Popular Science’s “Best of What’s New” Award in green tech innovation for their eco-friendly drywall called EcoRock. EcoRock requires 80 percent less energy to produce and cuts CO2 output by 90 percent in comparison to traditional gypsum-based drywall. These reductions in energy and CO2 are won by getting rid of 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 itself fully recyclable.

Gypsum drywall factories produce about 20 billion pounds of greenhouse gases a year.
