The project ReFARM of Wetsus and funded by EIT Climate-KIC aims to pilota combination of anaerobic digestion with bio-crystallisation to treatdairy manure and separate nutrients for recycling. Manure is pre-treatedwith a screw-press into a thin and a thick fraction. The thick fractionhas a low nutrient content and can (potentially) serve as a soilamendment to increase organic matter. The thin fraction, containing80-90% of the phosphorus in dairy manure, will go to a 4.5 m3 pilotup-flow anaerobic sludge bed (UASB) reactor, from which methane andcalcium phosphate are recovered. Calcium phosphate precipitation in thereactor will be biologically induced. The effluent of the UASB reactorcontains high concentrations of nitrogen and can potentially to betreated with an electrochemical process to recover nitrogen as ammonium.

ReFARM is funded by the EU?s European Institute for Innovation and Technology (EIT) under Climate-KIC. The project brings together three Dutch partners: WETSUS, Mulder Agro and Oosterhof Holman.

SHORT ABOUT THE PROJECT

Project Industrial animal farms in the Baltic Sea Region - sustainable practices to reduce nutrient loads is a part of a long-term campaign of the Coalition Clean Baltic and Green Federation "GAJA", aiming to reduce the negative impact of large-scale animal production on the environment and local communities in the Baltic Sea Region, particularly by reducing nutrient run-off into the sea. The project is part-financed by the European Union. This website reflects only the view of the Coalition Clean Baltic.
