Wallboard has served as a light and sturdy method of separating rooms with a limited amount of material. Traditional wallboard has been made out of gypsum, a mineral compound made from the sulfate of lime. The early stages of gypsum’s production require the mining minerals and high firing temperatures. These processes consume a large amount of energy and therefore do not qualify virgin gypsum as a sustainable building material.
