Titolo: A valve in the Bekkelaget treatment plan

Descrizione: A valve in the Bekkelaget treatment plant to monitor the methane in the Biofuel factory is pictured in Oslo on March 14, 2009. The city officials of Oslo plan to introduce as of 2010 buses that run on biofuels. Biofuels, extracted from wastewater is a ''clean'' energy, which is methane generated by fermenting sludge, and will come from the Bekkelaget sewage treatment plant which handles waste from 250,000 city dwellers. Biomethane has the added advantage of not impacting food supplies, nor does it require fertilisation or deplete precious water resources. The initiative, if extended to Oslo's second waste treatment plant and complemented with biofuels made from food waste, could provide enough fuel for all of Oslo's 350 to 400 buses.
