The residue produced at Händelö, as well as Åby, is used as fertilizer in the
agriculture. The fertilizers produced at Händelö is KRAV-labeled, <strong>and</strong> 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 <strong>and</strong> 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 <strong>and</strong> 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 <strong>and</strong> all different kinds of waste is
treated.
