Biogas from Energy Crop Digestion
Currently biogas plays a smaller, but steadily growing role. Traditionally applied for sewage sludge treatmentand stabilisation purposes, energy recovery from biogas was a welcome by-product. However, biogas has become a well established energy resource, especially through the use of renewable biomass i.e. “energy crops”. Since about 1950, biogas production from manure and /or energy crops, continued to develop as an important new farm enterprise.
