ABSTRACT:
A solvent based plastics recycling process directly reduces large volumes of post consumer plastic waste materials by up to 500% by volume. Minimal sorting and no cleaning is required, and large percentages of contaminants are tolerated. The process yields a highly adhesive resin which cures to a hard wood or masonry type material. The reduced end product, an epoxy sludge, may be formed to provide a lumber or brick substitute. Large percentages of shredded paper and other waste materials, including metals, may be added to the plastic waste materials, if desired.
