Abstract

The global push toward sustainable energy solutions has intensified the exploration of biomass briquetting technologies, particularly in coffee-producing regions. Coffee husk waste, an abundant agro-industrial byproduct, presents a viable renewable energy source through densification techniques. This review systematically evaluates existing research on coffee husk briquetting, emphasizing its thermal, physio-mechanical, and combustion properties. The integration of cow dung as a binder further enhances briquette cohesion, addressing challenges associated with low bulk density and inefficient combustion. The study synthesizes key findings related to environmental impact, policy implications, and technological advancements, underscoring the potential of biomass briquettes in reducing reliance on traditional fuels. While briquetting has been extensively studied, gaps remain in optimizing production parameters to enhance energy yield and emission performance. This review contributes to the discourse on biomass valorization, advocating for further research to refine briquette composition for improved sustainability.
