Current Research

Sustainability is one of our time’s greatest challenge, especially when it comes to the recycling of naturals resources. Even though phosphorus is an essential nutrient and phosphates are main components of industrial fertilizer, almost half of the phosphate is currently in a "one-way street". Our waste water is one mayor sink for phosphates, where they mostly accumulate in sewage sludge. But due to the presence of pollutants such as heavy metals, pharmaceutical residues or industrial chemicals, sewage sludge cannot be used as a fertilizer directly. The aim of the project P-XTRACT is developing a regional recycling strategy for phosphates accumulated in sewage sludge and optimizing the resulting P-fertilizer product. 

Through greenhouse experiments with the newly established phosphorus recycling fertilizers, I would like to investigate the real efficiency of these P recycling fertilizers, as well as their effects on above- and below-ground functional plant traits.
