“…Additionally, new thermal processing technologies might make biomass pellet production more profitable [32][33][34]. Research efforts should also focus on identifying suitable raw materials for use as additives in pellet production, as not all biomass materials are appropriate for this purpose [35][36][37].…”

This paper presents research findings on the pelleting process of pine sawdust using bakery waste in a pelletizer. The addition of bakery waste (white wheat–rye bread, whole-grain rye bread, and pumpkin bread) to pine sawdust had a beneficial effect on the kinetic strength of the pellets obtained, an increase of up to approximately three percentage points. The density of pellets with the addition of bakery waste also increased, while the bulk density of the pellets decreased. The addition of bakery waste also had a positive effect on the power demand of the pelletizer. It was reduced from 3.08% (at a 10% addition of white wheat–rye bread) to 22.18% (at a 20% addition of pumpkin bread), compared to the process of compacting pure pine sawdust. In addition, all the pellets containing bakery waste had a lower energy yield (EY) determined based on lower heating value and energy inputs. This index was lower by 53 Wh·kg−1 for pine sawdust pellets with a 10% addition of pumpkin bread. The greatest reduction, on the other hand, was by 173 Wh·kg−1 for pellets, with a 20% addition of white wheat–rye bread. In each case, an increase in the share of bakery additives resulted in a decrease in the energy yield from the pellets obtained. The smallest reduction in EY was found when pumpkin bread was used as an additive (from 53 to 133 Wh·kg−1). Considering all the parameters analyzed characterizing the pellets obtained, it was concluded that the addition of bakery residues to pelletized pine sawdust should not exceed 10%. Further increases in the proportion of bakery waste did not yield relative benefits, due to the deterioration of the energy characteristics of the pellets obtained.

“…The difference in structural results for NB and SB pellets might be due to the presence of organic and inorganic constituent's in sugar cane trash which causes SB to form compact and strong pellets while for NB pellets binder failed to form strong bonding with particles. As literature suggested that wood residue [40] and bagasse [16] pellets show better results for NB (LGBRB) instead of SB (LSBSB). In SB pellets a different type of bonding mechanism was identi ed due to the formation of lignin bridge and mechanical interlocking [41].…”

The growing demand of energy and the concurrent uplift in greenhouse gas emissions is attributed to the global waning of fossil fuels. In this regard, densification of biomass presents a viable and eco-friendly approach for producing solid fuels. Sugarcane trash is one of the promising biomasses used for energy production. This study aims to analyze and evaluate the effect of pretreatment and binder’s concentration on the densification of sugarcane trash. For this purpose, sugarcane trash is pretreated with hot water at 80°C in a 1:15 solid-to-liquid ratio (S/L) and densified by adding two different starch-based binders named as natural binder (low-grade broken rice) (NB) and synthetic binder (Maya) (SB) with three different concentrations i.e., 10%, 20% and 30%, followed with the palletization. After densification, the pellets are characterized by physical, mechanical, thermal, and structural properties. The results indicated that pellets with 10%SB presented optimum properties. Pellets with 10%SB pellets showed higher heating values (4301.17 Cal/g) (HHV), a crucial property for the design calculations or simulations of thermal conversion for biomass. The pellet strength is suggested to be linked with the composition of binder and biomass which is linked with the binding of binder and biomass material in the densified biomass. It is evident from the results that sugarcane trash pellets can fulfill energy requirements as per the needs of the present era keeping in view the green and sustainable environment. Thus, rather than burning the sugarcane trash which causes pollution, densified pellets are of great significance for bioenergy production.
