The Circular Bionutrient Economy Network (CBEN) is building the research, policy and operational basis for nutrient-recovery from underutilised organic resources such as crop residues, market waste, and livestock and human excreta, to produce fertilisers and soil amendments that farmers in East Africa can use to improve soil health, livelihoods and food security. CBEN unites an international community from East Africa and beyond in a robust community of purpose by convening strategic working groups, conferences and field visits. CBEN builds strong collegiality principled in democracy, transparency and collaboration among researchers, NGOs, industry partners and government representatives.
