Using sunlight to recycle black plastics

"Simple, visible light irradiation holds the potential to transform the chemical recycling of plastics..."

27-Nov-2024 - Not all plastics are equal — some types and colors are easier to recycle than others. For instance, black foam and black coffee lids, which are often made of polystyrene, usually end up in landfills because color additives lead to ineffective sorting. Now, researchers report in ACS Central ...

Plastic-eating bacteria turn waste into useful starting materials for other products

Microbial Upcycling of Waste PET

03-Nov-2023 - Mountains of used plastic bottles get thrown away every day, but microbes could potentially tackle this problem. Now, researchers in ACS Central Science report that they’ve developed a plastic-eating E. coli that can efficiently turn polyethylene terephthalate (PET) waste into adipic acid, which ...

A popular compostable plastic doesn’t break down in the ocean

“Biodegradable” is a misleading term for plastic substitutes that require heat to break down or industrial compositing conditions

26-May-2023 - A widely used compostable plastic persists unchanged in marine environments for at least 14 months, according to a new study in PLOS ONEby Sarah-Jeanne Royer andcolleagues from Scripps Institution of Oceanography at theUniversity of California, San Diego.The study highlights the distinction ...

Researchers recycles previously unrecyclable plastic

U-Michigan team discovered a way to chemically recycle PVC into usable material

06-Dec-2022 - PVC, or polyvinyl chloride, is one of the most produced plastics in the United States and the third highest by volume in the world. PVC makes up a vast amount of plastics we use on a daily basis. Much of the plastic used in hospital equipment—tubing, blood bags, masks and more—is PVC, as is most ...

A sea change for plastic pollution: new material biodegrades in ocean water

Marine microorganisms found to feast on new polyurethane materials used in a startup's sustainable shoes

26-Sep-2022 - Plastics, now ubiquitous in the modern world, have become a rising threat to human and environmental health. Around the planet, evidence of plastic pollution stretches from grocery bags in the deep sea to microplastics in our food supplies and even in our blood. Seeking solutions to counteract ...

Catalytic deconstruction of PET with zirconium metal–organic framework

11-May-2022 - Polyethylene terephthalate (PET) is one of the most common plastics. Discarded PET most often ends up in landfills or in the environment because the rate of recycling remains low. In the journal Angewandte Chemie, a research team has now reported a zirconium-based metal–organic framework material ...

Chemists develop radical way to make it easier, more profitable to recycle plastic

By modifying carbon-hydrogen bonds, chemists transform plastic trash into tougher, stronger material

09-Feb-2022 - The United States generates more plastic trash than any other country – about 46.3 million tons of it -- or 287 pounds per person a year,according to a 2020 study. The country’s 9% rate of recycling will never keep up. Why so low? The chemistry of today’s plastics makes most difficult to ...
