“…Recent studies have demonstrated that biocarbon can be a renewable alternative to carbon black, which is widely used in the industry as a colorant and filler in automotive parts and rubber products [ 11 , 12 ]. Biocarbon is a promising option for entrapping carbon, and provides numerous opportunities for use in a variety of sectors, notably in soil amendment, catalyst, energy storage devices, and polymer composites [ 13 , 14 , 15 , 16 ]. It is a versatile material because it can be chemically modified.…”

Miscanthus biocarbon (MB), a renewable resource-based, carbon-rich material, was melt-processed with poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) to produce sustainable biocomposites. The addition of the biocarbon improved the Young’s modulus of PHBV from 3.6 to 5.2 GPa at 30 wt % filler loading. An increase in flexural modulus, up to 48%, was also observed. On the other hand, the strength, elongation-at-break and impact strength decreased. Morphological study of the impact-fractured surfaces showed weak interaction at the interface and the existence of voids and agglomerates, especially with high filler contents. The thermal stability of the PHBV/MB composites was slightly reduced compared with the neat PHBV. The biocarbon particles were not found to have a nucleating effect on the polymer. The degradation of PHBV and the formation of unstable imperfect crystals were revealed by differential scanning calorimetry (DSC) analysis. Higher filler contents resulted in reduced crystallinity, indicating more pronounced effect on polymer chain mobility restriction. With the addition of 30 wt % biocarbon, the heat deflection temperature (HDT) became 13 degrees higher and the coefficient of linear thermal expansion (CLTE) decreased from 100.6 to 75.6 μm/(m·°C), desired improvement for practical applications.

“…Given that both types of capacitors are very costly to make, thus making the need for the less expensive ones indeed an urgency. At present, activated carbon (AC) derived from biomass materials such as corncobs [13], enteromorpha [14], hemp [15], infested ash trees [16], loofah sponges [17], melons [18], olive pits [19], pinecones [20], peanut shell [21], rice husk [22], starch [23], shiitake mushrooms [24], tobacco waste [25], and willow catkins [26], have been employed as carbon precursors for fabricating electrode materials for supercapacitors due to their abundance, renewability, low-cost and environment friendly properties. In previous studies [27,28], addition of multi-walled carbon nanotubes (MWCNT) to commercially available activated carbon increased the energy density and specific capacitance of supercapacitor cells.…”

An electric double-layer capacitor (EDLC) was fabricated using multi-walled carbon nanotubes (MWCNT) and activated carbon (AC) derived from Moringa Oleifera fruit shells as electrode material. The carbonization temperature and the weight ratio of the fruit shells to the activating agent were varied to determine the best condition in the fabrication of the electrodes. Activation of the carbonized fruit shells by ZnCl 2 resulted in the formation of pores as verified by the scanning electron micrographs. Energy dispersive X-ray analyses show that the washing of the carbonized sample resulted in the removal of zinc and chlorine residues. The supercapacitor electrodes were fabricated by adding polyvinylidene fluoride and N-methylpyrrolidone to the MWCNT-AC mixture to form a slurry and was cast onto a nickel foam. The capacitance of the fabricated electrodes was determined using a potentiostat. The activated carbon with a carbonization temperature of 800 C and a 1:2 weight ratio between the fruit shells and ZnCl 2 was observed to have the highest capacitance of 130 F g À1 and was duplicated to fabricate the supercapacitor electrodes. A glass microfiber filter was soaked in 3 M KOH and placed in between the two electrodes. The specific capacitance of the EDLC was found to be 122 F g À1 at a current density of 0.5 A g À1 , average energy density of 17 W h kg À1 , average power density of 1.5 kW kg À1 and an equivalent series resistance of 1.6 Ω. After 100 scans with a scan rate of 0.1 V s À1 , the percent decrease in capacitance was calculated to be 2.65 % of its original capacitance.

“…As a result, the use of biochar from biomass has emerged as a cheap and easily accessible carbon source for SC electrodes [122]. Research on opportunity of using SC carbon material obtained from pyrolysis of biomass (ash wood) as an electrode material has been carried out by Canadian team [123]. They observed that the presence of non-electrified areas with the possibility of the availability of electricity only from renewable (solar, wind) or combustion generators.…”

This review comprehensively examines biochar, an essential material in an era of climate change for reducing carbon dioxide (CO2) emissions into the atmosphere. It is inconspicuous, black, lightweight, and very porous, and is produced through the thermal conversion of biomass. Our literature review highlights biochar’s expansive application possibilities. Firstly, its potential to improve soil quality and sequester CO2 has been examined, as well as its utilization in iron and steel manufacturing to minimize the quantity of coke and ultimately reduce CO2 emissions. In industrial manufacturing, the complete elimination of coke can promote environmental neutrality, which is achieved using biochar from biomass for its extrusion. Furthermore, biochar is becoming increasingly significant in modern energy storage technologies and as an important additive in Pickering emulsions, which are also employed in energy storage systems. Additionally, the use of carbon black is a broad topic, and this review illustrates where it can be successfully utilized, especially in environmentally sensitive areas.
