“…For low moisture biomass, rising temperatures can harden the briquettes and make them denser [61]. In biomass briquettes produced under high temperatures (150-250 • C), there is also an increase in the properties of calorific value, volatile matter, density, water-resistance and relaxation rate of solid fuel [16,62].…”

The densification of raw material into fuel briquettes is one of the routes to convert biomass into energy. This method provides uniformity to the solid fuel, better physical and energy properties, facilitating its storage and transport, in addition to more homogeneous combustion. Given the importance of these characteristics, this work presents a literature review, emphasizing the experimental levels of the variables of the briquetting process, as well as on the most relevant quality parameters for obtaining briquettes. We also carry out a survey of the main technologies used in the production of briquettes, as well as the experimental methodologies and statistical analysis used in the planning and validation of processes. It was observed among the studies that the raw material granulometry, followed by pressure, initial moisture, compaction time and binder are the most used process variables for the production of briquettes. Other factors, such as the proportion of biomass, process temperature and thermal pre-treatments are used to obtain greater energetic and physical responses. Among the works, divergences were observed regarding the relevance and interaction of some process variables on the quality variables of the briquettes, indicating the need for the experiments to be mathematically modeled.

“…Problems related to the disposal of agricultural and industrial biomass wastes can in part be addressed through their use as biomass fuel, in forms like briquettes . If produced at low cost and made conveniently accessible to consumers, biomass briquettes can serve as complements to firewood, charcoal, and kerosene for domestic cooking and agroindustrial operations, thereby reducing the high demand for other fuels . Briquettes have many advantages over conventional firewood, including higher heat content, ease of use, cleanliness, and compact size.…”

Effectively utilizing agro residues, when abundantly available, can help energy conservation efforts and increase farmers’ incomes. This article highlights the effective utilization of agro and industrial biomass residues in the form of briquettes. The various types of feedstock used and the technologies adopted in the briquetting process are discussed. Process parameters and feedstock variables influencing briquetting are described. Combustion studies undertaken using briquettes are comprehensively detailed. This literature review reveals that the combustion characteristics of briquettes not only depend on the type of the feedstock but also on the density, moisture content, binder percentage, and method used for briquetting. Higher ash content lowers the calorific value. The ash formed during combustion causes slagging and fouling which in turn lead to corrosion. It is concluded that biomass briquettes can meet the energy demands for cooking and heating needs, especially in rural areas where abundant biomass feedstock is available. It is recommended that research focuses more on investigating emissions along with the combustion of briquettes manufactured from different origins.

Efficient utilization of biomass requires conversion into forms that can be optimally applied in energy generation. Briquetting involves compaction of biomass into solid blocks that are more efficient than raw biomass and provides for ease of transport and handling. These are improved when the briquettes possess high shatter index and compressive strength. Due to difference in nature and composition, it is imperative to define optimum conditions for the production of quality and durable briquettes for individual biomass compacted into briquettes. This study studied the effects of process variables on the strength and durability of biomass briquettes produced using Abura sawdust. The lateral compressive strength and drop shatter index were investigated whilst varying the temperature (100-150 °C), pressure (9-15 MPa) and hold time (15-30 min). The compressive strength ranged between 2.06 and 5.15 MPa whilst the shatter index was between 50 and 600. The pressure was significant to the determination of the compressive strength (p &lt; 0.1) and the shatter index (p &lt; 0.05). Mechanical characteristics of the binderless Abura sawdust briquettes can be improved by optimizing the densification variables during the briquetting process when moderate pressures are used for compaction.
