Abstract
Over-dependency on traditional energy sources, particularly in African countries, significantly contributes to deforestation and carbon emis-
sions. Agricultural waste presents a suitable alternative to conventional energy through bio-briquettes; however, they are underutilized. This
study evaluated bio-briquettes’ mechanical properties, including abrasion resistance, impact resistance, and water penetration resistance,
made from carbonized coconut husks using cassava peels, banana peels, and potato peels as binders. Briquettes bound with potato peels had
the highest impact resistance of 96.55%, 96.43%, and 95.26% for ratios 80:20, 70:30, and 60:40, respectively. In comparison, cassava peel-bound
briquettes exhibited moderate impact resistance, increasing to 87.71% at a 60:40 ratio. In contrast, banana peel binders had the lower impact
resistance, with a maximum impact resistance of 76.72%. Abrasion resistance followed the same trend; in briquettes bound with potato peel,
abrasion resistance increased up to 88.69% at 60:40, while banana peels performed the least effectively; the abrasion resistance was 70.09%
at 60:40 ratio. Water penetration resistance improved with the increase in binder concentration, with potato peel-bound briquettes reach-
ing 79.82% at 60:40, while cassava and banana peel-bound briquettes showed complete disintegration at an 80:20 ratio. Overall, this study
indicates that agricultural waste functions as an efficient binder in briquette production, supporting sustainable household energy use. This
study contributes to renewable energy innovation, waste valorization, and climate change mitigation by promoting sustainable alternatives to
traditional biomass energy.
