“…coccinea (18.50%) > sawdust (13.01%) > lemongrass (7.69%) > cashew leaves (5.69%). The FC content for corncob is in trend with the findings of Onokwai et al, Akogun and Waheed, Anukam et al, and Ibeto et al For sawdust, the FC contents reported by Varma et al and Mensah et al were 12.68 and 13.33 ± 0.8%, respectively, which tallies with the result obtained in this study (13.01%). However, previous studies reported higher FC percentages for lemongrass (24.78%) and cashew leaves (16.87%) .…”

“…Biomass is the most copious source of energy on earth, including plants, animals, waste, and by-products of both plants and animals. Many countries are increasingly interested in the use of various biomass as raw materials to produce energy . According to a report from IEA (2021), biofuels provide approximately 3% of the world’s fuel for transportation and are projected to meet 12% of worldwide transportation fuel demand by 2030.…”

There is a lack of information about the detailed characterization of biomass of Nigerian origin. This study presents a comprehensive characterization of six biomass, groundnut shells, corncob, cashew leaves, Ixora coccinea (flame of the woods), sawdust, and lemongrass, to aid appropriate selection for bio-oil production. The proximate, ultimate, calorific value and compositional analyses were carried out following the American Standard for Testing and Materials (ASTM) standards. Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy with energy-dispersive X-ray spectroscopy, and Xray fluorescence were employed in this study for functional group analyses, thermal stability, and structural analyses. The H/C and O/C atomic ratios, fuel ratio, ignitability index, and combustibility index of the biomass samples were evaluated. Groundnut shells, cashew leaves, and lemongrass were identified as promising feedstocks for bio-oil production based on their calorific values (>20 MJ/kg). Sawdust exhibited favorable characteristics for bio-oil production as indicated by its higher volatile matter (79.28%), low ash content (1.53%), low moisture content (6.18%), and high fixed carbon content (13.01%). Also, all samples showed favorable ignition and flammability properties. The low nitrogen (<0.12%) and sulfur (<0.04%) contents in the samples make them environmentally benign fuels as a lower percentage of NO x and SO x will be released during the production of the bio-oil. These results are contributions to the advancement of a sustainable and efficient carbon-neutral energy mix, promoting biomass resource utilization for the generation of energy.

“…The high volatile matter would make the fuel smoky with a lot of pollutants during combustion. The higher volatile matter can be reduced significantly by carbonization (Ibeto, 2016). The volatile matter of bagasse briquette (Clay as a binder 20:80) and bagasse briquette (molasses as a binder 10:90) obtained from this study is 27 and 25%, respectively and less than the briquettes produced from rice husk which was 67.98 (Oladeji, 2010).…”

Large quantities of bagasse are regularly accumulated on open spaces around sugar factory thereby endangering fragile ecosystem. The sugar cane bagasse carbonization process can be put into effect as an environmentally friendly, energy self-providing continuous flow technology. Therefore, the objective of this study was to use bagasse for the production of high caloric value briquette to safeguard the environment from pollution. Bagasse sample was collected from Wonje sugar factory and carbonized in an oxygen deficient environment at Ethiopian Rural Energy Development and Dissemination Center Laboratory, Addis Ababa. The carbonized materials were mixed with clay and molasses as a binder in different ratio to make a briquette using briquette extruder machine. Caloric value of the briquettes produced from bagasse using clay and molasses as a binder in different ratio ranged between 3,529-4,064 and 3,964-4,442 cal/g, respectively. The highest caloric value using clay as a binder was in the ratio 20:80 and the lowest caloric value using molasses as a binder was in the ration 25:75. Further analysis showed that through conversion of bagasse from Wonji sugar factory into briquette, annually the factory could generate 3.1×10-10 cal of energy and substitutes 13.01 m 3 of firewood or save 0.13 to 0.16 ha of tropical forests from deforestation and have the potential to sequestrate 17.90 to 22.03 tons of carbon annually. Further, the study concluded that briquettes produced from bagasse could be used as a quality source of energy and bagasse waste management option around sugar industry.

“…Meanwhile, several studies have been carried out on fuel enhancement potential of the pre-treatment of biomass and other lignocellulosic materials (Ibeto et al 2017 ; Sher et al 2020 ; Chaves et al 2021 ). Torrefaction, which is the thermal and chemical transformation of materials at the temperature of 200 to 300 °C in an inert atmosphere, has been used extensively to transform bioresource from agricultural waste to biocoal (Basu, 2018 ; Mamvura and Danha, 2020 ; Ong et al 2021 ; Yek et al 2021 ).…”

In recent years, the need for clean, viable and sustainable source of alternative fuel is on the rampage in the global space due to the challenges posed by human factors including fossil induced emissions, fuel shortage and its ever-rising prices. These challenges are the major reason to utilize alternative source of energy such as lignocellulosic biomass as domestic and industrial feedstock. However, biomass in their raw form is problematic for application, hence, a dire need for torrefaction pre-treatment is required. The torrefaction option could ameliorate biomass limitations such as low heating value, high volatile matter, low bulk density, hygroscopic and combustion behaviour, low energy density and its fibrous nature. The torrefied product in powder form could cause air pollution and make utilization, handling, transportation, and storage challenging, hence, densification into product of higher density briquettes. This paper therefore provides an overview on the performance of torrefied briquettes from agricultural wastes. The review discusses biomass and their constituents, torrefaction pre-treatment, briquetting of torrefied biomass, the parameters influencing the quality, behaviour and applications of torrefied briquettes, and way forward in the briquetting sector in the developing world.
