ALTERNATIVE FUELS * Norway - City buses turn to sewage for 'clean' fuel
Can the key to "clean" energy be found down in the sewer?
(Photo: A biogas bus being refueled) Oslo,Norway -AFP -22 March 2009: -- That's the idea in Oslo, where city officials soon plan to introduce buses that run on biofuels extracted from human waste... As of 2010, the new buses are due to start plying the streets of the Norwegian capital...
(Photo: A biogas bus)... The biofuel, which is methane generated by fermenting sludge, will come from the Bekkelaget sewage treatment plant which handles waste from 250,000 city dwellers... "By going to the bathroom, a person produces the equivalent of eight litres (2.1 gallons) of diesel per year. That may not seem like a lot, but multiplied by 250,000 people, that is enough to operate 80 buses for 100,000 kilometres (62,000 miles) each," Ole Jakob Johansen, one of the people in charge of the project at Oslo city hall, says...

In addition to being carbon neutral, it emits 78 percent less nitrogen oxide and 98 percent fewer fine particles -- two causes of respiratory illnesses -- and is 92 percent less noisy... Even the price is advantageous, says Johansen...Labels: alternative fuel
