The Kompetenzzentrum Wasser Berlin (KWB - Berlin Centre of Competence for Water) heads new EU-funded demonstration project fostering phosphorus recycling from wastewater.  In close cooperation with partners from science, industry sectors and agricultural professionals, the best practice recycling methods will be evaluated. Besides different technical solutions, these methods explicitly include also the direct use of wastewater in agriculture. The project aims to increase the recycling rate of phosphorus from wastewater to 80 %. In addition to the evaluation of the phosphorus yield, systematic investigations will also be carried out on the fertilising effect of the recycling products. Furthermore, the market potential of the individual recycling schemes and recycling products will be analysed.

The targeted recycling of phosphorus from wastewater could cover up to 60% of the demand in Germany. Numerous methods have been developed in the frame of pilot projects, but none of them has allowed for a large scale implementation. According to Andreas Hartmann, Managing Director of Kompetenzzentrum Wasser Berlin, this is due to the fact that the research activities carried out so far have rather focused on phosphorus yield than on the practical feasibility of the methods applied. The European research initiative P-REX, which is coordinated by Kompetenzzentrum Wasser Berlin, is intended to assist with advancing the development of efficient technological solutions for recycling phosphorus from sewage sludge throughout Europe.
