The study was conducted at the Cavite State University, Indang, Cavite from August to February 2000. This study aimed to recycle agro waste materials into charcoal briquettes for fuel, to determine the quality of briquettes from agro waste materials, and to determine the best mixture proportion of rice hull and coffee pulp that produced good quality charcoal briquettes.
The coffee pulp and rice hull were mixed with a binder (cassava starch) in the desired proportion of 9:1 (9 parts agro waste: I part cassava starch). The mixture was molded using the briquetting machine developed by the College of Engineering.
The resulting products were cylindrical briquettes, 3.2 cm. diameter and 7 cm. in length. The briquettes were dried up for 3 days weeks to improve the crushing strength.
A mixture proportion of 25% rice hull and 75% coffee pulp produced the best result in terms of numbers of briquettes produced, burning characteristics and durability.
The cost of producing the briquettes is P 17.50 per kilogram.
