Versatile input material is important<br />
In most German bio-methane plants energy crops are used, such as maize,<br />
beetroot and grass. There have been controversial discussions about these<br />
contributing to monoculture and a rise of rent for fields. For Germany and Europe<br />
this cannot be confirmed: Only in a few areas e.g. maize is grown more than 50<br />
percent and this is due to fodder production. A rise of rent could also be seen only<br />
in a small number of regions. Here, reasons are rather loss of land due to street<br />
construction, industrial areas, water protection and an increasing demand of land<br />
for livestock husbandry.<br />
Concerning bioenergy production, constant increases of harvesting efficiency and<br />
the use of fallow land are leading to better agricultural efficiency and to a decrease<br />
of conflict potential. Additionally, bio-methane plant owners put a lot of effort into<br />
using waste material from fodder production such as manure, as well as household<br />
waste. Feeding bio-methane plants with so far unused material is expected to<br />
increase further in the future.<br />
