The production of renewable gas in Europe (EU-27) was 14.3 Mtoe in 20132, which corresponds with
approximately 11 billion m3 methane or 3% of the total natural gas consumption. Almost all renewable gas was
biogas, produced from landfill or by anaerobic digestion of sludge, manure, crops, industrial and domestic wastes
and crop residues. In Europe, Germany was by far the largest producer of biogas (50%) followed by the United
Kingdom and Italy, both with a share of 14% in 2013. In Germany and Italy decentralized (mainly agricultural)
biogas plants were the main source with a share of over 70% while in UK the share of landfill capture was over
70%2. The most important substrates in anaerobic digestion were manure and energy crops, intentially grown for
this purpose. The share of wastes and crop residues was small while future increase of biogas production is expected
to be mainly based on energy crops
