“…It can also guarantee energy security and tackle environmental problems [3], and contributes to its efficient management and to developing rural areas economically [4]. The potential of using biomass wastes in producing high energy concentrated fuels in the form of briquettes has been explored by researchers [5][6][7]. Corncobs and oil palm trunk (OPT) are examples of biomass wastes of plant origin, and are readily available in Nigeria.…”

“…Briquetting can be done with a small amount of energy using low compaction pressure. Briquettes produced under a lower pressure technique have been reported to easily fall apart, while those under high pressure remained durable [41], However, a compaction pressure of ≤7 Mpa has been used to produce low cost briquettes that are durable [6,39,42]. These researchers used binding agents, which is a requirement for low pressure densification.…”

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.

“…High volatile matter results in easing ignition and enhancing combustion [32]. Conversely, high ash content decreases the heating value and increases the thermal resistance to heat transfer [32,[36][37][38]. The heating values of all ratios were found to be in the range of 19.57-20.17 MJ/kg, as shown in Fig.…”

“…The peak of mass loss rate of RT0:CT100 was more than those at RT100:CT0, RT75:CT25, RT50:CT50 and RT25:CT75. The second stage, the temperature range of 190-450°C, with a sharp peak at 260-275°C, and thermal increase of volatility as hemicellulose (190°C-320°C), cellulose (280°C-400•C), and lignin (320°C-450°C) lost content in carbonized briquettes [32]. The peak of mass loss in this stage rate of RT0:CT100 was more than those at RT100:CT0, RT75:CT25, RT50:CT50 and RT25:CT75.…”

“…As shown in Table 7, the physical properties of the carbonized briquettes, including volatile matter, ash content, and fixed carbon, were in the range of 27 to 37%, 14 to 33%, and 31 to 39%, respectively. High volatile matter results in easing ignition and enhancing combustion [32]. Conversely, high ash content decreases the heating value and increases the thermal resistance to heat transfer [32,[36][37][38].…”

The purpose of this research was to study the physical and economic characteristics of carbonized briquettes from rain tree (Samanea saman) residues and coffee ground/tea waste with cassava starch (10% wt.). This experiment utilized five treatments. As a binder, 10% wt. cassava starch was added to five ratios of rain tree residues to coffee ground/tea waste: RT100:CT0, RT75:CT25, RT50:CT50, RT25:CT75, and RT0:CT100. The physical properties of the carbonized briquettes were analyzed using ASTM methods. The results showed that carbonized briquettes made from 50% rain tree (Samanea saman) residues and 50% coffee ground/tea waste (RT50:CT50) had the highest calorific value (20.17 ± 0.042 MJ/kg)-insignificant at the 95% confidence interval-and highest shatter index (99.16 ± 0.20%). However, all ratios of rain tree residues to coffee ground/tea waste can produce carbonized briquettes for household use, convenient for transportation. In terms of economic performance, carbonized briquettes made from 50% rain tree (Samanea saman) residues and 50% coffee ground/tea waste (RT50:CT50) achieved the optimal payback period (approximately six months). Thus, making carbonized briquettes from rain tree residues and coffee ground/tea waste a viable alternative method of adding value to biomass residue for use as raw materials to produce fuel products for household cooking.

The current study took Henan Wufeng New Energy Science Technology Co. Ltd as an example to investigate a large‐scale steam heating system with biomass briquette fuel in Henan, China. Drawn on several months of field research, the economic cost and greenhouse gas emissions for peanut shell straw collection, transportation, storage and burning at Henan Wufeng New Energy Science Technology Co. Ltd were analyzed in 2021. Moreover, the economic cost and greenhouse gas emissions were used as evaluation indicators to evaluate the biomass molding fuel supply system systemically. Economic analysis shows that the steam heating system can make a profit of 1.72 × 106 yuan per year, and the input–output ratio (ROI) is 93.87%, which is much higher than the benchmark input–output ratio (30%). The very high ROI indicates that the system is difficult to operate in an economically feasible manner. Greenhouse gas emission analysis demonstrates that at the same heating level, the system can save 4.42 × 107 kg of standard coal and reduce the emissions of greenhouse gases to the environment by 1.25 × 105 tCO2eq, which has significant environmental benefits. Taken together, the government should adopt effective economic policies to promote the efficient use of biomass straw and support biomass straw recycling and heating enterprises. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
