How does CleanBoard green your home? It uses carbon-neutral drywall made of recycled materials using solar thermal technology.

San Francisco-based CleanBoard’s CEO and founder Rod MacGregor plans on opening a plant this year in California’s Mojave Desert and using solar heat for industrial processes (SHIP), which collects energy close to the way solar thermal electric power is collected, but uses the produced heat in the industrial process. Currently, the drywall is being manufactured in China.

Drywall can be a wasteful segment of building materials because it’s cut to fit at the building site – there’s a lot of discarded scraps of drywall piling up and MacGregor’s company can contract with these builders to haul the scrapped drywall away and recycle it into new drywall.

CleanBoard obtains more than 80 percent of the supplies from coal-fired power plants. The scrubbers used in those power plants remove sulfur from emissions, which generates calcium sulfate – the basis for gypsum. Power plants in the U.S. are required to scrub emissions; however, China is not. CleanBoard can offer a financial incentive to plants in China to install scrubbers.

His goal is to reduce harmful emissions, prevent scrap drywall waste, produce drywall without open-pit mining for materials, and use solar thermal energy instead of electricity.

EcoRock – The Other Green Drywall

EcoRock, made by Serious Materials, is drywall made from 80% recycled material but no gypsum, making it 5 times more environmentally friendly than gypsum. It also uses 80% less energy to produce than gypsum drywall because it’s naturally cured and dried. And, it is the most mold-resistant and lowest emitting drywall.
