Abstract:A technical and socio-economic feasibility study of biomass briquette production was performed in Iloilo City, Philippines, by integrating a registered group of the informal sector. The study has shown that the simulated production of biomass briquettes obtained from the municipal waste stream could lead to a feasible on-site fuel production line after determining its usability, quality and applicability to the would-be users. The technology utilized for briquetting is not complicated when operated due to its simple, yet sturdy design with suggestive results in terms of production rate, bulk density and heating value of the briquettes produced. Quality briquettes were created from mixtures of waste paper, sawdust and carbonized rice husk, making these material flows a renewable source of cost-effective fuels. An informal sector that would venture into briquette production can be considered profitable for small business enterprising, as demonstrated in the study. The informal sector from other parts of the world, having similar conditionality with that of the Uswag Calajunan Livelihood Association, Inc. (UCLA), could play a significant role in the recovery of these reusable waste materials from the waste stream and can add value to them as alternative fuels and raw materials (AFR) for household energy supply using appropriate technologies.

“…As suggested by [7], [8], the composition of those elements in biomass has an impact on the characteristics of fuel combustion, as the total mass of a fuel declines during a volatile combustion phase when the ratio between hydrogen and carbon increases and to a lesser extent when the ratio between oxygen and carbon ratio rises. The amounts of nitrogen, sulfur, and chlorine determine the emission level of noxious gases.…”

Abstract-Some residues from industries and households were used to turn into briquettes. In this research, waste paper and coffee residues could be practically used to produce fuel briquettes by adding starch as a binder before performing a molding cold process. The optimal ratios between waste paper and coffee residue were considered to be 70:30, 60:40, 50:50, 40:60, and 30:70.Their calorific values ranged from 3,708.5 to 4,347.1 cal/g. These values were almost equivalent to the amount of the heat from the firewood. The study also discovered that the briquettes rendered their moisture content (7-9%), the amount of ash (3.8-8.5%), and the amounts of fuel elements (45.56% carbon, 6.48% hydrogen, 45.41% oxygen, 0.75% nitrogen, and 0.08% sulfur) within the acceptable values of biomass standards. The briquettes were readily molded, not easily shattered, and inflammable with low amount of smoke and odor. Therefore, the production of fuel briquettes from waste paper and coffee residue could be one of the viable alternatives for community energy generation.Index Terms-Coffee residue, fuel briquettes, waste paper.

“…Densification of biomass under high pressure brings about mechanical interlocking and increased adhesion between the particles, forming intermolecular bonds in the contact area. In the case of biomass the binding mechanisms under high pressure can be divided into adhesion and cohesion forces, attractive forces between solid particles, and interlocking bonds [6].…”

“…The central hole incorporated into the briquettes produced by a screw extruder helps to achieve uniform and efficient combustion and, also, these briquettes can be carbonized. Table: 2 show a comparison between a screw extruder and a piston press [5,6]. As it has been seen from the above comparison the mechanical or hydraulic piston press technology is rather complicated and high initial investment and some technical infrastructures are required.…”

“…In general, energy use in drying consists of latent heat of evaporation, sensible heat, heat lost by exhausting of air and heat lost by convection and radiation from the dryer's walls, and other heat losses such as leaks [6]. Assumptions: Only 50% heat going for preheating The remaining 50% accounted for by losses in flue gases (40%) and losses due to radiation in oil circulating system (10%), 90% combustion efficiency of furnace which takes into consideration the radiation losses from furnace and uncombusted fuel, Ambient temperature 24 0C Heat required in pre-heater If it assumes 90 % furnace combustion efficiency, the amount of energy required in furnace for pre heating is: If it assumes to use a eucalyptus saw dust briquetting briquette or any biomass with calorific value of 2500 Kcal/kg, the amount of briquetting required to pre heating sub system is calculated as follow:…”

Biomass briquetting is a process which converts agro residue and saw dust materials with low bulk density into a uniform size and more convenient households or industrial fuel product. The major advantages offered by biomass densification are related to handling improvement and increasing calorific value per unit volume. In general this process offers energy generation opportunity from any biomass residue. Maichew Particle Board Factory generates a huge amount of dust particles from its different lines which recovered using different cyclones. But this recovered waste doesn't use as a fuel for boiler or dryer and also not yet convert to any valuable product. It is simply disposed to the environment. Therefore, the objective of the project was to study an integrated briquetting plant for Maichew Particle Board Factory which converts the waste dust particle in to valuable product. This case study involved the overall energy review of Ethiopia and briquetting process in detail. According to the selection of appropriate technology which converts the eucalyptus dust to high quality briquette fuel screw press extruder with a pre heater and heated die coils has been chosen. In addition the amount of energy required to convert the dust particle to briquettes is also evaluated. Based on the results of this study, the economic evaluation of the integrated briquetting plant for Maichew Particle Board is feasible besides to its socio environmental benefits. It is an investment which can recover its capital with almost two years.
