Adding enzymes to bioplastics can make them disappear

via Popular Science

With so many different plastics entering the waterways that take hundreds of years to decompose, plastic pollution and microplastics are almost everywhere on the planet, from the air to the sea, in vast quantities. Compostable plastics, like corn-based plastic cups and straws, are sometimes touted as a viable solution, but without the infrastructure to properly turn them into compost, they can end up in a landfill

To keep our oceans from becoming even more plastic-filled, scientists are finding the keys to making plastics quickly decompose, and baking them into the plastic’s formula. Ting Xu, professor of materials science and engineering and chemistry at the University of California Berkeley, and her research group investigate biologically available solutions that will allow single-use plastic to biodegrade under easily attainable conditions. In a new study, they describe how they used an innovative polymer coating on enzymes that can be built-in to bioplastics to make them easier to compost at home.
