Blends of groundnut shell and coal were formulated in various ratios (100:0, 90:10, 85:15, 80:20, 75:25, and 70:30) with starch and calcium hydroxide as binders. The results showed that the ash composition of the coal was higher than that of the groundnut shell and that toxic pollutants such as As and Pb were more prevalent in coal than in the groundnut shell. Additionally, the sulphur content of coal was much higher than that of groundnut shell, indicating a higher tendency for the coal to emit sulphur (IV) oxide during combustion. However, the groundnut shells were found to have a higher cellulose and lignin content, making them a suitable biofuel source. Coal's high carbon content makes it a valuable fuel for electricity generation. The groundnut shell-coal blended briquettes had a lower moisture content (ranging from 10-30%) and ash content (ranging from 10-30%) than the control. As the biomass content in the briquettes increases, the density of the samples also increases, making transportation easier. The ignition time of the briquettes decreases with an increase in biomass content, and the compressive strength of the briquettes decreases due to less packed coal particles. The time taken to evaporate water decreases as the biomass content increases. This study presents that using groundnut shell biomass in coal briquettes is a promising alternative energy source, as it reduces the environmental impact of traditional coal usage while providing a cleaner and more sustainable fuel option.
