Innovative sewage sludge recycling Text automatically translated in your browsing language Automatically translated
The aim of the research project is to develop a new innovative process for the disposal of municipal sewage sludge within the meaning of Section 3(1) of the Wastewater Treatment Ordinance. A special focus is to be placed on the development of a process for phosphorus recovery, which will be required by law from 2032. The recovered phosphorus should be able to be used as a substitute fertilizer. At the same time, the recycling of the sewage sludge is to be optimised in such a way that it can be CO2-neutral: This can be done by using the energy contained in the sewage sludge as a substitute fuel or by storing it as an energy resource. It must be investigated whether and how this results in municipal added value in the recycling of sewage sludge, which can at least partially offset the costs for the disposal of sewage sludge. The existing state-of-the-art mono-incineration or co-incineration plants are not yet suitable for this purpose from the point of view of the wastewater plant, as the combustion heat is partly used for energy purposes, but this does not create any municipal added value and more or less long transport routes for the sewage sludge are also required. During the negotiation phase, the contracting authority and the contractor must agree on annual research and development stages as well as intermediate objectives that are measurable/verifiable and become part of the contract within the framework of the payment terms.
