Smith's Creek, Michigan - Material collected from septic tanks is injected through green pipes into St. Clair County's Smith's Creek Landfill. The system speeds the decay of organic waste in the landfill, accelerating the recovery of methane gas which is used by DTE Biomass Energy to generate enough electricity to power about 3,000 homes.
