Industrial biogas plants
Industrial plants mainly use residues from their own production and use them to generate energy in the form of heat and/or electricity. This is a win-win situation. Such residues and by-products include, for example, waste from the sugar and potato industry, slaughterhouse waste, but also product waste such as stillage, e.g. from the ethanol industry.
Digestion plants for biowaste and kitchen waste
Biogas plants for biowaste are also industrial biogas plants; they differ primarily in the input material. These are food scraps and kitchen waste, as well as municipal biowaste, often in combination with other input substrates such as sewage sludge. These wastes do not consist exclusively of organic matter and therefore require special process technology.
