WalNUT- Closing waste water cycles for nutrient recovery

WalNUT aims to develop technological solutions for redesigning nutrient supply chains from wastewater and brine. The project will carry out 5 pilot demonstrations. Cetaqua will develop a production system for Smart Biofertilisers based on an Optiblend system that combines nitrogen (ammonium salts), phosphorus (struvite) and potassium with plant growth stimulants (PGBs) of biological origin.

Duration: February 2021 - September 2026
Coordinator: CARTIF
Partners: CARTIF, Assemblée permanente des Chambres d’agriculture, AQUAFIN, CETGAL, UGENT, ICONS, NTUA, Universidad del Sur de Dinamarca, TERRA, Universidad de Copenhague, Universidad de Turín, VEOLIA, Universidad de Coimbra
