Large scale anaerobic digestion of both industrial and municipal biodegradable waste with production of high grade bio-methane for the transport sector.
At the Åby Biogas plant, biodegradable waste from several industrial sources as well as from municipal sources is pretreated and pasteurized before it is digested. In the process of digestion, biogas is extracted and then upgraded to high grade bio-methane which is sold to the transport sector as vehicle fuel.
The secondary and output from the process is bio-fertilizer which is used to replace artificial fertilizer in the agricultural sector. Bio-fertilizer is a valuable resource as it recirculates nutrients including some of the finite resources such as phosphorous which is becoming an increasingly dare commodity.
The latest addition to the site is a liquid biogas plant, which enables the use of biogas in industrial processes as well as vehicle fuels at sites with no biogas production.
