised that he earned more in a week than he had ever seen in three months of logging. In 2011 – three years after the creation of the sustainable development reserve and over two decades since he cut down his first tree – Brito opened his nature lodge. And he put down his chainsaw. Moving away from blaming or shaming individuals can bring more people into the environmental movement. So can valuing people's prior experiences, such as Brito drawing on his decades of logging as he guides visitors around the forest in his flip-flops.

The Farmers Abandoning Big Ag to Grow Mushrooms and Herbs
2024-09-17, Reasons to be Cheerful
https://reasonstobecheerful.world/farmers-quitting-factory-farming-transfarma...

Leah Garcés considered Craig Watts her enemy. As CEO and president of the nonprofit Mercy for Animals, Garcés has devoted her life to protecting animals. When she met Watts in the spring of 2014 at his poultry farm in North Carolina, he was one those factory farmers she deeply despised. Watts had raised over 720,000 chickens in 22 years for Perdue, the fourth-largest chicken company in the US. He took out a $200,000 bank loan to build four giant chicken houses. Squeezed by Perdue’s profit margins, Watts struggled to pay the bills. Garcés realized that Watts was not her enemy, but an ally: Chicken farmers like him wanted to end chicken farming as much as she did. Yet because of his hefty loans, Watts saw no way out. Together, they released footage from the horrors of chicken farming in the New York Times. Watts has now become one of the poster farmers for the Transfarmation Project, which Garcés founded as an offshoot of the nonprofit Mercy for Animals in 2019. Ultimately, Garcés’s vision is not just “helping a few dozen farmers transition to a healthier and more sustainable model, it is about how we transition away entirely from factory farming.” The Transfarmation Project connects farmers with consultants and is producing resources and pilots to model successful transitions. In the same warehouse where Watts once had to kill chickens and where he and Garcés filmed the whistleblower video, he is now harvesting mushrooms.

Turning Brownfields to Blooming Meadows, With the Help of Fungi
2024-06-27, Yale Environment 360
https://e360.yale.edu/features/danielle-stevenson-interview

Danielle Stevenson ... has been pioneering a nature-based technique for restoring contaminated land, using fungi and native plants to break down toxins like petroleum, plastics, and pesticides into less toxic chemicals. The usual way of dealing with tainted soil is to dig it up and cart it off to distant landfills. In a recent pilot project funded by the city of Los Angeles, Stevenson ... working with a team of UC Riverside students and other volunteers, significantly reduced petrochemical pollutants and heavy metals at an abandoned railyard and other industrial sites in Los Angeles. Stevenson says she believes her bioremediation methods can be scaled up to clean polluted landscapes worldwide. "Decomposer fungi can degrade petrochemicals the same way they would break down a dead tree," [said Stevenson]. "And in doing so, they reduce the toxicity of these petrochemicals and create soil that no longer has these contaminants or has much reduced concentrations of it. They can also eat plastic and other things made out of oil. People who live in a place impacted by pollution need to have a say in how their neighborhood is being cleaned up. We need to empower them with the tools to do this. That’s why along with doing these studies and pilot projects, I’ve been running workforce development programs. Potentially, they could bring economic opportunities and benefits to the community in addition to cleaning up the contaminated site."

To Keep Clean Drinking Water Flowing to Paris, Farmers Are Going Organic
2024-06-25, Reasons to be Cheerful
https://reasonstobecheerful.world/paris-organic-farming-clean-water-supply/

About 100 miles southeast of Paris ... a charming stone aqueduct cuts across the green fields. “That’s the Aqueduct of the Vanne,” says [farmer] Zoltan Kahn. The Vanne, which supplies a fifth of Paris’s tap water, is fed by the water sources in these parts. The region is rich in biodiversity and has been a key drinking water catchment area for centuries. Since 2020, Eau de Paris, the city’s public water service, has been supporting farmers near its watersheds ... to reduce the use of pesticides and fertilizers on their crops. In other words, to go organic. When Kahn was approached by Eau de Paris with support to go fully organic, he jumped at the opportunity. In exchange for switching to organic, he would receive a so-called “Payment for Environmental Services” for each hectare of his farmland. As part of the €48 million ($51.8 million) project, Eau de Paris and the Seine-Normandy Water Agency, a public institution fighting water pollution in the region, are supporting 115 farmers based in watersheds that supply the city to either reduce their use of chemicals or go fully organic (as 58 percent of the farmers have). Already €32 million of that funding has been granted, according to Anne-Sophie Leclere, deputy director general of Eau de Paris. “It’s better for us to have cleaner, purer watersheds,” says Leclere. “This will save Paris from having to pay much more to process the water once it arrives in the city.”

