At a Massachusetts lab, pebble-sized pellets are transformed into forks and films that won't leave persistent microplastics in the environment. https://phys.org/news/2026-08-traditional-plastic-forks-microplastics-sugar.html Environment Mon, 10 Aug 2026 19:20:03 EDT news705587356 The search for leather alternatives has led researchers somewhere unexpected: fungi. Although traditional leather is durable, producing it requires animal agriculture, which carries negative environmental impacts. Meanwhile, vegan alternatives are typically made from petroleum-based plastics that are difficult to recycle. Researchers report in ACS Applied Bio Materials that mycelium, the underground network of fibers below mushroom caps, can be pressed into a durable yet compostable leather-like fabric. They even sewed the fabric into a purse. https://phys.org/news/2026-08-handbag-mushrooms.html Biochemistry Thu, 06 Aug 2026 10:40:06 EDT news705229201 Virginia Tech chemist and chemical engineer Guoliang "Greg" Liu and his lab have developed a process that converts the plastic polyvinyl chloride (PVC) into polyalphaolefin, a key component in lubricants such as engine oil. Published Aug. 5 in the journal Nature, the research could help address two environmental challenges: recycling one of the world's most difficult plastics and producing a valuable industrial material. https://phys.org/news/2026-08-world-difficult-plastics-premium-lubricant.html Polymers Wed, 05 Aug 2026 11:00:07 EDT news705067441 Researchers at Colorado State University have developed a process to transform naturally occurring, highly stable carbon dioxide into recyclable, high-performance materials that could replace today's plastics in many situations.

But once discarded, it is among the hardest materials on Earth to recycle. Most recycling processes require plastics to be sorted by type first, a step that is both labor-intensive and costly. As a result, only 9% of discarded plastic is actually recycled, while 79% is dumped in landfills and another 12% is incinerated, releasing carbon dioxide in the process. https://phys.org/news/2026-07-plastic-hydrogen-fuel.html Materials Science Wed, 15 Jul 2026 10:50:03 EDT news703329171 In an innovative gas fermentation process, reducing the concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic poly[(R)-3-hydroxybutyrate]. Researchers found that hydrogen-oxidizing bacteria grown under safe, nonflammable gas conditions enable more efficient production of biodegradable plastic at lower CO2 levels. The study provides a promising strategy for sustainable carbon recycling and efficient CO2 utilization. https://phys.org/news/2026-07-carbon-dioxide-microbial-production-biodegradable.html Materials Science Tue, 14 Jul 2026 21:40:04 EDT news703241788 Ever wondered where your plastics end up? A PET bottle can be washed, shredded, melted and given a second life. But most everyday items—toys, mattresses, car seats—are made from different plastics that refuse to mix when melted, producing unusable, contaminated material. Sorting is difficult and expensive, so most mixed plastic waste ends up burned or buried, and the materials are lost for good. https://phys.org/news/2026-07-catalyst-plastic-recyclable-chemical.html Polymers Thu, 09 Jul 2026 18:00:06 EDT news702801769 The research group of Professor Kotohiro Nomura, Tokyo Metropolitan University, in cooperation with the research groups of Senior Researcher Hiroshi Hirano and Director Seiji Higashi of the Osaka Research Institute of Industrial Science and Technology, and Associate Professor Hiroki Takeshita of The University of Shiga Prefecture, has developed biobased poly(ester amide)s from inedible biorenewables that can be easily chemically recycled and exhibit better mechanical (tensile) properties in film than commodity plastics. https://phys.org/news/2026-07-biobased-polymers-excellent-tensile-properties.html Polymers Tue, 07 Jul 2026 00:00:02 EDT news702538064 In the world of market competition, having the best and brightest package could send company sales into the millions.

New research from Washington State University shows that recycling could be a feasible alternative, reducing reliance on fossil fuels and keeping plastics out of the waste stream. https://phys.org/news/2026-06-dirty-farm-plastic-cleaner-mulch.html Environment Mon, 01 Jun 2026 12:00:06 EDT news699529767 The textile industry produces a substantial portion of the world's waste, with only about 12% of fiber materials ending up in recycling. Textiles also account for much of the microplastics in oceans. During every wash cycle, synthetic fibers shed microplastics that are flushed down the drain and eventually enter aquatic environments. Increasing textile recycling alone won't solve this problem because most petrochemical-based fibers are difficult to recycle and continue to release persistent microplastics throughout their life cycle. https://phys.org/news/2026-05-recyclable-protein-textiles-microplastic-pollution.html Materials Science Sat, 16 May 2026 11:00:04 EDT news697991435 A new University at Buffalo study finds that people in the United States generate similar amounts of plastic packaging waste regardless of income, education level or where they live. Yet wealthier and more college-educated communities are much more likely to recycle soda bottles, takeout containers and other plastic packaging. Why? It's complicated, but the study, published in Communications Sustainability, suggests that unequal access to recycling infrastructure plays a key role. https://phys.org/news/2026-04-doesnt-recycle-plastic-lack-access.html Environment Wed, 08 Apr 2026 05:00:03 EDT news694795321 A breakthrough method for chemically recycling acrylic—one of the world's most widely used plastics—has been developed by researchers at the University of Bath.
