• Manure and dung are  fed into the biogas plant.

  • In the fermenter, heated to approx. 38-40 °C, the substrate is decomposed by the

    micro organisms under exclusion of light and oxygen. The final product of this fermentation process is biogas with methane as the main ingredient. But aggressive hydrogen sulphide is also contained in the biogas. A fermenter made of stainless steel has the clear advantage that it withstands the attacks of the hydrogen sulphide and is usable for decades. Furthermore, a stainless steel fermenter provides the opportunity to operation the biogas plant also in the thermophile temperature range (up to 56 °C).

  • Once the substrate has been fermented, it is transported to the fermentation residues end storage tank and can be retrieved from there for further utilisation.

  • The biogas generated is stored in the gas holder and from there it

  • is burned in the combined heat and power plant  to generate electricity and heat.
