DTE Gas, a subsidiary of DTE Energy, is providing pipeline-quality natural gas, which was converted from landfill gas, to its residential customers. DTE Gas' BioGreenGas program contributes to the development of that pipeline-quality natural gas at the Sauk Trail Hills landfill in Canton, Mich. Clean Energy Renewable Fuels (CERF), a division of Clean Energy Fuels, develops U.S. production facilities that generate and sell renewable natural gas. CERF created a plant to purify the biogas at Sauk Trail Hills landfill. DTE Pipeline Company invested approximately $2 million to build a pipeline and a meter station at Sauk Trail Hills.
