Biomass briquettes have been used as an alternative to firewood and charcoal. In this study, production of briquette from ground coffee waste will be carried out to determine its feasibility as fillers when mix with two sets of binders namely rice husk and waste papers. Torrefaction of coffee waste is conducted as a pretreatment process to determine its effect on the properties of torrefied coffee waste briquette. The ground coffee waste is mixed with the binder in ratio of 50:50 for each briquette combination. Paper waste binder shows its effectiveness with coffee waste the mixture during expansion test, squeeze test and shake test, producing strong and combustible briquette. Composition mixture of filler to binder influenced significantly in which the resulting efficient water boiling test, heating value, percentage of fixed carbon, ash content and volatile matter from composition 80:20 yield better result than composition 70:30. Torrefaction temperature was varied from 260 to 290 and the reaction time was studied between 30 - 60 minutes. The torrefied coffee waste briquette at both temperatures shows better combustive properties than the non torrefied briquette. During water boiling test, all briquettes unable to burn until boiling point, however the torrefied coffee briquette managed to reach maximum temperature of 70 within 30 minutes.
