Foamed Drywall Waste Panels (FDWP): A fire-protective insulation technology
Unmet Need: Environmentally friendly fire-protective insulation material
Flammable plastic foam insulation (aka Styrofoam) has been under scrutiny in recent building fires. Noncombustible alternatives are costly & produced with carbon-emitting fuels. Concurrently, there is pressure to end landfilling of gypsum drywall waste from building construction...

Masonry Blocks using Recycled Gypsum Wallboard
Unmet Need: New use for construction & demolition gypsum drywall
Construction of an average 2000 square foot home produces more than a ton of gypsum wallboard waste. Gypsum wallboard waste is a low-value material, typically disposed of in landfills. Landfill disposal presents a significant problem due to anaerobic soil bacteria consuming gypsum...

Biobased Epoxy Resins and Curing Agents using Rosin Acids as Building Blocks
Abstract WSU inventors have developed epoxy resin systems and carboxylic terminated polyesters using rosin acids as building blocks. This provides a method to make epoxy resin systems that do not contain Bisphenol A (BPA). Current powder coating polyester resins are built largely on tere-or isophthalic acid and trimellitic anhydride as rigid monomers...
