The environmental impact of traditional cremation practices, which rely heavily on firewood, has necessitated the exploration of more sustainable alternatives. This study investigates the use of biomass briquettes, made from agricultural waste, as a replacement for wood in the cremation process. The prea mble discusses the detrimental effects of wood-based cremation, including deforestation, air pollution, and high costs. The study utilized various types of biomasses, including rice husk, coconut shells, and sawdust, to manufacture briquettes. The briquette-making process involved shredding the raw materials, drying to reduce moisture content, and compressing into dense logs using a briquette machine. The properties of the briquettes were analyzed, focusing on density, moisture content, ash content, organic content, and calorific value. The study found that the density of agro waste varied from 79 kg/m3 to 280 kg/m3, and moisture content ranged from 8.06% to 25.47%. Groundnut shell briquettes showed the least moisture content, making them the most suitable for cremation. The ash content of the samples indicated efficient combustion, with soybean and groundnut shells having the lowest ash content. Organic content varied between 45% and 92%, and calorific values ranged from 2117 cal/g to 4377 cal/g. The research demonstrated that biomass briquettes are a viable and eco-friendly substitute to firewood for cremation, reducing deforestation and emissions. The study concluded that the optimal briquette composition and manufacturing process significantly improve combustion efficiency and environmental sustainability. Future work will involve field trials to determine the exact quantity of briquettes required and the burning time for complete cremation.