How Philadelphia Is Giving Fallen Trees New Life
2024-06-24, Reasons to be Cheerful
https://reasonstobecheerful.world/philadelphia-reforestation-hub-carbon-smart...

Each year, US cities lose an estimated 36 million trees to development, disease and old age, many of which ultimately end up in landfills. Losing these urban trees — known to help cool their neighborhoods, lower carbon emissions and improve mental health, among other benefits — costs an estimated $96 million annually. In Philadelphia, a partnership is giving the City of Brotherly Love’s fallen trees new life. Philadelphia Parks & Rec joined forces with Cambium Carbon, a Washington, D.C.-based startup that repurposes waste wood, and PowerCorpsPHL, a local nonprofit that creates job opportunities for unemployed and under-employed 18- to 30-year-olds, to launch the Reforestation Hub. Rather than sending trees straight to the landfill or the city’s organic recycling center to simply become mulch or wood chips, the Reforestation Hub (which is co-located in the city’s organic recycling center) will salvage as many trees as it can. As many as possible will be turned into Cambium’s Carbon Smart Wood, which stores 5.23 pounds of carbon in each board foot. Fifteen percent of sales that come out of the hub will be donated to Tree Philly at the end of each year to support tree planting and maintenance across the city. While the hub formally launched only recently, in the year and a half that it’s taken to get the infrastructure in place, it has already diverted 542 logs to create 28,000 board feet of Carbon Smart Wood.

Denmark’s Radical Plan for a Plant-Based Future
2024-06-17, Reasons to be Cheerful
https://reasonstobecheerful.world/denmark-radical-plan-plant-based-future/

Trine Krebs is sometimes called “the leek woman,” or even Miss Dry-Legume, of Denmark. The 48-year-old has for decades traveled around the country as, in her words, a “food inspirer,” proselytizing about all things vegetables. So when, in October 2023, the Danish government published the world’s first ever national action plan for shifting towards plant-based diets, Krebs was ecstatic. The Danish government has three main goals: to increase demand for plant-based foods, to develop supply for plant-based foods, and to improve how all the different stakeholders — from scientists to farmers and chefs, food sociologists, and nutrition experts — in this nascent domestic industry are working together. Danish authorities see reducing meat and dairy consumption as key to reaching the Nordic state’s goal of cutting carbon emissions by 70 percent before 2030, when compared to 1990. The climate think tank Concito estimates that more than half of Denmark’s land is used for farming and that agriculture accounts for about a third of its carbon emissions. Yet a published in 2021 found that the emissions made by producing plant-based foods are roughly half the amount incurred by meat production. Denmark believes ... that the necessary shift toward plant-based eating also offers a massive economic opportunity. If the country were to gain a three percent share of the global plant-based food market, it could create up to 27,000 jobs.

Planetary health diet cuts early death risk, new study shows
2024-06-10, Washington Post
https://www.washingtonpost.com/wellness/2024/06/10/planetary-diet-lower-morta...

Can you eat a diet that’s good for your health and good for the planet? A new study suggests that it’s possible. It found that people who ate mostly minimally processed plant foods such as nuts, beans, fruits, vegetables, whole grains and olive oil, along with modest amounts of meat, fish, eggs and dairy, had lower rates of premature death from heart disease, cancer and other chronic diseases. At the same time, their diets had a smaller environmental footprint because they consisted of foods that were grown using relatively less land and water and that were produced with fewer greenhouse gas emissions. The study ... was inspired by a landmark 2019 report from the EAT-Lancet Commission, which designed a “Planetary Health Diet” capable of sustaining 10 billion people and the planet by 2050. The planetary health diet, in broad strokes, encourages people to eat more plants and whole foods alongside small portions of meat and dairy. People whose eating habits most closely adhered to the planetary health diet were 30 percent less likely to die prematurely compared to people who ate the lowest amounts of foods that form the basis of the planetary health diet. Planetary health eaters had a 10 percent lower risk of dying from cancer, a 14 percent lower likelihood of dying from cardiovascular diseases, a 47 percent reduction in the risk of dying from lung disease, and a 28 percent lower likelihood of dying of Alzheimer’s disease and other neurodegenerative disorders.

