Energy Conservation Efforts
Well-Oiled Machines That Run On Natural Gas
All of our American Gypsum plants operate on natural gas to produce our products. We collect data and continuously monitor all natural gas fired equipment for complete oversight and management of our energy consumption on a daily basis. We also perform energy audits at every facility each year.
At our Georgetown, South Carolina facility, the audits we've performed have helped us develop that location into a financially and environmentally positive facility. This plant takes synthetic material that has a very high free moisture content and converts it into wallboard with better energy efficiency than most of our other plants that process natural gypsum, which has little or no free moisture.
How Does The Georgetown Facility Create Better Energy Efficiency?
- We use high efficiency burners.
- Heat exchangers are used on dryer exhaust stack to preheat combustion air to burners.
- We capture exhaust gases from hotter dryer zones and circulate it back into the dryer into lower temperature zones to utilize all heat possible.
- Exhaust stream from the cooling down our gypsum stucco is reused to provide preheated combustion air for the FGD drying process.
