Gypsum is a natural occurring common mineral found and mined in many countries around the world. Gypsum is used in the manufacture of a wide range of products from plaster, wall board (drywall), and cement, to additives in tofu, baked goods and hand cream.
Drywall should not be landfilled as when it gets wet in an environment that lacks oxygen it gives off hydrogen sulfide gas, awful smelling harmful gas that irritates the eyes, nose and throat and can cause nausea, fatigue, shortness of breath, and chest pain.
Gypsum in building products such as drywall is not only 100% recyclable, it can be recycled over and over. Utilizing recovered gypsum in the lower mainland reduces the environmental impact of building material production because it displaces raw gypsum that is mined in Mexico, transported to the pacific-northwest by freighter and distributed by barge and tug.
Products that incorporate recovered gypsum qualify for LEED (Leadership in Energy and Environmental Design) credits.