How Electric Harps Are Protecting Honey Bees
2024-05-23, Reasons to be Cheerful
https://reasonstobecheerful.world/electric-harps-protect-honey-bees-from-asia...

Michel Costa had become a frustrated veteran of an obscure yet devastating war in Europe. The enemy: invasive Asian hornets, which had been massacring his honey bees. When Costa, a retiree and avid beekeeper, discovered a new weapon with the potential to change the course of the entire war, he was intrigued. Several companies had begun selling so-called “electric harps,” which they claimed could kill the hornets in droves by electrocuting them as they flew through. Although the harps take different forms, each one is made of some sort of large frame, which is then “strung” with conductive metal wires. These are then connected to a source of electricity, often solar panels, so that the wires conduct simultaneously positive and negative charges. When a hornet flies through, its wings touch the wires on either side, completing a circuit, and thereby delivering a fatal current of electricity. Beekeepers then place the harps around their hives in positions along the hornets’ frequent flight paths. The harps can reduce predation pressure by 89 percent — enough to give hives the chance to replenish their stores. In one study only 56 percent of unprotected hives survived through winter, while 78 percent of those protected by harps did. Harps are also cheaper than other methods for beekeepers to install and operate. Beekeepers can buy them in complete kits that cost around $300 ... as Costa did. When combined with solar panels, maintenance costs are minimal.

The all-female patrol guarding Ecuador's Amazon Rainforest
2024-05-07, BBC News
https://www.bbc.com/future/article/20240503-the-indigenous-women-fighting-min...

It is the break of dawn in the Serena community, in the middle of the Ecuadorian Amazon. Elsa Cerda, a 43-year-old indigenous Kichwa woman, brews guayusa leaves – a native plant from the rainforest – in a pot. It marks the start of the Guayusa Upina, a ritual performed by Amazonian indigenous peoples before beginning their daily activities. This tradition is more than a routine; it's a spiritual connection to their ancestral roots. As the first rays of light begin to filter through the tree canopy, a diverse assembly of 35 women, ranging from 23 to 85 years old, arrives one by one at the ceremony. The group goes by the name of "Yuturi Warmi". Their role as Amazonian guardians involves safeguarding the territory from pollution and preserving the land and rivers from activities that jeopardise biodiversity – such as deforestation and mining operations. The women undergo regular training sessions, with younger women teaching older members how to operate these phone cameras and drones. Each patrol involves a rotation of members, particularly the younger ones, who primarily patrol the land, ensuring continued presence and surveillance. The women do not carry any weapons, relying instead on their collective presence to act as a deterrent. In the event of witnessing illegal mining activities, the women prioritise non-violent measures such as contacting the authorities and gathering evidence.

Plastic-eating bacteria can help waste self-destruct
2024-04-30, BBC News
https://www.bbc.com/news/science-environment-68927816

Scientists have developed a "self-digesting plastic", which, they say, could help reduce pollution. Polyurethane is used in everything from phone cases to trainers, but is tricky to recycle and mainly ends up in landfill. However, researchers have come up with a sci-fi like solution. By incorporating spores of plastic-eating bacteria they've developed a plastic that can self-destruct. The spores remain dormant during the useful lifetime of the plastic, but spring back to life and start to digest the product when exposed to nutrients in compost. There's hope "we can mitigate plastic pollution in nature", said researcher Han Sol Kim, of the University of California San Diego, La Jolla. And there might be an added advantage in that the spores increase the toughness of the plastic. "Our process makes the materials more rugged, so it extends its useful lifetime," said co-researcher, Jon Pokorski. "And then, when it's done, we're able to eliminate it from the environment, regardless of how it's disposed." The plastic is currently being worked on at the laboratory bench but could be in the real world within a few years, with the help of a manufacturer, he added. The type of bacteria added to the plastic is Bacillus subtilis, widely used as a food additive and a probiotic. Crucially, the bacteria has to be genetically engineered to be able to withstand the very high temperatures needed to make plastic.

