NREL researchers find way to upcycle plastics into higher value greener products

In Colorado, researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have discovered a method of plastics upcycling—transforming discarded products into new, high-value materials of better quality and environmental value—that could economically incentivize the recycling of waste plastics and help solve one of the world’s most looming pollution problems.

Published in Joule, “Combining reclaimed PET with bio-based monomers enables plastics upcycling,” describes how the NREL team chemically combined reclaimed polyethylene terephthalate (PET) plastic, in the form of single-use beverage bottles, with bio-based compounds to produce higher-value fiber-reinforced plastics (FRPs) that can be used in products from snowboards to vehicle parts to wind turbines. Not only are the resulting composites worth more than double the original PET, the FRPs exhibit twice the strength and improved adhesion to fiberglass when compared to the standard petroleum-derived FRP.
