Sutco Recycling Technik GmbH has developed a new digestion technology BioPV (organic waste press water digestion) as an alternative digestion process which significantly improves the energy balance and the processing capacity of composting plants.
Sutco Recycling Technik GmbH succeeded in achieving a maximum gas yield from the liquid phase pressed out organic waste with lowest technical efforts during the development of their new digestion process BioPV (organic waste press water digestion). With this technology organic ingredients from the biowaste as a liquid phase are digested and pressed out in biofilm reactors for generating biogas.
Up to now, mainly dry digestion plants have be used for the energetic use of the organic substances contained in organic waste. However, these processes achieve a high biogas yield but require considerable efforts and expenses for the treatment of the digestion rest to provide a quality-based and marketable compost. The conditioning and drying of the digestion rest requires a high energy consumption for that.
Contrary to that, Sutco could largely avoid digestion rests to be disposed of externally with their BioPV. Here, digestion is performed in parallel to the composting process with the liquid phase separated from fresh organic waste. The digestion rest is run in a cycle and is only disposed of in case of excess water in the total plant.