Watch these hungry waxworms eat through plastic and digest it too
2024-04-24, BBC News
https://www.bbc.com/future/article/20240419-the-worms-that-eat-through-plastic

At first glance there's nothing particularly remarkable about waxworms. The larval form of wax moths, these pale wriggling grubs feed on the wax that bees use to make their honeycomb. For beekeepers, the pests are something to swiftly get rid of without a second thought. But in 2017 molecular biologist Federica Bertocchini ... stumbled on a potentially game-changing discovery about these creatures. Bertocchini, an amateur beekeeper, threw some of the waxworms in a plastic bag after cleaning her hive, and left them alone. A short time later, she noticed the worms had started producing small holes in the plastic, which begun degrading as soon as it touched the worms' mouths. The worms were doing something that we as humans find remarkably difficult to do: break down plastic. Not only that, but the worms appeared to be digesting the plastic as though it was food. Bertocchini and her fellow researchers began collecting the liquid excreted from the worms' mouths. They found this "saliva" contained two critical enzymes, Ceres and Demeter – named after the Roman and Greek goddesses of agriculture, respectively – which were able to oxidise the polyethylene in the plastic, essentially breaking down that material on contact. Bertocchini is now chief technology officer at bioresearch startup Plasticentropy France, working with a team to study the viability of scaling up these enzymes for widespread use in degrading plastic.

German hospitals serve planetary health diet
2024-03-28, The Guardian (One of the UK's Leading Newspapers)
https://www.theguardian.com/environment/2024/mar/28/planetary-health-diet-mea...

Patrick Burrichter did not think about saving lives or protecting the planet when he trained as a chef. But 25 years later he has focused his culinary skills on doing exactly that. On the outskirts of Berlin, Burrichter and his team cook for a dozen hospitals that offer patients a “planetary health” diet – one that is rich in plants and light in animals. Compared with the typical diet in Germany, known for its bratwurst sausage and doner kebab, the 13,000 meals they rustle up each day are better for the health of people and the planet. In Burrichter’s kitchen, the steaming vats of coconut milk dal and semolina dumpling stew need to be more than just cheap and healthy – they must taste so good that people ditch dietary habits built up over decades. The biggest challenge, says Burrichter, is replacing the meat in a traditional dish. Moderate amounts of meat can form part of a healthy diet, providing protein and key nutrients, but the average German eats twice as much as doctors advise. Patients on the wards of Waldfriede praise the choice of meals on offer. Martina Hermann, 75, says she has been inspired to cook more vegetables when she gets home. Followers of the planetary health diet need not abandon animal products altogether. The guidelines, which were proposed by 37 experts from the EAT-Lancet Commission in 2019, translate to eating meat once a week and fish twice a week, along with more wholegrains, nuts and legumes.

Toward truly compostable plastic
2024-02-27, Knowable Magazine
https://knowablemagazine.org/content/article/technology/2024/compostable-plas...

Humans have created 8 billion metric tons of plastic. More than half the plastic ever produced —some 5 billion metric tons — lies smeared across the surface of the Earth. Chemists were creating “synthetic” plastics decades before the oil industry took off, from, among other materials, waste oat husks and vegetable oil. One of the tacks toward more sustainable plastics is to turn back to such biological sources. The ideal materials are not just biodegradable but also compostable — a narrower category that indicates the material can break down into organic components that are harmless to plants and animals. Compostability, unfortunately, is not easily achieved. The natural world already supplies promising polymers that are all compostable, says David Kaplan, a biomedical engineer at Tufts University. [Physicist Eleftheria] Roumeli, for example, has mined the promise of algal cells. They’re small, and therefore easily manipulable; they contain large amounts of proteins, which are biological polymers, alongside other useful materials. She and her students took powdered algae and passed it through a hot presser. After several trials ... they found they could produce a material that was stronger than many commodity plastics. The material was also recyclable: It could be ground back to powder and pressed again. If it were to be carelessly tossed into the dirt, the material would break apart at the same rate as a banana peel.

The 3D-Printed Affordable Housing of the Future Will Be Recyclable
2024-01-26, Reasons to be Cheerful
https://reasonstobecheerful.world/future-affordable-housing-3d-printed-recycl...

When you imagine a 3D-printed home, you probably picture a boxy concrete structure. As 3D printing’s popularity has grown in the construction industry — thanks to its efficiency when it comes to time, energy and cost — carbon-intensive concrete has become the go-to building material. But a project in Maine has set its sights on something different: a neighborhood of 600-square-foot, 3D-printed, bio-based houses crafted from materials like wood fibers and bioresins. The aim: a complex of 100-percent recyclable buildings that will provide homes to those experiencing houselessness. In late 2022, an initiative between the University of Maine and local nonprofit Penquis unveiled its prototype — BioHome3D, the first 100-percent recyclable house. Now, the pioneering project is working toward completing its first livable housing complex. It will be fully bio-based, meaning all materials will be derived from living organisms such as plants and other renewable agricultural, marine and forestry materials. As the materials are all 100-percent recyclable, so become the buildings. The materials are also all renewable. And thanks to its natural composition, the home acts as a carbon sink, sequestering 46 tons of carbon dioxide per 600-square-foot unit. The materials for this project will mainly come from wood left over by local mills. “The wood fiber material that’s used in the mix is essentially waste wood here in Maine,” says Jason Bird, director of housing development for Penquis.

