Biochar in the biogas plant
Biochar also has a number of advantages for the biogas process when it comes to climate protection. If plant coal is added to the fermentation residue, nutrient losses and climate-damaging methane gas losses are reduced. If the fermentation residue is carbonised, high-quality biochar can be produced from it and the carbon contained in the fermentation residue is bound over the long term. This not only protects the environment, but also ensures substantially improved efficiency of the gas production process.

Already today, almost 70 % of renewable energies in Germany are generated from biomass. However, at around 300 g CO2 / kWh, electricity from biogas from conventional corn monocultures is only slightly better than the conversion of fossil…
Various international studies prove an increased gas yield through the addition of biochar to the biogas process. With approx. 9,200 biogas plants (Statista 2018), Germany in particular offers great potential for optimisation. The study investigates which…
