“…For the first time, three technology scenarios, including conventional pellets (CP), moderately torrefied pellets (TP1), and severely torrefied pellets (TP2), were compared based on the optimum total production cost at the upgrading depot's exit gate. content range of 6% to 15% was recommended in order to produce pellets with low elongation and high durability [24][25][26]. For CP, biomass was assumed to be dried by rotary dryers to a moisture of 13 wt.% , equaling the equilibrium moisture in pellets if the relative humidity is 70%.…”

In the present study, the biomass upgrading depot capacity and biomass feedstock moisture were optimized to obtain the minimum production cost at the depot gate for the production of woody biofuels. Three technology scenarios are considered in this study: 1) conventional pellets (CP), 2) modestly torrefied pellets (TP1) and severely torrefied pellets (TP2). TP1 has the lowest cost of $7.03 /GJ LHV at a moisture of 33 wt.% and a depot size of 84 MW LHV. The effects of climatic conditions and biomass field conditions were also studied for three scenarios. In humid regions of Michigan, TP2 is more economical than other scenarios because of the increased production of combustible gas. The three scenarios have similar sensitivities to biomass field conditions.

“…As for the particle sizes, it shows that the smaller particles, 0.5mm has higher moisture content when compared with the bigger particles, 1.5mm. This can be explained as the small wood particle size well absorbed water than the bigger particle size [17] and hence after subjected to oven dry still contain more amount of water than bigger particle size.…”

Currently, the primary energy supply in Malaysia is dominant by non-renewable energy sources such oil, natural gas and coal which contributed to the scarcity of these sources and occurrence of global warming. This phenomenon raises the public concerns to diversify the energy sources to sustain energy availability. To address these predicaments, biomass sources is among the prominent alternative energy sources since it is renewable and possesses minimal harms to the environment. Thus, the woody plant with high growth rate and high energy content that can be used to serve as potential biomass energy sources. In this study, small diameter (5-8cm) of wild Acacia mangium species have been determined and compared accordingly three (3) different portions (bottom, middle and top) and two (2) different particle sizes (0.5 and 1.5mm). The analysis conducted to determine the properties of raw material of Acacia mangium as biomass energy sources were proximate, physical and energy content properties. The result obtained for the energy content analysis of small diameter wild Acacia mangium has a mean calorific value range from 16.35 to 18.35MJ/kg between portions and particle sizes. In order to determine the effect of portions and particle sizes on each of the proximate, physical and energy content properties, two-way ANOVA was performed. It shows that both the portions and particle sizes have significant effect on calorific value (energy content) of small diameter wild Acacia mangium at 99% of confidence level. In a nutshell, the biomass energy properties of small diameter wild Acacia mangium with different portions and particle sizes were being determined.

“…Crushed carbonated SCG, BA, and KC, and scoured particles smaller than 175 μm (after mesh screening) were mixed in five different ratios, as shown in Table S1, so that the weight of each specimen was kg. A water and Ca(OH) 2 solution in a ratio of 20:1 was added to each mixture to represent 15 wt.% [37][38][39]. The solution was added and mixed for 10 min.…”

The development of biomass fuels to replace fossil fuels is on the rise, with increased bioenergy research on spent coffee grounds (SCG). However, no biofuel can currently replace anthracite briquettes. Unlike ordinary solid fossil fuels, anthracite briquettes are heated for a long time and retain the same form after combustion, making them easier to transport. In this study, binders are used to develop a solid fuel that allows SCG to retain their shape after combustion. Specifically, bottom ash (BA) and kaolinite clay (KC) are mixed in different ratios then processed with a press machine and cured to produce briquettes that exhibit zero damage, even after combustion. The results show that the optimal composition for SGC briquette production according to fuel quality and ash shape retention is 20 wt.% SCG; 71 wt.% BA; 9 wt.% KC; and 15 wt.% solution with a 20:1 water/Ca(OH) 2 mixing ratio. This results in a low heating value of 15.8 MJ/kg, 86.82% durability before combustion, and 99.46% durability after combustion. In addition, combustion tests with SCG briquettes confirmed their potential as an environmentally friendly alternative fuel to anthracite briquettes.