Scientists invent dirt-fuelled power source that ‘lasts forever’
2024-01-16, The Independent (One of the UK's Leading Newspapers)
https://www.independent.co.uk/tech/battery-fuel-cell-forever-power-b2479535.html

Scientists have developed a new type of fuel cell that can provide endless power through electricity harvested from dirt. A team from Northwestern University in the US say the book-sized unit could be used to power sensors used in farming, as well as remote devices in the Internet of Things (IoT). The technology works by generating electricity from naturally-occurring bacteria within the soil, offering a sustainable and renewable alternative to toxic and flammable batteries. “These microbes are ubiquitous; they already live in soil everywhere,” said George Wells ... at Northwestern University. “We can use very simple engineered systems to capture their electricity. We’re not going to power entire cities with this energy. But we can capture minute amounts of energy to fuel practical, low-power applications.” The soil-based microbial fuel cell (MFC) is based on a 113-year-old technology first developed by British botanist Michael Cressé Potter, who was the first person to successfully generate electricity from microorganisms. It took until the 21st century for the first commercial applications to be proposed, with Foster’s Brewing using a prototype to convert the yeast in brewery wastewater into electricity. The latest fuel cell was tested in wet and dry conditions to power sensors measuring soil moisture and detecting touch, outlasting the power of similar technologies by 120 per cent.

‘It’s kind of gross but we can do it’: How a community learned to go zero waste
2023-12-07, The Guardian (One of the UK's Leading Newspapers)
https://www.theguardian.com/environment/2023/dec/07/its-kind-of-gross-but-we-...

When [city councillor] Alexandre Garcin dreamed up Zero-Waste Roubaix, it wasn’t sustainability he wanted to tackle, but the litter problem that plagued his city. Garcin sent out leaflets looking for 100 volunteers to participate in a free, year-long pilot programme that would teach them how to live waste-free. These familles zéro déchet, or zero-waste families, would receive training and attend workshops on topics such as making your own yoghurt and cleaning with homemade products, with the goal of halving their waste by the year’s end. Volunteers weren’t offered any direct financial incentives to participate – only the promise of helping solve the litter problem and protecting the environment. The project focused on creating an identity around zero-waste and assigning families quantitative waste-reduction targets – strategies that are proven to be effective in other contexts, and everyone got pretty straightforward guidelines – for example, “don’t buy more food than you can eat”. According to Garcin, it’s actually “not that difficult” to halve a household’s waste production. Composting gets you most of the way there, since organic waste makes up about a third of the average French family’s municipal waste by weight. Another third is glass and metal, a significant chunk of which can probably be kept out of the landfill through recycling, and 10% is plastic, much of which can be avoided by finding reusable alternatives to plastic grocery bags, cutlery, packaging and other single-use items.

Rich Folks Import This Building Material. A Minnesota Tribe Makes Its Own.
2023-12-04, Mother Jones
https://www.motherjones.com/environment/2023/12/minnesota-tribe-mdewakanton-b...

For now, it’s only a gaping hole in the ground. But when construction is complete next April, the Lower Sioux—also known as part of the Mdewakanton Band of Dakota—will have a 20,000-square-foot manufacturing campus that will allow them to pioneer a green experiment, the first of its kind in the United States. They will have an integrated vertical operation to grow hemp, process it into insulation called hempcrete, and then build healthy homes with it. Right now, no one in the US does all three. Once the tribe makes this low-carbon material, they can begin to address a severe shortage of housing and jobs. Recapturing a slice of sovereignty would be a win for the Lower Sioux. They lost most of their lands in the 19th century, and the territory finally allotted to them two hours south of Minneapolis consists of just 1,743 acres of poor soil. That stands in contrast to the fertile black earth of the surrounding white-owned farmlands. Nearly half of the 1,124 enrolled members of the tribe need homes. “The idea of making homes that would last and be healthy was a no-brainer,” said Robert “Deuce” Larsen, the tribal council president. Leading the national charge on an integrated hempcrete operation is no mean feat, seeing that virtually no one in the community had experience with either farming or construction before the five-person team was assembled. Hemp can grow in a variety of climates. What’s more, hemp regenerates soil, sequesters carbon, and doesn’t require fertilizers.

