Major investment in biogas and public transport in Örebro


Detailed description of the Good Practice

On 1 October 2009 the Municipality of Örebro put into action, in conjunction with other public sector organisations, local trade and industry, and local farmers, several parts of a widespread scheme to increase the production and use of biogas (methane). On the same day, new buses using biogas began to appear on the streets of the town. A new and expanded bus route network will be introduced in April next year.

More Details of the Good Practice

The Municipality of Örebro has been delivering biogas to local food companies for many years. This biogas came from the anaerobic digestion of slurry at the sewage treatment plant and from collecting gas that would otherwise have leaked out of waste depots. Since 2007 there has also been a plant that upgrades the biogas to vehicle fuel.
Starting in October 2009, local biogas production was quadrupled. A private company started up a new production plant which is the biggest in Sweden. This plant chiefly uses energy crops from agriculture, but manure, substandard crops, bi-products from the food manufacturing industry and wetland grass are also used. The farming industry has shown great interest in cultivating biogas crops as a part of crop rotation planning.
Around half of the volume produced is delivered to a newly-built bus depot, where the municipality’s new biogas buses are refuelled. The rest is delivered to the two biogas filling stations in Örebro and to Stockholm, to support the growing biogas market there.
The total production capability of vehicle gas is 60 GWh from the new biogas production plant and 20 GWh from the sewage treatment plant when both are operating at full capacity. This is the equivalent of over 8 million cubic metres of vehicle gas, which is used instead of roughly the same amount of fossil fuel.
Emissions of carbon dioxide are thereby being reduced by approximately 20,000 tons per year. Just changing from diesel to biogas in the city’s bus traffic will reduce emissions by 3,000 tons per year. The residue from the anaerobic digestion process is returned to the farmers to be used as fertiliser.
The diesel-powered city buses in Örebro were replaced with 61 new biogas-driven buses on 1 October. In addition to the overall climate benefits, the air quality in the city has improved since biogas replaced diesel. Within the next few years regional buses will also be powered by biogas.
In April 2010 a new bus route network will come into force for the city buses, which will dramatically improve the level of service and increase the possibility for people to leave the car behind and travel on public transport instead.
