GEOLOGICAL BIO
Drywall, also known as plasterboard, is an interior wall or ceiling panel consisting of two paper boards sandwiching a powdery white mineral called gypsum. While drywall appears light and clean, gypsum is extraction-heavy and extremely dusty as a mined rock. In its powdery state, the water-soluble soft sulfate can also be used to amend soils. In this sense, rock is reabsorbed by the earth.
It takes 1 day to install drywall; it takes 299 million years to form gypsum. If undamaged by water, mold, or termites, drywall lasts 30 to 70 years.
EXTRACTION / MANUFACTURING PROCESS
Crush gypsum ︎︎︎ heat or calcine crushed gypsum to dehydrate feedstock ︎︎︎ mix with water and additives to form slurry ︎︎︎ feed between layers of recycled paper on long board machine ︎︎︎ (calcium sulfate recrystallizes/rehydrates and becomes chemically and mechanically bonded to core) ︎︎︎ cut board to length ︎︎︎ dry to remove moisture ︎︎︎ package ︎︎︎ pack and ship
