Process for Depolymerizing Recycled Polystyrenes

­Executive Summary Each year, billions of lbs of polystyrene and styrene copolymers are discarded as waste and very little is recycled. While some technologies have attempted pyrolysis in fluidized bed reactors or solvent processes to convert the polystyrene back to monomer, high costs, long process times and a myriad of reaction products have...

Rapid Process for Depolymerizing Recycled PET

­Executive Summary Each year, billions of lbs of polyethylene terephthalate (PET) and polyethylene terephthalate glycol (PETG) are discarded as waste. While some of the material is separated, recycled and incorporated into new materials, the degradation of the polymers back to their original monomers (a.k.a. chemical recycling) remains prohibitive...
