Techno-economic analysis of biomass waste based pellet production in Bangladesh

Abstract

his thesis involves with the techno- economic analysis of biomass waste pellet production in Bangladesh. As an agricultural country along with a larger population we have lots of biomass waste. 75% of energy comes from biomass in rural area we found that agricultural waste and residues are used in a non-efficient and non-hygienic way. Mainly this energy consumption is happened in rural indigenous cooking system with only 8-12% efficiency. The main problem with that biomass is less density and moisture content. By palletizing we can solve those problems. In this thesis, it has been put some statistical data and analysed the data reflecting the possibility of establishing power generation unit using biomass waste pellet.we also introduced a new raw material mix, caddies with saw dust. Our test production was successful. We tested our experimental pellet and found very suitable as a fuel with calorific value 4235.4 kcal/kg and density index 0.96. The pellet production also found economically feasible. By using pellet we can solve our energy crisis, assuring hygiene in rural cooking and save the entire environment.
