The paint shop is part of the BMW Manufacturing plant in Spartanbug, South Carolina. The facility has been running partly on methane gas since 2002. There is a nine-and-a-half-mile pipeline from the landfill to the facility that will now provide half of the plant's energy needs. The change means the plant will reduce local carbon dioxide emissions by approximately 17,000 tons a year. The renewable gas also saves BMW about a million dollars a year, according to the article.
