The plant was planned and set up by the German manufacturer in collaboration with its French partner Weltec France.
Some 200 standard mÂ³/h of biomethane are generated from production waste and sludge from the company’s own wastewater treatment plant. This approximately corresponds to the gas consumption of a town with a population of 5,000.
“Via the Altho subsidiary Sober, which operates the biogas plant, we actively participate in recycling, producing a green energy source from waste. Additionally, we contribute to the reduction of greenhouse emissions and the energy dependence of the region,” said Christophe ChrÃ©tien, Managing Director of the Sober biogas plant.
First, the solid and liquid substrates are mashed and shredded in the sturdy MULTIMix input system. After this pre-processing, the mixture is fed into the stainless-steel digester, which has a capacity of 4,436 mÂ³.
A post-digester with the same capacity is the last step in the material cycle. Subsequently, the digestate is sold to local farmers, who use it as high-quality fertilizer.
