Technical requirements on agricultural cofermentation plants chances and problems shown on concrete examples

Agricultural co-fermentation plants are a reasonable option for farmers to produce organic fertilizer and renewable energy (biogas) from substances like liquid manure, bio waste or agricultural waste.

Therefore the transfer rates are often very high. In some cases there are problems because of odour emissions from co-fermentation plants. In this paper a study about several co-fermentation plants in Germany is presented based on a project worked out in 2002. It was the task to examine the sources of odour and to investigate how odour emissions could be avoided in future. Additionally the waste management in these plants had to be examined to optimise the process. Furthermore the advantages and potentials of a biomass-alliance like the “Soltauer Biogas und Rohstoff GmbH & Co. KG” and the 21 participating plants have been documented with regard to the optimised application of organic substances out of food industry production in co-fermentation plants. The results are basis for suggestions for construction, operation and a guideline for low emission cofermentation plants. The further need of investigations is described.
