Scientists at Rice University have developed a technique to turn pyrolyzed plastic ash, a product of plastic recycling, into graphene. The technique produces turbostratic graphene flakes that can be directly added to other substances, such as films of polyvinyl alcohol, that better resist water in packaging. Last October, the same scientists reported on a process to convert waste plastic into graphene. This time, the new process turns plastic that is not recovered by recycling into a useful product.
