Kitchen Waste Dry Fermentation
Organic waste coming from restaurants (food waste) can be used to produce biogas, through the “anaerobic digestion” process.
The anaerobic digestion is a biological process that allows to transform part of the biogenic carbon contained in the waste into a gas rich in methane (biogas).The biogas can be easily used as fuel for energy production. Until now, biogas production was mainly concentrated on systems based on “wet anaerobic digestion” process. The wet anaerobic digestion plants present considerable operational issues as waste must be pretreated and mixed with a liquid to make it pumpable.
The "dry fermentation" process allows the treatment of biomass, such as food waste, organic fraction of municipal solid waste, cuttings of green or otherwise, without the need to mix the material with a liquid, to make it pumpable fluid, as required by the “wet fermentation” process. With this process you can treat any type of biomass with high dry matter content (up to 50%).
