Both in the Netherlands and in Flanders, large amounts of manure surpluses are realized every year in animal husbandry. These manure surpluses are partly exported to neighbouring countries. At the same time, farmers in the Netherlands and Flanders must annually purchase large quantities of expensive mineral fertilizers.

The Interreg project ‘NITROMAN’ wants to investigate in the Flemish-Dutch border region whether mineral fertilizers can be extracted from the available manure surpluses. This would allow manure surpluses from local livestock farms to be processed on site into fertilizers for agriculture. The project focuses on the processing of liquid manure fraction from pig and cattle manure. NITROMAN wants to recover considerable amounts of nitrogen, potassium and water through two innovative techniques from this liquid manure fraction. Nitrogen and potassium can then be used as fertilizer in agriculture. The Latin term for nitrogen is ‘nitrogenium’. Hence, the project was given the name NITROMAN.

Pilot installations will be installed at a number of livestock farms across the border region. NITROMAN will also develop a calculation tool. This allows companies to calculate whether circular manure processing is feasible, and if so, which of the two techniques offers them the most benefit. The collected knowledge will be widely distributed to the agricultural sector. Moreover, interested companies will be able to attend demonstrations so that they can get to know the benefits of circular manure processing from up close.

On this page all information about the project will be bundled. You can also visit us on Facebook.

NITROMAN is funded within the Interreg V Flanders-Netherlands program, the cross-border cooperation program with financial support from the European Regional Development Fund. More info: www.grensregio.eu.
