The input is made up of almost 7 000 t of substrates, of which 2 500 t are liquid cattle manure. The greenhouse gas emissions generated in the process of providing the substrates (cultivation, fertilization and transport) add up to 200 t. Further emissions are generated during plant construction and while operating it, so that a total of 455 t of CO2 are generated p.a.
If the same quantity of power and heat was provided by fossil energy carriers, 1 100 t of CO2 would be generated. The utilization of biogas thus results in net savings of 650 t of CO2 per year. Even higher savings can be achieved, when using more liquid manure, residues and waste as input materials. Extending the utilization of heat (up to 100 households would be possible) improves the balance further, so that savings of almost 100% are possible. Apart from the carbon footprint, the energy balance of a biogas plant is also clearly positive: up to five times more energy is generated than consumed
