“…The scale chart was used to find the color of biofuel by ASTM D1524. In addition, the properties of biofuel may vary due to its processing, temperature, infiltration process, processing, reactor type, capacity of reactor, and catalyst (Isaac Premkumar et al., 2020; Sanchez et al., 2022). The evaluated biofuel properties are tabulated in Exhibit 5 and compared with pre‐defined diesel properties.…”

“…Biofuel retained from the source of agricultural biomass is the future energy reported by Timbers and Downing (1977). The pyrolysis technique is best for biofuel extraction from agricultural waste (biomass) (Sanchez et al., 2022). The above literature related to waste vegetable recycling through the production of Bio‐energy with various techniques was discussed, and found research gap on pyrolysis changes the fuel quality for high‐temperature processes.…”

The impact of growth in the overall population is imposed on the continuous degradation process for environmental wastes like agricultural, industrial, food products, farming waste, etc. The improper degradation may lead to pollution and toxicity for ecological living. Based on waste management concepts, environmental wastes are reduced, reused, and recycled against environmental pollution. Most environmental wastes are recycled and used as biofuel for various energy sectors like alternative fuels. Globally, vegetable loss or wastage increased by more than 35% due to the level of retailers and consumers. The present study attempts to produce a low‐cost, reliable, environmentally emission‐free biofuel using waste vegetable resources via pyrolysis reactor arrangements. The synthesized bio‐fuel energy implemented for compression ignition engine and its performance was evaluated by single cylinder four stroke diesel engine and found higher brake power and thermal efficiency of 6.89 kW and 50.29%. Finally, the emission characteristics are assessed by an exhaust gas emission tester. CO and HC emissions showed minimum amounts like 0.021% and 47 ppm.

Background Ethiopia’s energy relies mainly on biomass sources, residues of crops and animal dung collections. Over 90% of domestic energy needs in Ethiopia are met by biomass, which contributes to deforestation and climate change. This study investigates the usage of water hyacinth and country’s largely produced agricultural waste (groundnut shells) for the production of briquettes using potato peels as a binder. Methods Water hyacinth, groundnut shells, and potato peel waste were used for production of briquettes. Briquettes were prepared using three parameters; temperature (350 ℃, 450 ℃ and 550 ℃), particle size (0.5, 1 and 1.5mm) and mixing ratio (25%, 50% and 75%). Physical properties and calorific values for the developed briquettes were determined using FTIR machine and bomb calorimeter. Central composite design by the design expert was used to design the experiment, and response surface methodology was used to optimize the calorific value of the produced briquettes. Statistical analysis tool such as analysis of variance was employed to show whether the process variables were statistically significant on the response variable (P < 0.05). Results The developed briquettes had the highest calorific value, 25.52 MJ/kg. The maximum bulk density and durability of the produced briquettes were 0.553% and 97.86%, respectively. The moisture content, volatile matter, ash content, and fixed carbon content of water hyacinth biomass were 8.14%, 68.49%, 10.3% and 13.06%, respectively. The moisture content, volatile matter, ash content, and fixed carbon of the groundnut shells were 9.2%, 66.84%, 3.615% and 20.34%, respectively. The produced briquettes had a moisture content ranging from 8.470–11.760%, and ash content ranging from 5.850–8.750%. Temperature, particle size and mixing ratio were statistically significant on the calorific value of the briquettes (p < 0.05). The optimised briquettes have a calorific value of 24.544 MJ/kg, at a temperature, particle size and mixing ratio of 453.380℃, 0.999 mm, and 50%, respectively. Conclusion The produced briquettes had good calorific value, bulk density and durability, and were suitable for cooking and heating purposes. This revealed that agricultural wastes could be used to augment the energy sources pool to protect the environment and create social stability in the community.

“…It is needed to enhance ecosystems and increase comfort for humanity. There are several sources of energy that could serve as a preferable replacement for nonrenewable energy sources, such as coal and other fossil fuels [1,2]. Biomass as a veritable source of energy is gaining research interest in both developing and developed countries [3,4].…”

Energy used for domestic application is expensive and utilization of an alternative energy has become imperative. The study evaluated the combustion properties of briquettes produced from sawdust particles of Ficus exasperata and Cassava peel using different binders. Sawdust was mixed with the binders at a ratio (60 : 40) top bond, (40 : 60) starch and (60 : 40) cow dung, while the cassava peel mixed with the binders at a ratio (40:60) top bond, (60 : 40) starch and (40 : 60) cattle dung. This is followed by admixture of sawdust and cassava peel with the binders at ratio (25 : 25 : 50) top bond, (25 : 25 : 50) sawdust and (25 : 25 : 50) cattle dung, and substrate mixed with binders at ratio (20 : 20 : 20 : 20 : 20) respectively. Data analysis was carried out using a two-way analysis of variance. The proximate composition result reveals that the percentage ash content was significant at p<0.05. Results on binders revealed that heating value (HV) was highest at starch (32.48Mj/kg) and lowest in cattle dung (30.9Mj/kg) while result on substrate reveals highest HV at sawdust (32.79Mj/kg) and lowest in cassava peel (30.39) with significant higher % ash content (9.5). Therefore, this study reveals that briquette of admixture of sawdust and cassava peel bonded with starch had the best burning characteristics and could be maximized as alternative source to energy.
