By editing the polymers of discarded plastics, chemists at the Department of Energy’s Oak Ridge National Laboratory have found a way to generate new macromolecules with more valuable properties than those of the starting material.
By editing the polymers of discarded plastics, chemists at the Department of Energy’s Oak Ridge National Laboratory have found a way to generate new macromolecules with more valuable properties than those of the starting material. Upcycling may help remedy the roughly 450 million tons of plastic discarded worldwide annually, of which only 9% gets recycled; the rest is incinerated or winds up in landfills, oceans or elsewhere.
ORNL’s invention may change plastic’s environmental fate by rearranging polymeric building blocks to customize the properties of plastics. Molecular subunits link to produce polymer chains that can connect through their backbones and cross-linked molecules to form multipurpose plastics. The makeup of polymer chains determines how strong, rigid or heat-resistant those plastics will be.
