Abstract

Apparatus, systems (including solvent or enzyme), and methods of degrading plastic are described. Plastic waste is stretched in the presence of solvent. The surface may be further treated to increase hydrophilicity. The resulting plastics can be treated with plastic-degrading enzyme either with microorganisms or direct application of enzyme.
