Destructing Organic Compounds in Liquids

VALUE PROPOSITION Per and Poly Fluoroalkyl Substances (PFAS) are a group of human-derived chemicals widely used in consumer products and industry applications that can be toxic. PFAS are difficult to deconstruct and current ways for PFAS destruction present many limitations. These limitations include the systems being ineffective at removing short...

Heavy Metal Sensing

VALUE PROPOSITION Heavy metal pollution in soils is widespread in the world, resulting from both natural sources and human activities (e.g., mining and smelting, industrial emission, fossil fuel combustion, etc.). Due to their toxicity, bioaccumulation, and environmental persistence, elevated levels of heavy metals in the environment pose major threats...

Biodegradable Barrier Coating for Paper

Executive Summary Coated paper is used in a variety of packaging applications including fresh produce, cheeses, confectionary, frozen fish and fast food. To achieve sufficient barrier properties, the paper is often coated with petroleum based waxes or polyfluorinated substances (PFAS). However, these coatings are not environmentally attractive and...

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...

Recombinant Protein for Rare Earth Element Binding

Executive Summary Rare earth elements (REEs) are essential materials used in advanced technologies such as electronics, process catalysts, magnets, batteries and MRI contrast agents. Although used in small quantities for each application, they end up in surface water and soil during mining, processing and waste disposal. This presents growing environmental...
