149 produced gas is upgraded at the plant ong>andong> distributed to refueling stations in Norrkoping by vehicles with swap-body units. Distribution of gas to surrounding cities also takes place. A gas pipe in Norrkoping was constructed in August 2007.

The fertilizers produced at Händelö is KRAV-labeled, ong>andong> therefore certificated for organic farming. KRAV is an organization working with the organic market in Sweden. They are active members of IFOAM – International Federation of Organic Agriculture Movements ong>andong> they promote the KRAVlabel. The fertilizer produced at Åby plant is certificated for conventional farming. The Åby biogas plant is located close to the wastewater treatment plant Nykvarn, which was an important reason for the location since the biogas produced at the Nykvarn plant could be upgraded at the same upgrading plant. Another important advantage with the location was the distance to the substrate, i.e. the slaughter house, which was located nearby as well. Some of the liquefied waste from the slaughter house is actually transmitted to the plant by pipes. (Chemical Engineering ong>andong> Technology department KTH., 2007) The Åby plant (Picture 40.) is located only 1 km from the city of Linköping, which is an advantage when distributing the gas to refueling stations. The location is also close to the waste treatment plant Gärstad, at which the municipal household waste is incinerated ong>andong> all different kinds of waste is treated.
