Case study on Safi Organics, one of the largest producers of rice in Kenya. The company aims to reverse declining agricultural yields, improve the income and food security of local farmers, and provide opportunities for local youth. Safi Organics created an agricultural value chain from the local organic waste stream. Using an open source technology, the enterprise produces valuable agricultural inputs such as fertiliser and soil treatments designed to meet local conditions.  Waste rice husk is collected from farmers and processed into bio char, the bio char is then stored, processed, and a local enzyme is added to enable microbial growth. The fertiliser and soil treatments are sold back to the farmers directly or through agents.
