Peripheral fermentation of organic waste - Insights and data from practice

The fermentation of organic waste is a valuable source for alternative energy and nutrients in form of fertiliser. To increase the treatment of organic waste quantities, peripheral digestion plants can have a significant contribution. Although small scale digestion units have higher Investment costs based on the waste quantities processed, a specialisation on suitable wastes and an efficient use of alternative energy and fertiliser can guarantee an economic and ecological success.

Anaerobic degradation is a very cost-effective method for treating organic wastes because the formed biogas can be used for heat and electricity production and the digestatecan be recycled to agriculture as a secondary fertilizer. Various process types areapplied and state of the art which differ in material, reaction conditions and in the form of the used reactor systems. The introduction of anaerobic digestion has shown that organic wastes are a valuable source for energy and nutrients. Anaerobic waste treatmentis done today in biogas plants on middle farm scale as well as on large industrialscale with the best bene.cial and economic outcome. Through the development of newanaerobic treatment technologies based on small scale the recycling rate of organic waste should be increased.
