With increased technology and economic opportunities, demand for energy and fuels in developing countries is growing exponentially to run processes and improve lifestyles, but rural areas may not have access. It is thus important to identify possible sources of energy for developing rural areas, especially those sources which are renewable and locally produced. The objective of this study was to develop a computer model to assess the viability of developing integrated biofuel production systems using biomass materials specific to Mozambique and India. The models considered various system capacities and production scenarios. Estimates of processing costs, along with other economic factors, were determined through techno-economic analysis, and environmental impacts were determined through life cycle assessment. Biofuel production on a farm scale was determined for a biodiesel, ethanol, and combined production system, with various capacities. Eighteen scenarios were created and tested. It was determined that larger capacities were more profitable per unit of biofuel, and the capacities exhibited economies of scale. A combined system has proven to increase profits, and production of 10L/day, in a combined system is the most profitable of the India based scenarios. In Mozambique based scenarios, production of 10L/day, in a combined system is the second most profitable option, with the biodiesel scenarios beating it by $0.06 cents per year per liter of biofuel produced. Environmentally, the best scenarios are based in Mozambique because of the use of hydroelectric power instead of traditional coal powered electricity. The best environment option in India based scenarios is the 0.125L/hour (1L/day) scenario, producing biodiesel. This system gives off only 10.08 kg of CO2 equivalent per year. This study has provided a starting point for assessment of the farm scale production of biofuels in developing countries.
