by AF 1027 d3 — October 29, 2008—In response to the lack of green alternatives to conventional drywall manufacturing, Spertech has introduced Greentech Wallboard. This patented wallboard technology is developed from recycled materials without producing harmful carbon emissions during the manufacturing process, says the company.
“Drywall is the most common indoor building material in the United States, but it’s produced in a manner that’s highly energy-intensive, emitting an excessive amount of greenhouse gasses, said Edwin Brasch, president and chief executive officer at Spertech. “With Greentech Wallboard, Spertech is developing a commercially viable alternative to traditional drywall that’s emissions-free. We’re now in the stage of business development where we’re actively pursuing partners to license this innovative technology.
Greentech Wallboard contains the same strength and density of standard drywall, but utilizes a unique method of development, according to Spertech. Rather than superheating mined gypsum to high temperatures, a manufacturing technique that generates carbon dioxide emissions, Greentech Wallboard is comprised of 98% fly ash, a residue by-product of coal-fired electric plants that would otherwise be deposited in landfills or released into the atmosphere. This ground-breaking material science does not require heating, and therefore leaves virtually no carbon footprint during manufacturing.
Fly ash has been safely used for years in other construction materials, including cement and concrete, and is classified by the Environmental Protection Agency as a non-hazardous waste. According to some estimates, approximately 40,000,000 tons of fly ash are dumped in landfills every year.
