Abstract
Tea wastes are generated on a daily basis in tea estates and these pose an environmental threat due to greenhouse gases emissions yet these presents an opportunity of generation of biomass briquettes. In this study, tea wastes were converted to bio char at 300°C and ground to a particle size of less than 8mm. The bio char was compacted to form briquettes with a calorific value of 22-24 MJ/kg and moisture content of less than 10%. The tea waste briquettes can be integrated back into the tea manufacturing system as a co firing agent with coal or as an independent energy generator.
