Tanzania has a high rural population, of which many rely on off-grid diesel generators to produce electricity. The focus this paper is assess if the waste biomass residues in have sufficient energy potential renewable electrical for small-scale electricity generation using coupled with anaerobic digestion (AD) and/or gasification. gaseous fuel produced can then be used substitute dual gen-sets; thus, providing more affordable whilst reducing dependency fossil fuels. streams estimated are those arising from agriculture, forestry, livestock, and urban human waste. To answer question, potentials each these quantified, followed by further calculations determine capacity per stream based overall efficiencies 10 25%. results show that combined an 385 PJ (for base year 2018) generated 26,924 kilotonnes (kt). Collectively, at least 1.2 times nationally 2018 AD gasification gen-set engine.