‘You can walk around in a T-shirt’: how Norway brought heat pumps in from the cold
2023-11-23, The Guardian (One of the UK's Leading Newspapers)
https://www.theguardian.com/environment/2023/nov/23/norway-heat-pumps-cold-he...

In most of Europe, fitting a heat pump is one of the most powerful actions a person can take to reduce their carbon footprint. But in Norway, where clean-yet-inefficient electrical resistance heaters have long been common, upgrading to a heat pump is often a purely financial decision. Two-thirds of households in this Nordic country of 5 million people have a heat pump, more than anywhere else in the world. For many years, Norwegians and their neighbours heated their homes with fossil fuels. But during the 1973 oil crisis, when prices shot up, the country’s political leaders made a conscious choice to promote alternatives. “Norway ensured early on that fossil-fuel heating was the most expensive option, making heat pumps cost competitive,” said Dr Jan Rosenow from the Regulatory Assistance Project, a thinktank that works to decarbonise buildings. “They did this by taxing carbon emissions from fossil heating fuels. That’s been the key to incentivise heat pump adoption.” Norway also trained up a workforce to install them. Heat pumps’ efficiency has been increased over decades, partly because of the early adopters in Nordic countries who tinkered away to the point where a modern version can deliver three to five units of heat for every unit of electricity used to power it. An efficient gas boiler, on the other hand, can only produce as much heat as the energy contained in the fuel being burned. A heat pump will have a smaller carbon footprint than a gas boiler even when plugged into an electricity grid.

The EU Just Banned Microplastics. How Are Companies Replacing Them?
2023-11-16, Reasons to be Cheerful
https://reasonstobecheerful.world/microplastics-europe-ban-natural-alternatives/

Microplastics — solid plastic particles up to five millimeters in size that are not biodegradable — are pretty much everywhere. They have been detected in over 1,500 different marine animal species. They also find their way into our bodies via the water cycle and the food chain. In fact, the average person consumes up to five grams of microplastics per week. The European Union has now banned intentionally added microplastics. This applies to plastic glitter or polyethylene particles used as abrasives in scrubs, shower gel and toothpaste (these have been banned in the US since the 2015 Microbead-Free Waters Act). Under the terms of the ban, some products, such as plastic glitter found in creams or eye shadow, have been granted a transitional period to give manufacturers a chance to develop new designs. LUSH and The Body Shop are among the companies that have long been offering natural alternatives, using ground nuts, bamboo, sea salt and sugar. Beiersdorf AG ... has not used microbeads for exfoliation purposes since 2015. Instead, it has used, for example, cellulose particles or shredded apricot kernels. Since the end of 2019, all Beiersdorf wash-off products have been free of microplastics. Before the EU ban, Germany stopped providing public funding for artificial turf pitches with granules containing a high proportion of microplastic. As a result, the country already has hundreds of pitches that are filled with cork and sand instead of microplastics.

‘A treasure beneath our feet’: How the Dutch went down the toilet looking for heat
2023-11-08, The Guardian (One of the UK's Leading Newspapers)
https://www.theguardian.com/environment/2023/nov/08/how-the-dutch-went-down-t...

Dutch sewage waste is being seen as a reliable heat source for millions of homes that the government wants to be unhooked from the country’s gas system by 2050. Lieven de Key, a housing corporation in Amsterdam, is planning what is believed to be the first sewer warmth project that will tap into a main district sewage pipe to warm 1,600 existing social and student homes. “We have a photo of the street covered with snow, and the manhole covers all without snow,” says Jeroen Rademaker, the project leader. “Even when there’s snow in the winter, the sewer is warm. Warm sewage water flows 24 hours a day and we should capture it. This can happen wherever there is a big sewage pipe.” “The warmth comes from showers, the toilet, wastewater from washing, from the dishwasher, from the washing machine,” says Postuma. “Together it all gives, throughout the year, a temperature between 15 and 18 degrees. And we are going to make a bypass around the main sewer, put a heat exchanger around it and bring it to the houses in insulated pipes. We place it in an electric heat pump, and the water is heated up to 60 or 70C – medium temperature.” The heat exchanger transfers that source heat from the drain to a working fluid that can be transported to the buildings without needing to circulate the actual sewage waste. Then the blocks’ heat pumps, fired by solar energy, can amplify that heat in the opposite way to the workings of a refrigerator.
