The process comprises receiving recyclable plastic feedstock including high density polyethylene, low density polyethylene, expanded polyethylene, and stretched wrap, separating the plastic feedstock by plastics of like type, grinding the separated plastics into particulate while maintaining the temperature below said separated plastic's decomposition and melting point. The plastics are mixed in proportion, adding a biodegradable additive to the particulated plastic mixture with further mixing to produce the biodegradable plastic. Optionally, the resulting plastic is extruded for later use. | 04-21-2016 |
