“…This was attributed to the fact that molasses is constituted mainly of sucrose [32] which does not have high calorific value as compared to wood char. A similar behavior had also been observed when molasses was used as a binder in rubber wood, corn cob, eucalyptus and bamboo sawdust [20]. On the other hand, it was observed that gross calorific value slightly decreased as drying temperature increased.…”

“…Numerous research [12][13][14][15][16] have been done on briquette production and characterization. A lot of efforts have been made to study briquettes from different sources [17][18][19][20][21]. Properties such as volatile matter, calorific value, relaxed density, compressed density, ash content, durability, fixed carbon, dimensional stability, compressive strength, etc., vary with raw material, binder type, compacting pressure and temperature.…”

Physical and thermal properties of briquettes produced by recycling charcoal dust under different processing conditions have been reported in this study. The main aim was to investigate the effects of the binder and processing conditions on the properties of briquettes. The effect of adding molasses binder on combustion properties of the briquette was first assessed. Then by fitting experimental data, mathematical models to predict gross calorific value, ash content, moisture content, relaxed density and shatter index with respect to binder mass fraction, drying temperature and compaction pressure were developed. All briquettes properties were predominantly affected by amount of molasses used. Molasses mass fraction increment in briquette results in significant increment in ash content, moisture content, relaxed density and shatter index and significant reduction in gross calorific value. Drying temperature did not have major influence on briquette properties except moisture content. Compaction pressure (50-150 MPa) used in this study had negligible influences on all briquette properties. Therefore, such high pressure which involves energy consumption is not necessary during production of charcoal dust briquettes. Optimized values of gross calorific value and shatter index were 29.031 MJ/kg and 80.363%, respectively, for 50 MPa compaction pressure, 29.512 °C drying temperature and 10% molasses mass ratio.

“…The percentage of fixed carbon content in briquettes is a critical factor that influences the calorific value of fuel [36]. As the percentage fixed carbon of the homogenous particle briquettes (A. leiocarpus, ground shell, corn cobs) is less than that of the heterogeneously mixed wood and agro wastes briquettes, the specific heat of combustion value is more than that of the heterogeneously mixed wood and agro wastes briquettes.…”

This study investigated the physical and combustion properties of briquettes produced from agricultural wastes (groundnut shells and corn cobs), wood residues (Anogeissus leiocarpus), and mixture of the particles at 15%, 20%, and 25% starch levels (binder). A 6 × 3 factorial experiments in a Completely Randomized Design (CRD) was adopted for the study. The briquettes produced were analyzed for density, volatile matter, ash content, fixed carbon, and specific heat of combustion. The result revealed that the density ranged from 0.44 g/cm3 to 0.53 g/cm3, while briquettes produced from groundnut shells had the highest (0.53 g/cm3) significant mean density. Mean volatile matter and ash content of the briquettes ranged from 24.35% to 34.95% and 3.37% to 4.91%. A. leiocarpus and corn cobs particles had the lowest and highest ash content, respectively. The briquette fixed carbon and specific heat of combustion ranged from 61.68% to 68.97% and 7362 kcal/kg to 8222 kcal/kg, respectively. Briquette produced from A. leiocarpus particles had the highest specific heat of combustion. In general, briquettes produced from A. leiocarpus particles and mixture of groundnut shell and A. leiocarpus particles at 25% starch level had better quality in terms of density and combustion properties and thus are suitable as an environmentally friendly alternative energy source.

“…The results identify that it is possible to produce pellets from biomass which were milled into small particles less than 5 mm by using the hydraulic press. Further investigation shows that manual hydraulic press may be also successfully used for bio-briquettes production from selected biomass wastes [17]. Agricultural products and residues may also be used for biogas [18].…”

Post-mining peaty lands were formed as a result of peat extraction on drainage wetlands areas. After peat extraction has finished, the biggest problem is to use these lands for other purposes. This type of soil is very heterogenic, poorly drained, with massive structure and poor contents of nutrients. Thus it is very problematic to grow traditional agricultural crops that have special requirements for soil fertility on those areas. The area of post-mining peaty lands in Belarus alone is about 200 000 hectares. One of the perspective directions of post-mining peaty land use is re-wetting and production of biomass for energy purposes. The goal of our research was to estimate cost of biomass of natural grass and willow wood from short rotation coppice (SRC) plantations which may be used as feedstock for pellet production. The dominant wetland species were common reed, cattail and sedges. SRC plantation was planted on degraded soils. The prime cost of biomass which was produced on the base of natural grass was from 10.4 euro per ton to 13.2 euro per ton, depending on technology. The prime cost of willow biomass was 24.1 euro per ton. Introduction of taxes will increase cost of biomass by approximately 60 %. The calculation of economic efficiency identified that biomass as a feedstock for pellet production on post-peat mining areas may be a profitable direction for peat factory function and providing the sustainable development of local communities. Additional profit may be obtained as a result of saving carbon quotas. The share of CO2 emissions from fossil fuel for grass biomass production is about 2 % from the total volume of CO2 during renewable biomass utilization for energy and for chips production from willow wood - 6 %. The diversification of biomass sources enables to use feedstock for a pellet line in the winter and spring which is in the heating season.
