“…The obtained bulk density is higher than the values reported in the literature, which may vary due to the moisture content of the biomass, the variety of corncob, and the fractional composition. Ibitoye et al [53] relate changes in density to particle size and suggest that density increases with decreasing particle size.…”

“…The literature lacks specificity regarding the moisture content and the physico-mechanical properties of the compacted corncob raw material. Ibitoye et al [53] evaluated briquettes of rice husk and corncob blends dried for 3 days (100:0, 80:20, 70:30, 60:40, and 50:50). It was found that density increases with increasing compaction force and rice husk content in the blend and with decreasing particle size; durability increases with finer particle size and is directly related to compaction pressure; and fracture and impact resistance decreases with increasing corncob fraction and particle size [53].…”

However, it is very difficult to judge because the moisture content of the compacted raw material, for both rice husk and corncob, is not clear.…”

Due to environmental pollution and global warming, the use of renewable energy sources such as agricultural residues is gaining attention. Corn is the main source of food in many countries, and after harvesting it, the agricultural and industrial sectors generate significant amounts of residues. This study focused on corncob processing, its preparation, and the evaluation of its characteristics for energy needs. There was no significant difference between drying with active ventilation in the dryer and outdoor drying conditions. The adequate moisture content of corncob pellets is 12.39% at a compression ratio of 3.43 ± 0.011 and a maximum pellet density of 1012.96 ± 3.35 kg m−3. The variation in pellet density at a given adequate moisture content is at least 0.78%. The compression ratio of the pellets compacted on the horizontal matrix granulator is 9.75% higher than that of the pellets produced on the laboratory automatic press. The corncob’s lower calorific value was 17.35 ± 0.14 MJ kg−1, and the ash content was 1.78 ± 0.24%. The produced pellets are strong enough and can be used for combustion. This research may help to better understand the properties of corncobs and their energy potential.
