New CleanBoard Drywall is Made From Coal Power Plant Residue

January 16th, 2009 by Ariel Schwartz

Earlier this week, CleanBoard started talking publicly about what it calls “the most environmentally friendly drywall on earth.” That’s quite a claim, but there might be something to it: the drywall will be produced in a solar-powered factory and made from coal-fired power plant residue.

CleanBoard has developed a system that uses mirrors to collect the sun’s rays on a heat collector which heats a transfer fluid. The transfer fluid heats drywall ovens up to 200 degrees Celsius, and leftover fluid is stored in pressurized chambers to make drywall on cloudy days.

The Mojave Desert-based solar thermal plant will be up and running soon, but the company is currently doing limited manufacturing at another site and purchasing carbon offsets to counteract pollution.

And while all drywall uses gypsum, CleanBoard sources its product from coal-fired power plants and unused wall board from construction sites.

The company estimates that it will produce 2 million square feet of drywall in 2010, 10 million square feet in 2011, and 100 million square feet at top volume.
