Methane production through anaerobic digestion of various energy crops grown in sustainable crop rotations.
Biogas production is of major importance for the sustainable use of agrarian biomass as renewable energy source. Economic biogas production depends on high biogas yields.
The project aimed at optimising anaerobic digestion of energy crops. The following aspects were investigated: suitability of different crop species and varieties, optimum time of harvesting, specific methane yield and methane yield per hectare.
The experiments carried out for the EU member states covered 7 maize, 2 winter wheat, 2 triticale varieties, 1 winter rye, and 2 sunflower varieties and 6 variants with permanent grassland.
In the course of the vegetation period, biomass yield and biomass composition were measured. Anaerobic digestion was carried out in eudiometer batch digesters.

Anaerobic Digestion
Biogas and Bio-methane as fuels is growing globally at a rapid pace. Driving forces such as an alarming climate change, an increased dependence on diminishing fossil fuels, and a need to create jobs contributes to the expansion of a new industry.
