Food waste to fuel Oslo's City buses
Petrolplaza.com, March 26th
Stale bread, banana peels, coffee grounds and other food waste will be transformed into green fuel for Oslo's city buses starting next year. The Norwegian capital's new biogas plant will supply the fuel and also provide nutrient-rich bio-fertilizer for agriculture
The plant will be able to process 50,000 tonnes of food waste annually, converting it to environment-friendly fuel for 135 municipal buses as well as enough bio-fertilizer for roughly 100 medium-sized local farms. Biogas is a carbon dioxide-neutral fuel produced from biomass such as food waste, sewage sludge and manure.
Currently, 65 Oslo buses are powered by biogas produced from sludge from the city's sewage treatment plant. When the new biogas plant reaches its full capacity in 2013, the local bus company will have enough biogas for at least 200 buses.
- Running on biogas will reduce emissions from public transport, which means less airborne particulate matter and thus improved air quality in Oslo. What's more, the biogas buses run quietly, explains acting plant manager Anna-Karin Eriksson of the Oslo Municipality Waste-to-Energy Agency.
Biogas in buses means cleaner air and less noise for Oslo's 500,000 residents. Biogas not only helps to improve air quality, it is meant to be good business as well.
The new plant is slated to produce the energy equivalent of four million liters of diesel fuel annually. The plant is being constructed by the Norwegian company Cambi AS, which won the contract after intense competition with foreign companies.
