Water Dispersible Poly(dimethylsiloxane) Coatings for PFAS Replacement
Executive Summary Polyethylene-, polyvinylidene chloride-, and per- and polyfluoroalkyl substances (PFAS) -coated paper is used in applications requiring barrier properties such as grease and water resistance. However, the use of these chemicals present environmental challenges and make the coated paper difficult to recycle or compost. Researchers...

Biobased Films with Improved Oxygen Barrier
Executive Summary Biobased materials such as polybutylene adipate terephthalate (PBAT), polyglycolic acid (PGA) and polybutylene succinate (PBS) are attractive materials for packaging films due to their positive sustainability aspects including biodegradability. However, their oxygen barrier properties limit the use of these materials to certain applications....

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 Chemical Recycling of Multilayer & Metallized Plastic Packaging Films
Executive Summary In order to combat the growth of global plastic waste, pyrolysis processes have been developed to turn this waste material into gases, oils and waxes. However, these processes usually require high operating temperatures, expensive catalysts and restrictions on the type of plastics they can handle. Researchers at Michigan State University...

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...

100% Recyclable, Fluorine- and Plastic-Free Fat, Grease and Water Resistant Paper Coating
Executive SummaryWith a societal push to remove plastics from the food industry, there is a need for alternative packaging solutions. Governments and corporations alike have begun banning various single-use plastic products in favor of protecting the environment. This technology seeks to improve polymer coating materials for paper products. This technology...

Advanced Intelligent Packaging to Prevent Misuse and Abuse of Prescription Drugs
Executive SummaryThe opioid epidemic in the United States has soared to new heights within the past ten years. In 2016, 215 million opioid prescriptions were handed out at pharmacies across the U.S. resulting in 64 thousands deaths due to overdose or misuse. The opioid crisis has a $193 billion annual impact on the economy with an overdose rate of 245.8...
