In Ingolstadt, a mono-incineration plant is to be built over the heads of the citizens. But the local residents are fighting back and looking for green solutions for sewage sludge utilisation. 

To this end, Mr. Rottenkolber visited us and told us about the planned construction of a mono-incineration plant. Our RSR process could be a good alternative. Since the fertiliser produced from the process can be used again in agriculture in the immediate vicinity. 


Other aspects that speak for the use of our RSR process: 

  • regional supply of fertiliser to farmers, which complies with the Fertiliser Ordinance and can thus be spread on the fields for cultivation purposes
  • with this regional supply, the currently rising fertiliser prices can be counteracted à Independence is promoted, as no imports of fertiliser will be necessary in the future.
  • the phosphorus in the fertiliser can increase farmers' yields and thus guarantee the food security of the citizens.
  • the phosphorus and other valuable substances in the fertiliser such as potassium, nitrogen ... result in a long-term use of the soils à the introduction of the valuable substances prevents soil leaching!
  • phosphorus remains in the fertiliser and is recycled in the sense of the circular economy à phosphorus has been on the list of critical raw materials since 2010 and there is no degradable phosphate deposit in the EU. For this reason, it is important to recover phosphorus from secondary raw materials, such as sewage sludge.
