“…Isto indica que os pós de partida durante a sua compactação estão sendo reduzidos. O principal responsável pelo aumento dos valores de densidade compactada foi a pressão através de sua ação simultânea na redução do tamanho dos pós e poros onde eles foram inseridos [13,14,15]. ABSTRACT: Electric energy was the driving force behind the development of industrialization and is fundamental for the current expansion of sectors.…”

“…High pressure and temperature application affect the binding mechanism of wood briquettes by forming strong bonds between particles and increasing particle contact, or by reducing the distance between particles, resulting in dense and high-density wood briquettes [60]. According to Križan et al [61], the density of wood briquettes will increase if the pressure is increased. The compaction pressure affects the formation of bonds between the pressed wood particles.…”

The development and utilization of wood briquettes is one of the efforts to reduce dependence on fossil fuels, including to fulfill overseas market need. This study aimed to evaluate the properties of wood briquettes made of the branches of three mangrove species and to analyze the effect of different wood species of mangrove branches, and the types of starch adhesive, on the quality of wood briquettes. The wood briquettes made in this study were 3 cm × 4 cm in a cylindrical shape using three wood species of mangrove branches, namely mata buaya (Bruguiera sexangula), buta-buta (Excoecaria agallocha), and bakau minyak (Rhizophora apiculata), while the adhesives used were tapioca starch, maize starch, and potato starch. The results showed that the moisture, ash content, and calorific value of the wood briquettes mostly met the ISO 17225-3:2-2020 class A2 standard and the specification and quality standards of wood briquettes for Grade A2 issued by the Korea Forest Research Institute, except the density. Wood briquettes made of mata buaya by using the three types of starch adhesives generally had better properties than all other types of wood briquettes. The interaction of mangrove wood species and the types of starch adhesive had a significant effect on the properties of wood briquettes, except for volatile matter and calorific value for which they had no significant effect. The use of wood briquettes from mangrove wood branches contributes to sustainable forest management and maintains the ecological function of mangrove forests while providing environmentally friendly alternative energy for households as a source of fuel/energy. Furthermore, future research is needed, such as investigating the optimal pressing pressure needed to achieve higher density of the wood briquettes.

“…A proper amount of moisture in the feedstock is as an important factor in the pelletizing process, whereas excessive moisture contents weaken hydrogen bonds and van der Waals forces, due to increasing the distance between particles [109]. In earlier studies, the optimal moisture that could be used in the compaction process of biomass was reported to be within 7.8-15% [110]. Fresh raw materials generally require a lower moisture content (around 7-8%), whereas stored materials require approximately 11-13% [111,112].…”

The development and utilization of biomass can not only address the demand for low-carbon energy and reduce environmental pollution, but can also facilitate the achievement of carbon neutrality. However, there are many factors justifying the case for low utilization of agricultural residues. These factors could be well controlled by producing top-quality pellets. Production of pellets is generally accompanied by the problems of high energy consumption and serious mold wearing. To eliminate these deficiencies, pretreatment has attracted scholars’ attention. In this review, the effects of four pretreatments on the properties of pellets were assessed. Thermal pretreatment can improve the hydrophobicity of pellets, and optimize their properties, while degradation of diverse extractives is noteworthy. Hydrothermal pretreatment improves the physical properties of pellets, through the increase of polar functional groups on the surface of the biomass. Ultrasonic vibration-assisted (UV-A) pelleting produces pellets under low pressure without a heating process; however, it is still not applied to large-scale production. Supercritical fluid extraction can achieve the graded utilization of extracts and bioactive substances in biomass, and the residues can be subsequently utilized as pellet feedstock. Mild hydrothermal treatment is a promising approach to improving the quality of agricultural pellets. Additionally, the effects of process parameters on the physical and chemical properties of pellets should be systematically analyzed.
