“…The use of AC has been researched extensively and as the surface area and pore volume of the AC increases, its use in heavy metal removal increases in tandem. Basaleh et al were able to remove 94% of lead (Pb) ions from an aqueous solution at optimum conditions when using AC. Chen et al used biochar derived from food digestate to remove lead and cadmium with maximum removal of 355.3 and 217.4 mg.g -1 , respectively .…”

BACKGROUND: Brewer's Spent Grain (BSG), a form of lignocellulosic biomass more commonly known as barley waste was used to synthesize activated carbon (AC) and carbon nanotubes (CNTs). The produced materials were used in water remediation application. RESULTS:A novel approach involving two activation steps; first, with phosphoric acid (designated BAC-P) and then using potassium hydroxide (designated BAC-K) was proposed for the production of AC and CNTs from BSG. The AC produced showed a surface area as high as 692.3 m 2 g −1 with a pore volume of 0.44 cm 3 g −1 . This can help aid and facilitate the circular economy by effectively upcycling and valorizing waste lignocellulosic biomass to high surface area AC and subsequently, multi-walled carbon nanotubes (MWCNTs). Consequently, MWCNTs were prepared from the produced AC by mixing it with the nitrogen (N)-based material melamine and iron precursor, iron (III) oxalate hexahydrate, where it produced hydrophilic MWCNTs. Both AC and CNT materials were used in heavy metal removal (HMR), where the maximum lead absorption was observed for sample BAC-K with 77% removal capacity after the first hour of testing.CONCLUSION: This result signifies that the synthesis of these upcycled materials can have an application in the areas of wastewater treatment or other AC/CNT end uses with a rapid cycle time.

“…Recycling it can, on the one hand, reduce the pressure of urban solid waste disposal and ease the situation of garbage siege; on the other hand, it can realize the reuse of resources and promote sustainable improvement. In addition, some organic wastes contain toxic and harmful components, which can easily cause environmental pollution if improperly disposed of [6][7]. Organic solid waste can be divided into three categories: agricultural sources, living sources and other sources according to their sources.…”

Pyrolysis technology can convert organic solid waste into gas, liquid and solid three-state products, providing a variety of high-value utilization methods. High oxygen content and component complexity limit the high-value utilization of organic solid waste pyrolysis oil, and conventional catalysts will be deactivated due to carbon deposition during the catalytic upgrading of pyrolysis oil. The good fluidity and heat and mass transfer properties of the alkali metal molten salt can increase the effective contact area between the alkali metal cation and the reactant, and improve the reaction rate. At the same time, the alkali metal cation has a catalytic effect and can alleviate carbon deposition. The purpose of this paper is to analyze the potential of organic solid waste energy and clean utilization based on pyrolysis technology. In the experiment, salt catalytic heat treatment technology is used to convert organic solid waste pyrolysis oil model compound molten salt heat. The experimental results show that the introduction of molten salt reduces gas production and realizes clean energy.

“…2 Nevertheless, to date, most of the existing studies have been limited to using activated carbon synthesized from a single feedstock. 3 Kaghazchi et al 4 reported that current practices are undesirable because each of the carbonaceous feedstock has its own limitations. Hence, modification of the characteristics of activated carbon (through the combination of precursors) is encouraged to synthesize porous carbon with plentiful advantages.…”

BACKGROUND: Over the years, activated carbon has been widely used for environmental applications, including liquid or gas phase applications. However, there are many hurdles for researchers in the activated carbon field to overcome when it comes to non-renewable materials, the utilization of individual precursors, and the complex multistep procedures of activated carbon synthesis. Therefore, in this study, the facile mechanochemical potassium carbonate (K 2 CO 3 ) activation of blended precursors palm kernel shell and petroleum cokewas investigated in terms of the activated carbon yield and carbon dioxide (CO 2 ) adsorption capacity. RESULTS:The optimum configuration of the activated carbon production was found at temperature of 680°C, holding time of 60 min, and impregnation ratio of 1.75:1. The CO 2 adsorption data at 25-120°C was best represented by the Sips model with R 2 > 0.9999, where maximum CO 2 adsorption capacity (q max ) was within the range of 2.24-4.32 mmol/g. The kinetic analysis was well-represented by the pseudo-second order model due to the high R 2 and low sum of square of errors (ERRSQ) value. In terms of thermodynamic analysis, it showed that the CO 2 adsorption process was physical, exothermic, and spontaneous at lower temperature. CONCLUSION: Overall, the integration of agricultural and industrial waste to value-added activated carbon was feasible not only in reducing waste disposal problems but also in facilitating CO 2 mitigation.
