As part of a Joint Venture, the technology group The Linde Group (Munich, Germany; www.linde.com) and Waste Management Inc. (Houston, Tex.; www.wm.com) will build the world’s biggest plant for the conversion of landfill gas into environmentally friendly biogas in Livermore, California. The plant will begin operating in 2009. It is intended that the liquefied biogas will be used as a fuel for Waste Management’s 300 trash and recycling collection vehicles in California. The capital expenditure amounts to $15 million.
Linde is responsible for the engineering of the plant as well as the cleaning and subsequent liquefaction of the landfill gas. Waste Management, North America’s leading recycling and waste management company, is supplying the landfill gas, which comes from the natural decomposition of organic waste. It is expected that the plant will produce around 50,000 L/d of liquid biogas.
