Serious Materials has won Popular Science's "Best of What's New" Award in green tech innovation for their eco-friendly drywall called EcoRock.
What makes this drywall so special? EcoRock requires 80 percent less energy to produce and cuts CO2 output by 90 percent compared to traditional gypsum-based drywall. These reductions in energy and CO2 are accomplished by eliminating heaters, dryers, calcining and burning of fossil fuels. The material congeals without heat and no mining is necessary in its production. It uses 85 percent recycled content and is fully recyclable. The company claims it holds up even better than gypsum drywall.
In contrast, traditional drywall is made by mining and then roasting gypsum rock in 500 degree kilns. Drywall factories produce about 20 billion pounds of greenhouse gases a year.
EcoRock is just one of the company's many green building products like ThermaProof insulated windows and sustainable sound-proof doors. EcoRock costs $14 - $20 per 4x8-foot sheet, about the same as high-end drywall and will be available starting in 2009.
