“…The degree of compaction achieved for all the briquette types ranged between 343-436%. These values were found to be higher than the 231%, 203%, 202% and 219% reported by Srivastava et al [17] for cauliflower + cabbage leaves, coriander stalk + leaves, field beans and green bean pods, respectively. The high percentage increase in density from the original bulk density was because the particle sizes of the cabbage and carrot residues were reduced to the point of achieving higher compaction [14].…”

Abstract:The conversion of biomass to high-density briquettes is a potential solution to solid waste problems as well as to a high dependence on fuel wood in developing countries. In this study, the potential of converting vegetable waste to briquettes using waste paper as a binder was investigated. A sample size of 30 respondents was interviewed using a self-administered questionnaire at the D-line fruit and vegetable market in Port Harcourt, Nigeria. Carrot and cabbage leaves were selected for briquetting based on their availability and heating value. This waste was sun-dried, pulverized, torrefied and fermented. Briquettes were produced with a manual briquette press after the processed vegetable waste was mixed with waste paper in four paper:waste ratios, i.e., 10:90, 15:85, 20:80 and 25:75. The moisture content, densities and cooking efficiency of the briquettes were determined using the oven-drying method, the water-displacement method, and the water-boiling test, respectively. There was no observed trend in moisture content values of the briquettes, which varied significantly between 3.0% and 8.5%. There was no significant variation in the densities, which ranged from 0.79 g/cm 3 to 0.96 g/cm 3 for all the briquette types. A degree of compaction above 300% was achieved for all the briquette types. Water-boiling test results revealed that 10:90 paper:sun-dried cabbage briquettes had the highest ignitability of 0.32 min. Torrefied carrot briquettes with 25% paper had the least boiling time and the highest burning rates of 9.21 min and 4.89 g/min, respectively. It was concluded that cabbage and carrot waste can best be converted into good-quality briquettes after torrefaction.

“…True densities of the biomass and briquettes (dry basis) were determined using the mass and volume relationship [26]. The degree of compaction of the briquetted materials was calculated as percent increase in true density over bulk density of ground residues, as in Srivastava et al [17].…”

“…Briquetting biomass is a densification process which is able to produce a compact material with higher energy per unit volume [6,7]. Additionally, the densification improves the handling and reduces the transportation cost, producing a uniform, clean and stable fuel [8,9].…”

“…In spite of the briquetting process is a technology mainly employed to compact biomass [7,8,10,[28][29][30], briquettes made of refuse derived fuel (RDF) [31], textiles [32] or mixtures of plastic wastes [33,34] have been also produced. The combination of biomass and high heating values wastes present two important benefits: on the one hand, the maximization of the use of the energy sources and, on the other, the potential solution for plastic wastes disposal [6,[35][36][37].…”

Abstract:In this study, the physical properties of briquettes produced from two different biomass feedstocks (sawdust and date palm trunk) and different plastic wastes were investigated, without using any external binding agent. The biomass feedstocks were blended with different ratios of two WEEE plastics (halogen-free wire and print circuit boards (PCB)) and automotive shredder residues (ASR). The briquettes production is studied at different waste proportions (10-30%), pressures (22-67 MPa) and temperatures (room-130 ˚C). Physical properties as density and durability rating were measured, usually increasing with temperature. Palm trunk gave better results than sawdust in most cases, due to its moisture content and the extremely fine particles that are easily obtained.
