Bio-based fertilisers (BBFs) hold significant potential for advancing nutrient recycling and promoting sustainable agriculture, but their widespread adoption is influenced by end-user perceptions, market potentials and policy challenges. While the production of BBFs in general offers a promising avenue for sustainable nutrient management, realising their full potential necessitates concerted efforts to address economic constraints, develop fertiliser types that meets farmers demands, align regulatory frameworks, and support market development through targeted policies and stakeholder engagement. While guiding social costs for producing BBFs are higher than comparable prices for nutrients in mineral fertilisers, crop farmers have some reservations towards BBFs due to their technical qualities and are generally unwilling to pay the same for nutrients in BBFs as for nutrients in mineral fertiliser. These are some of the conclusions of research carried out under the Interreg Baltic co-financed
CiNURGi project, coordinated by Organe Institute and presented in a Technical Report on
"Market Evaluation and Review of Policy Affecting Nutrient Recycling".
