  • biogas reactors for this purpose, it is necessary to treat the organic kitchen waste so that they are storable and transportable.
  • Organic kitchen waste can roughly be divided into two different categories, namely food waste and set-aside waste. The division results both from the place of origin and from the character of the respective organic kitchen waste.
  • Food waste is understood as the remains of already prepared food. Food waste, for example, in the return of plates and trays by the respective guests, employees or patients, before these plates or trays are rinsed. For example, in hospitals, food waste is typically incurred per patient and meal in an amount of about 250 g. Large quantities of catering waste are also produced in restaurants, hotels and canteens.

From these storage tanks, the then largely homogenized biomass is transported by means of a transport vehicle to a biogas plant, in which the biomass is fermented, wherein the fermentation resulting in fumigation gases, especially methane gas, is used to generate electrical energy and / or heat energy. In this way, organic kitchen waste can be recycled and recovered from this environmentally friendly renewable energy.
