Biogas
Biogas can be produced by fermenting fruit and vegetable residues, sewage sludge and manure. Biogas is an important asset in making our energy supply more sustainable. Biogas that is generated energy-neutrally can be used in combined heat and power plants or upgraded to green gas that is mixed into the natural gas network. Kiwa's biogas experts monitor the quality of this gas and advise on its production and use.
