Sep. 4, 2024 Chemists have developed a catalytic process that turns the largest component of today's plastic waste stream, polyolefin plastic bags and bottles, into gases -- propylene and isobutylene -- that ...
Sep. 29, 2022 Polyethylene plastics -- single-use bags and general-purpose bottles -- are indestructable forever plastics. That also makes them hard to recycle. Chemists have found a way to break down the polymer ...
Nov. 4, 2024 Bio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. ...
Feb. 13, 2025 The possibilities for material design and production of plastic components are being expanded through 3D printing technology. However, there is a shortage of recyclable polymers that meet the ...
Nov. 28, 2022 Researchers have devised a method to transform post-consumer mixed plastics that wash up on beaches into a variety of valuable ...
Apr. 26, 2023 Polymer chemists have been finding ways to tackle the environmental problems humans have created with plastics waste. Now, a team has come up with fundamental new chemistry that seeds a creative ...
Sep. 6, 2022 If you own a retro gaming console or have an old roll of packing tape, you've seen how plastics turn yellow as they age. Though the cause of this color change has long been attributed to the ...
Jan. 29, 2025 This startling mechanism for promoting depolymerization relies on an additive that many plastics already contain: a pigment called carbon black that gives plastic its black color. Through a process ...
Aug. 23, 2022 Wind power is an increasingly popular form of renewable energy. But when it's time to replace the huge turbine blades that convert wind into electricity, disposal is a problem. Today, scientists ...
July 11, 2023 Researchers have studied the global trade in highly hazardous chemicals subject to a global treaty -- the Rotterdam Convention. The results are sobering: Nearly half of the total trade volume of ...
