Rice Husk Energy Technologies in Bangladesh

Bangladesh is an agriculture based country and the major food comes from rice. The rice plant also produces a significant amount of byproduct which is used as energy. The production of rice husk is steady and increasing in trend in Bangladesh. This biomass energy is playing a significant role in the country energy use. This study was conducted to focus on the improvement of rice husk energy and constraints for technologies dissemination in Bangladesh. The performances of the rice husk energy technologies were studied. The benefits of the use of rice husk energy technologies were analyzed and the constraints to its dissemination were found out during this study. The main consumer of the rice husk energy is the rice milling sector. About 70% of rice husk energy is consumed by the rice parboiling system. The wastes of rice husk energy can be reduced by replacing the improved system and CO level in flue gas can be reduced as well. The surplus rice husk is converted to rice husk briquette fuel which is used for cooking in small restaurant and poor household sector. The solid fuel is used as an alternative of wood fuel. The rice husk briquetting could generate employment and play a great role to reduce the CO2 reduction. Several constraints were identified for the dissemination of rice husk energy technologies viz. policy and regulation; official recognition, attitudinal barrier, loan facility, ownership, raw material availability etc
