Building on the initial findings of the environmental benefits of using biomass briquettes for cremation, this part of the study focuses on field trials and optimization of the briquettes’ performance in real-world conditions. The preamble highlights the necessity of transitioning from wood-based cremation to biomass briquettes to mitigate deforestation and reduce emissions. The study conducted on-field trials at various crematorium sites, assessing different configurations and inclinations of the base plates to optimize briquette consumption and combustion efficiency. Data collection included measuring the volume and weight of briquettes required, time taken for complete cremation, and emissions produced during the process. The trials revealed that increasing the inclination angle of the base plate decreased the volume of briquettes required, thereby optimizing fuel usage. The density and calorific value of the briquettes were key factors influencing the combustion process. The study also measured the moisture, organic, and ash content of the briquettes, with findings indicating that lower moisture and ash content led to better combustion and reduced emissions. The field trials confirmed the laboratory results, demonstrating that biomass briquettes can effectively replace firewood in cremation practices. The study emphasized the importance of proper briquette composition and manufacturing processes to ensure complete and efficient combustion. The use of biomass briquettes was shown to significantly reduce the environmental impact of cremation, making it a sustainable and cost-effective alternative. Future research will explore further optimization techniques and broader implementation across different regions.
