Abstract

ABSTRACT Global energy demand continues to increase owing to advancements in key growth sectors of Economies. Transportation-related emissions resulting from petroleum use account for 23% of total energy-related CO2 emissions. Biofuels including biodiesel are renewable substitutes for transportation fuels that have attracted global interest. This paper reviewed existing literature on technological, economic, and life cycle environmental aspects vital for assessment of the viability of production of second-generation biodiesel including the B10 blend advocated for Uganda. The quantity of biodiesel required to fulfil a B10 blend for Uganda’s downstream petroleum sector is one hundred million litres per annum. To meet this demand, 50,000 ha of land is required for cultivation of biodiesel feedstocks against the available 6,900,000 ha. Jatropha, castor, and croton, offer agronomical advantages. Biodiesel produced from these feedstocks through transesterification, should conform to ASTM D6751/EN14214 standards. Physicochemical, economic, and environmental assessments are vital to confirm its techno-economic viability.
