Biomass Charcoal Briquetting Currently there is a strong worldwide interest in the development of technologies that allow the exploitation of renewable energy sources, both for environmental reasons (release of pollutants and fossil reserves depletion) and economical ones. India is the world's sixth largest energy consumer, consuming about 3 per cent of the world's total energy per annum. Plant biomass can be converted into charcoal briquettes by igniting the biomass under low oxygen conditions. These briquettes have higher calorific value and burning capacity than using plant biomass directly. DST core support has been working on an improved Biomass charcoal briquetting technology in which different plant biomasses are converted into charcoal briquettes and their calorific value and burning properties studied. More studies were conducted during the past year for the improvement and standardization of the technology and as a part of it different agricultural wastes such as Casuarina leaf litter, Prosaphis twigs, Ipomoea stem, Lantana camara stem, Eucalyptus leaves and coconut leaves were used as biomass source. Carbonization was carried out at different temperatures from 100°C to 600°C for optimizing the char yield and different cost effective binders such as starch, rice powder, clay etc. were also tried. The fuel br iquettes produced through briquetting machines (calorific values - max.6500 kcal/kg and min.4500 kcal/kg) were tested at local teashops, laundry and small hotels in Chennai for alternative fuel. The biomass charcoal briquetting technology has been standardized at MCRC and disseminated to various beneficiaries such as farmers, individuals, unemployed people, NGOs and college students. As per the DST CORE programme objectives, the biomass charcoal briquetting technology will be disseminated to 10 selected villages from Tamil Nadu. The dissemination work is in progress.
