Oslo introduces buses powered by a by-product of food waste

5th March 2014

On 12th February 2014 a biogas liquefaction plant located in Nes, Romerike, an agricultural region close to Oslo, was officially opened, putting the region at the forefront of environmental innovation. The plant, operated by Cambi AS on behalf of EGE (Waste-to-Energy Agency) and the City of Oslo, will produce biomethane from household food waste which will provide biofuel for buses in Oslo.

By converting household food waste into liquid biomethane, this new liquefaction plant will produce enough fuel to power 135 buses. Consequently, carbon dioxide (CO2) emissions will be reduced by approximately 10,000 tons a year. Particle emissions will also be considerably lower and noise levels will be reduced.

This plant will mean that 135 Oslo region buses will be able to run on biogas. As a result, CO2 emissions will be reduced by some 10,000 tons a year and particle emissions will also be significantly lowered. The air will be cleaner and noise levels will be reduced, and these are benefits that everyone in the region will enjoy,” noted Jannicke Gerner Bjerkås, Director Communications and CSR, Waste-to-Energy Agency, City of Oslo.

When fully operable the biogas liquefaction plant will treat over 50,000 tons of food waste a year, equating to around 14,000 Nm3 (normal cubic meters) of biomethane per day.

European Green Capital Award

The EU has committed to raising the share of EU energy consumption produced from renewable resources to 20% by 2020. ‘Climate change: mitigation and adaptation’ is one of the 12 environmental indicators assessed by the European Green Capital Expert Evaluation Panel when assessing cities that are applying for the European Green Capital Award. The City of Oslo was shortlisted for the Award in 2010/2011 and is one of twelve cities that have applied for the 2016 Award.
