The Evaluation of Fuel Briquetts Produced from Municipal Wastes

Naruephat Tangmankongworakoon and Patcharee Preedasuriyachai

Abstract—This study aimed to turn municipal wastes from industries and households into fuel briquettes, namely coffee residue, tea residue, and fat dregs. The experiments were set up in three groups of the following mixture: Group I consisted of fat dregs and coffee residue; Group II comprised fat dregs and tea residue; Group III contained tea residue and coffee residue. The study discovered that in Group I and Group II, the ratio of 50:50 provided the highest heating value of 6,493 cal/g (Group I), and 5,727 cal/g (Group II), while in Group III, the ratio of 30:70 provided the highest heating value of 4,786 cal/g.The study also discovered that the biomass wastes rendered their moisture content (3-8%), the amount of ash (1-5%), volatile matter (71-87%) and fixed carbon(7-15%).The study also found that the fuel briquettes produced from Group I and Group II had desirable characteristics to produce fuel briquettes for households since they were easily moulded, inflammable with low amount of smoke and odour while those produced from Group III were easily moulded, yet hardly inflammable with high amount of smoke. Responses from the survey indicated that briquettes made from fat dregs mixed with coffee residue were easy to ignite, left no stains on hands, burned for a long time, and had good heat output. The respondents also commented that the briquettes did not give off sparks and had less smoke and ash content than those of charcoal they normally used.

Index Terms—Coffee residue, fat dregs, fuel briquettes, municipal wastes, tea residue.
