| Summary, etc | The study aims to develop a biomass briquette from mixed corn stalks and ground coffee with waste paper as binder. The specific ratio of mixed corn stalks and coffee grounds tested are the following: 70:0, 50:20, 35:35, 20:50, and 0:70 and 30% w/w paper pulp as a binder was added in the mixture. A densification pressure of 25 kN/mm2 was applied in the development of compact briquettes. The physicochemical properties namely moisture content, volatile combustible matter, fixed carbon, and ash content, thermal properties such as calorific value, ignition time, and burning rate), and mechanical properties such as shatter resistance, water resistance, and bulk density were determined. In terms of physicochemical properties, the mixture containing 20% corn stalks, 50% coffee grounds and 30% paper pulp aligns with the accepted range for biomass briquettes regarding fixed carbon content (60-75%), moisture content (8-12%), volatile combustible matter (20-25%), and ash content (3-20%). In ignition time the best is the mixture containing 70% corn stalks and 30% paper pulp, having the shortest time of ignition which is 2.1191 minutes and for the burning rate, the mixture containing 70% coffee grounds and 30% paper pulp is the ideal because it has a low burning rate. In terms of mechanical properties, the mixture containing 70% coffee grounds and 30% paper pulp has the highest bulk density which implies that it is more compact and occupies a smaller volume compared to the other mixes; the mixture containing 70% corn stalks and 30% paper pulp has the highest percentage of 98.79% in terms of shatter resistance, mixtures with corn stalks percentage ranging from 20-70% and coffee grounds percentage ranging from 0- 50% fell within the standard range and have a significant difference with the mixture containing 70% coffee grounds and 30 which suggests that these mixtures are the favorable briquette samples in terms of shatter resistance; the mixtures containing 70% corn stalks and 30% paper pulp and 50% corn stalks, 20% coffee grounds, and 30% paper pulp has the highest percentage of 98.79%. Keywords: Biomass Briquettes, Corn Stalks, Coffee Grounds, Calorific Value, Ignition Time, Burning Rate. |
