Pig excrement supply electricity and gas to Brazilian town

A thermoelectric power plant fed by pig excrement is providing electricity to 62 of the 71 public buildings of Entre Rios do Oeste, a town in southern state of Paraná. Pig excrement had become an environmental threat, but the installation in 2006 of a biodigester, an airtight container where waste is deposited, has transformed the liability into an asset. The local council, home to 4,600 people and 250,000 animals, has also started buying the biogas produced by 18 pig farms.
