This report, produced in connection with Task A1.2 of the Interreg Baltic co-financed CiNURGi project, presents ”Suggested standards for fertilisers to sustainably recycle nutrients”. The report proposes some definitions to delineate the scope for the suggested standards, which shall have the purpose to raise the valuation of bio-based fertilisers and crop producers’ willingness to pay for them.The concrete suggested standards include notably an algorithm whereby bio-based fertilisers and nutrient rich wastes are distinguished from soil improvers and nutrient poor wastes. A paradigm shift is furthermore proposed when it comes to the regulation of soil pollutants, which is suggested to happen on basis of Allowed Field Spreading amounts, and that spreading of more pollutant on soils that are already registered by the EU Soil Observatory as unhealthy for that pollutant shall be banned.
