Demonstration of circular biofertilisers and implementation of optimized fertiliser strategies and value chains in rural communities
RUSTICA develops sustainable bio-based fertilisers (BBFs) from fruit and vegetable residues to reduce environmental impacts and enhance soil health. The project focuses on five innovative conversion processes – microbial biomass cultivation, electrodialysis, insect breeding, biochar production, and carboxylic acid synthesis – tailoring BBFs to specific crops and local waste streams. Operating across seven European countries and Colombia, RUSTICA integrates these methods with composting and bio-hubs to optimize circular nutrient recovery. The biofertilisers show promising agronomic performance comparable to mineral fertilisers while supporting soil regeneration. Although some blends require higher application rates, ongoing optimization aims to reduce costs and environmental footprints. By closing nutrient loops regionally, RUSTICA advances rural economies, promotes environmental sustainability, and delivers scalable, adaptable biofertiliser solutions aligned with circular economy principles and resilient agricultural systems.
