The individual planning concept was drawn up in 2007, taking into account the special features on site and using existing tanks and aggregates. The technical implementation was carried out by the plant operator himself. The large-scale functionality of the process was demonstrated in practical operation at the fermentation residue treatment plant, which operates in fully automatic mode. Since 2011, long-term experience with the use of a lot of poultry manure with recycling of the N-reduced fermentation residues. 2016 Testing of the FaserPlus process for co-treatment of biogas fibers (separation after stripping).

After removal of the ammonium nitrogen, 70% of the liquid fermentation residues are returned to the biogas plant. The high proportion of nitrogen that enters the biogas plant with the poultry manure can thus be almost completely removed from the process and converted to mineral fertilizers. By recovering heat from the digestate treatment, the neighboring chicken fattening farm can also be supplied with heat.
