Water, Air and More
At National Gypsum, wallboard plant process water is recycled, resulting in zero discharge. Storm water run-off at newer plants is treated in sedimentation ponds prior to discharge. Dust collected in baghouse systems is recycled into the process. The company uses low NOx burners to reduce emissions. Solvents used to wash parts, waste oils, spent vehicle batteries, and scrap metal are sent to third-party recyclers.
