Frits Elferink, NBP Handelsbureau B.V., presented the Glatt PHOS4green technology as an innovative solution for phosphorus recovery from sewage sludge ashes and its residue-free conversion into ready-to-use, commercially available standard phosphorus fertilizers. The Nutrient Platform is a cross-sectoral network of Dutch organizations that believe in a pragmatic approach towards nutrient scarcity. By recovering phosphorus from the ‘waste’ streams and turning it into valuable new products, not only the environment is improved but also the phosphorus cycle is closed.

In some regions, the departure from agricultural sewage sludge use is coming faster than the sewage sludge ordinance requires. This was demonstrated at the sewage sludge specialist forum held by the Huber company in Berching, where a good 300 participants discussed concepts for sewage sludge utilization, phosphorus recovery and inter-municipal cooperation.
