Abstract:

A case study for Elabered estate, a farm located 63km north-west of Asmara, Eritrea was conducted for a biogas plant implementation. Cow dung was taken to be the main feedstock for the biogas digester. The total quantity of manure estimated was 3000kg out of 300 cows per day. Having this, 173m3/day biogas production was estimated. Assuming the produced biogas to be upgraded up to 95% CH4 content the total energy generation potential is equivalent to 1089.7kWh/day. As the energy requirements for ploughing harrowing and cultivating 100ha farm was calculated the maximum daily energy requirement was 512.58kWh. In comparing the daily farm energy needs and biogas energy potential, it is inferred that the proposed biogas reactor energy output can sustainably run the selected farming activities. The remaining energy can be diverted to self-powering the biogas plant accessories such as collecting manure and distributing digestate to the field, transporting feed to the dairy farm and other miscellaneous energy consumptions.
