Summary

The relevance of biogas on organic farms is increasing. To analyse the structures, development and importance of biogas production in the organic sector, telephone-based and face-to-face interviews have been carried out on more than 80 plant managers. Today at least 120 biogas plants with an electrical power of 15-20 MWel are installed. Since 2005 the number of biogas plants has increased by about 1/3, the electrical power by about 64%. Most of the plants are located on forage cropping farms, but at currently more and more so-called biogas farms have come into existence. The main reasons for acquiring biogas – beside generation income from electricity sales - are positive effects on crop production, upgrading of organic fertilis-ers and a sensible use of grass/clover and grassland. The acquisition of substrates and the use of maize have a great importance in organic farming.
