GM Orion Assembly Plant to get 40 percent power from landfill gas
According to the General Motors (NYSE:GM, TSX: GMM) news release, the use of the landfill gas will save GM $1.1 million a year in energy costs. Furthermore, it cuts the amount of greenhouse gases, sulfur dioxide and nitrogen oxides released in the air.
During most of the year, the system run exclusively on landfill gas primarily to generate steam for heating and compressed air.
“Orion is a great example of the latest technologies employed by GM manufacturing around the globe,” said Eric Stevens, GM vice president of Global Manufacturing Engineering. “As we converted the facility to support the small car program, we took every opportunity to engineer in flexibility and lean manufacturing concepts.”
Use of landfill gas is just one of the sustainable methods that lessen the plant’s environmental impact. Others include:
1) Lighting system upgrades that saved more than 5,944 megawatts of electricity per year and $430,000 while also cutting CO2 by 3,676 metric tons. Plant workers track energy use on an hourly basis with sophisticated software, enabling them to see real-time usage by department to improve their equipment shut-down activities.
2) Plant workers reduced total waste by 26 percent from 2005 to 2009.
3) An upgraded paint shop is heated by natural and landfill gas, and uses half of the energy per vehicle of the one it replaced. Both the Sonic and Verano use a new eco paint that eliminates the need for a primer oven and increases quality and appearance due to waterborne base coats.
