The dairy industry in Eastern Africa is emerging, providing not only a significant contribution to the countries’ GDP, but also supporting the livelihoods of more than two million small-scale farmers. However, lacking cooling facilities hamper its further development, as many farmers live simply too far away from the market to deliver their (evening) milk before it spoils. The resulting ‘milk losses’ at farm level are estimated at 30-40% (FAO, 2003). This limits the supply of raw milk to the milk processors; while there is a growing domestic demand and milk processing plants are operating at low utilization rates due to shortages in milk supply. The solution lies in off-grid milk cooling at small-scale farms using a reliable and renewable energy source: biogas produced from cow manure.
