A new type of catalyst breaks down polyolefin plastics into new, useful products. This project is part of a new strategy to reduce the amount of plastic waste and its impact on our environment, as well as recover value that is lost when plastics are thrown away. The catalyst was developed by a team from the Institute for Cooperative Upcycling of Plastic (iCOUP), a U.S. Department of Energy, Energy Frontier Research Center.
Researchers created a new catalyst that transforms hydrocarbons into chemicals and materials that are higher value, easier to recycle, and biodegrade in the environment. This catalyst transforms materials such as motor oil, plastics in single-use grocery bags, water or milk bottles, and their caps, and even natural gas.
