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...
