“…The current results suggested that the briquettes produced without pongamia cake (S1) have had better stability than briquettes produced with pongamia cake (S2, S3, S4). In addition, compressed density, relaxed density and relaxation ratio values of briquettes obtained for S1 at 200 MPa were superior when compared to the respective parameter values obtained for sawdust briquettes and water lettuce briquettes reported [18,19]. Shattering index is a parameter which indicates the quality of briquette, i.e., the ability to produce fewer fines during handling.…”

“…Relaxation ratio is an important parameter to indentify the stability of the briquette. The increase in the relaxation ratio of the briquettes decreases the stability of the briquettes after ejection from the mould [18]. In figure 5, it is showed that as the percentage of binder (PC) was increased from 0 to 20% there were a consecutive increase in the relaxation ratio at all pressures.…”

Biomass is receiving greater attention, especially in developed countries, mostly as a means of reducing greenhouse gas emissions, increasing energy supply security and decreasing their heavy reliance on imported fossil fuels. However, the low bulk density of biomass is the major limitation in its usage but briquetting overcomes this limitation. This research was carried out to identify the optimum blending ratio for solid fuel briquettes produced by pongamia (Pongamia pinnata) shell (PS) and tamarind (Tamarindus indica) shell (TS) with pongamia cake (PC) (0, 10, 20, 30%) as an additive. The cylindrical briquettes were produced with diameter of 3.6 cm and length of 4.5 to 5.5 cm at a pressure of 100, 150 and 200 MPa. The produced briquettes were evaluated for different briquette properties like compressed density, relaxed density, relaxation ratio, compressive strength and shattering index. The results indicated that the use of pongamia cake creates an adverse effect on the properties of briquettes and hence use of pongamia cake as an additive is not recommended. Briquettes produced with blending ratio of PS:TS:PC = 60:40:00 at 200 MPa have better quality and met the briquette standards for commercial use. The proximate analysis, the ultimate analysis and the calorific value of briquettes produced with blending ratio of PS:TS:PC = 60:40:00 at 200 MPa were conducted and the results indicated that overall combustion properties of the briquettes were improved than the original raw materials; and better than the agro waste briquettes. Thus, this work proved that the blending of PS and TS gives better quality briquettes which can be used as fuel in several applications.

“…Other studies measured the relaxed density after the briquette reached a constant moisture constant following densification [30]. The density of biomass briquettes could be significantly influenced by a number of process variables, including moisture content, particle size, quantity of binder, compaction temperature, and pressure [11,92,147].…”

The adverse effect of the use of fossil fuels on the environment and public health has given rise to a sustained renewable energy research and development. An important component of global renewable energy mix is the use of loose biomass, including agricultural and forestry residues, to produce solid fuels in the form of briquettes. Briquettes play a significant role in bioenergy mix in developing and developed countries. The production of biomass briquettes often entails the collection, transportation, storage, processing, and compaction of loose biomass that meet specific quality parameters. The densification process often involves the addition of binders to improve the cohesive strength of the briquette material. This paper surveys recent literature from 2012 to 2021 to establish the current state of research on the use of binders in briquette production; and reviews current parameters used in assessing the quality of biomass briquettes with focus on mechanical and handling properties. While a number of quality parameters were identified, their assessment methodologies varied widely in the literature, thus necessitating standardization for comparability purposes. The review also includes factors affecting the wide production and adoption of biomass briquettes in most developing economies and proposes ways of overcoming the bottlenecks.

Physical and thermal properties of briquettes produced by recycling charcoal dust under different processing conditions have been reported in this study. The main aim was to investigate the effects of the binder and processing conditions on the properties of briquettes. The effect of adding molasses binder on combustion properties of the briquette was first assessed. Then by fitting experimental data, mathematical models to predict gross calorific value, ash content, moisture content, relaxed density and shatter index with respect to binder mass fraction, drying temperature and compaction pressure were developed. All briquettes properties were predominantly affected by amount of molasses used. Molasses mass fraction increment in briquette results in significant increment in ash content, moisture content, relaxed density and shatter index and significant reduction in gross calorific value. Drying temperature did not have major influence on briquette properties except moisture content. Compaction pressure (50-150 MPa) used in this study had negligible influences on all briquette properties. Therefore, such high pressure which involves energy consumption is not necessary during production of charcoal dust briquettes. Optimized values of gross calorific value and shatter index were 29.031 MJ/kg and 80.363%, respectively, for 50 MPa compaction pressure, 29.512 °C drying temperature and 10% molasses mass ratio.
