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...

Novel Chain Extenders for Recycling Polyesters

­Executive Summary Polyesters comprise a significant portion of plastics entering landfills. One issue that limits their recycling is natural degradation during melt processing which lowers their molecular weight and melt viscosity. Reactive chain extenders are often used to build back the molecular weight of the polyester, however, their use can...

Repulpable Omniphobic Paper Packaging Solution

Executive SummaryTraditional grease- and water-resistant paper packaging solutions have significant environmental concerns. Water-resistant products using low-density polyethylene (LDPE) liners are not repulpable, increasing municipal waste footprint. Oil-resistance is often achieved using toxic per and polyfluoroalkyl substances, which have been associated...
