Pre-conference 9 mars Stockholm-Västerås

Tuesday 9 March

Pre-conference tour Stockholm-Örebro with stop for study-visit in Västerås

At 7 o´clock

am heading for the unique biogas project and waste handling at Svensk Växtkraft AB in Västeras.

Svensk Växtkraft AB in Västeras is a biogas plant taking the technology one step further. It uses sorted household and catering waste, grease trap removal waste, and ley crops from 300 hectares as raw materials for the digester. The gas is upgraded to vehicle fuel, and used locally both for heavy and light-duty vehicles, as well as exported to other cities.

The plant produces 23 GWh of biogas per year. In addition, 3 500 tons solid and 13 000 tons liquid bio-manure is produced. The plant is owned by the local energy and waste handling utilities, by the Farmer's union, and by 17 local farmers.

The plant is located at the waste treatment facility Gryta north of the city, run by VafabMiljö AB. This company is owned by several municipalities and deals with sustainable and environmentally sound handling of waste from house-holds and businesses. 14 000 tons of the organic waste per year is used as substrate in the biogas plant in Västeras. The source-separation of organic waste is voluntary in Västeras and yet 90% of the house-hold participate in the separation scheme.

Coffee in Västerås. After our visit in Västerås we´ll move on to Örebro.

At noon
