FOLSOM, Calif.--(BUSINESS WIRE)--Oct. 12, 2009-- Waste Connections, Inc. today announced that it has entered into a long-term agreement to expand its landfill gas to energy operations at the Potrero Hills Landfill in Northern California. Under the 25-year agreement with DTE Biomass Energy, landfill gas will be recovered and converted into renewable electric power. The project is expected to produce enough electricity to power approximately 7,000 homes per year.
