A Brewing Solution: Utilizing Spent Coffee Grounds As An Alternative Biomass Fuel.

In response to the global demand for sustainable energy, researchers explore biomass fuels like Spent Coffee Grounds (SCGs) as eco-friendly alternatives. This study compares SCG fuel pellets with commercial ones for thermal properties, aiming to establish SCGs as viable biomass fuel alternatives. SCGs, sourced from Arabica coffee ground waste, undergo pelletization using an industrial pelletizer with starch as a binding agent. The study measures moisture content, ash content, and calorific value through laboratory experiments. Statistical analyses using T-test reveal significant differences in moisture and ash content between SCG Fuel Pellets and commercial counterparts, with no significant difference in calorific value. SCG Fuel pellets excel in moisture and ash content, making them viable alternatives. The study recommends further research on the industrial performance and scalability of SCG fuel pellets. This research contributes valuable insights into repurposing coffee production waste, offering an environmentally friendly alternative. It supports efforts to diversify the world's energy portfolio and mitigate the environmental impact of conventional fuel sources. [ABSTRACT FROM AUTHOR]
