“…Table 3 and Figure 5 shows that the values for compressive strength of briquettes ranged from 10.26 to 22.33 MPa and are significantly different (p < 0.05) as assessed by ANOVA (Table 4). The hybrid briquettes displayed better compressive strengths than those of briquettes made from agro-based materials [85], pine needles [86] and banana tree waste [67]. The CC briquette displayed the greatest variation, while the OPTB, MIX 2 and MIX 3 briquettes exhibited higher compressive strengths in similar manner with their reported density values.…”

The objective of this research was to investigate the quality of hybrid briquettes developed from corncobs (CC) and oil palm trunk bark (OPTB) under a low-pressure densification technique. The materials were combined in varying ratios of CC to OPTB (100:0, 75:25, 50:50, 25:75, 0:100) and wastepaper pulp (10% by weight) was added to each mixture as a binder. The briquettes were produced using a manually operated 20-tonne hydraulic piston press at 28 °C temperature and ≤7 MPa compaction pressure. The mechanical strength of the briquettes was determined by the drop test and compression test methods, while a bomb calorimeter was used to determine the calorific values. The results showed that the physical properties of hybrid briquettes ranged from 9.24–10.00% moisture content, 0.38–0.40 g/cm3 density, and 87.60%–92.00% water resistance. Mechanical strength showed a 98.28%–99.08% shatter index and 18.47–21.75 MPa compressive strength, while calorific values ranged from 16.54–16.91 MJ/kg. The hybrid briquettes fared better than the CC briquettes. The significance of this study lies in the production of briquettes with suitable physical, mechanical and thermal properties by utilizing OPTB which have hitherto not been used, mixed with corncobs. This could bring substantial environmental and socio-economic benefits to rural communities of the developing countries.

“…Briquettes with a mixing ratio of 60:40 for Pongamia Shell (PS): Tamarind Shell (TS) under 200 MPa had better quality and met charcoal briquette standards for commercial use, in addition with the overall combustion properties of the briquettes were enhanced compared to the original raw materials. Deshannavar et al (2018) found that using carbonized rice husk with starch and bentonite clay as binders increased each of the briquette bulk density and the compressive strength by increasing the percentage of binder in the mixture up to 6% and then, they decreased with a further increase in binder concentration. Ajimotokan et al (2019) produced the briquettes using a pressure of 5 MPa for 5 min in a hydraulic briquette machine.…”

The aim of the present study is to produce high-quality charcoal briquettes from biomass residues. Experiments were conducted under conditions of three different biomass residues (rice straw, cotton stems and corn stalks), two binder materials (starch and carton paper) under two different concentrations (5 and 7 wt %) and four operating pressures (0.5, 1.0, 1.5 and 2.0 MPa). The produced charcoal briquettes were evaluated from physical, chemical, thermal and mechanical properties. The charcoal briquettes quality was evaluated and compared with original form of raw biomass residues.Results clarified that high-quality charcoal briquettes could be obtained from cotton residues by operating the press machine under pressure of 1.5 MPa at starch binder material with a concentration of 7 wt%. The previous conditions achieve appropriate charcoal briquette of 400 kg/m 3 bulk density, 85.23 % fixed carbon, 6.10 % volatile matter, 4.05 % ash content, 32.21 MJ/kg calorific value, 83.63 % thermal efficiency and 213.79 kg/cm 2 compressive strength.

“…Inevitable depletion of non-renewable and limited fossil fuel in the future, such as petroleum, coal, natural gas, etc., is an issue, since 80% of world’s energy generation was still dependent on the utilization of these fossil fuels [ 1 , 2 , 3 ]. The concern over this problem and advancing demand for energy with the increase of global human population and development of commercial and industrial activities, are raising awareness on the development of alternative energy source.…”

“…Lignin is reported to be used as a binder in briquette application [ 1 , 2 , 19 , 20 , 21 , 22 ]. Previous research studies utilized lignin as a binder for anthracite-based briquette [ 23 ], organic municipal solid waste [ 24 ], and wood [ 4 , 25 ].…”

Binderless, All-Lignin Briquette from Black Liquor Waste: Isolation, Purification, and Characterization

et al. 2021

Lignin isolated from black liquor waste was studied in this research to be utilized as binderless, all-lignin briquette, with a calorific value in the range of 5670–5876 kcal/kg. Isolation of lignin from black liquor was conducted using the acid precipitation method. Sulfuric acid, citric acid, and acetic acid were used to maintain the pH level, which varied from 5 to 2 for the precipitation process. The influence of these isolation conditions on the characteristic of lignin and the properties of the resulted briquette was evaluated through the Klasson method, proximate analysis, ultimate analysis, Fourier Transform Infrared (FTIR), adiabatic bomb calorimeter, density measurement, and Drop Shatter Index (DSI) testing. The finding showed that the lignin isolated using citric acid maintained to pH 3 resulted in briquette with 72% fixed carbon content, excellent 99.7% DSI, and a calorific value equivalent to coal-based briquette.
