Breakthrough in creating a fully biodegradable, algae-based plastic
Biodegradable plastics, a long-sought solution to the global plastic pollution crisis, have taken a major leap forward with a new development from Cornell University. Researchers have successfully created a bio-based plastic that completely degrades in compost within a few weeks. This breakthrough could revolutionize the way we manufacture and dispose of plastic products, potentially reducing the environmental impact of plastic waste.
The newly developed plastic is made from PHAs (polyhydroxyalkanoates), a naturally occurring polymer produced by microorganisms. Unlike traditional plastics derived from fossil fuels, PHAs are fully biodegradable, breaking down into harmless substances in compost environments. This means that products made from this innovative plastic could be safely composted at home or in industrial facilities, effectively closing the loop on the material's lifecycle.
The team of researchers, led by Geoffrey Coates, a professor of chemistry and chemical biology at Cornell, is optimistic about the potential applications of this technology. The biodegradable plastic could be used to create a wide range of products, including packaging materials, disposable cutlery, and even medical implants. While further research is needed to scale up production and assess the material's full potential, this development marks a significant step towards a more sustainable future for plastics.
