“…In relation to food waste as the feedstock, biochar will be produced upon hydrocarbons’ emission during the reaction. Though, Amalina et al [ 7 ] reported that the combustion process is unfavorable for the biochar synthesis as it converts most of the carbon in biomass to CO 2 . Typically, combustion in a boiler produces about 1.5–2.0% of biochar [ 17 ].…”

“…Hence, the supply requires a huge increment to meet the demand, while the development of materials ought to exhibit high electrochemical performance, inexpensive, and easy to be scaled up at an industrial level. Furthermore, the electrode materials are the vital components in the electrochemical performance testing, as it determines the energy storage systems’ performance [ 6 , 7 ]. The parameters that are often studied and reported in the EES application are gravimetric specific capacitance (F/g), energy density (Wh/kg), power density (W/kg), and cycle stability, though some literatures have also been reported in a volumetric scale, i.e., Wh/L and W/L.…”

The abundance of food waste across the globe has called for the mitigation and reduction of these discarded wastes. Herein, the potential of biochar derived from food waste is unquestionable as it provides a sustainable way of utilizing the abundance of available biomass, as well as an effective way of preserving the ecosystem through the reduction of concerning environmental issues. This review focuses on the food waste–based biochar as advanced electrode materials in the energy storage devices. Efforts have been made to present and discuss the current exploration of the food waste utilization, along with the biochar production technologies through thermochemical conversion, including combustion, gasification, and pyrolysis method. Finding its limitation in literatures, discussion on the food waste–based biochar fabrication method as the electrode materials is elaborated, alongside the current food waste–based biochar that has been explored in the energy application thus far. Towards the end, the outlook and perspective on the further development of food waste–based biochar have been outlined.

“…As mentioned in other research, biochar has a high carbon content, a densely packed pore structure, a large specific surface area, and stable physicochemical characteristics. [58][59][60] Therefore, it can be applied to sequester carbon, adsorb heavy metals, adsorb organic matter, and protect the environment. [61][62][63]…”

“…Generally, pyrolysis is divided into three kinds based on the rate of temperature rise: flash pyrolysis, fast pyrolysis, and slow pyrolysis (Table 2). [58,59] Then products are transformed into three phases: solids (coke), liquids (bio-oil), and fuel gas, as depicted in Figure 4.…”

Chinese medicine is widely employed in illness prevention and treatment. In recent years, the increased demand for Chinese medicine resources has resulted in a large quantity of waste created during industrialization. However, traditional methods for treating herbal residues, including burning, stacking, and burying, can cause significant environmental damage and resource waste. Furthermore, these application approaches have a low level of resource utilization and a low degree of utilization. Therefore, developing a classification management system is a necessary precondition for reusing Chinese herb residues for medicinal, feed, fertilizer, and energy resource reuse. This paper reviews the potential applications of Chinese herb residues in the extraction of active resources, composting, feed addition, bioethanol preparation, and pyrolysis to biochar, bio‐oil, and fuel gas. Overall, this work provides a foundation for further investigation into the high‐value usage model and resource reuse pathway of Chinese herb residues.

Huge amounts of vegetable waste, mainly resulting from the food industry, need large areas for storage, as they could cause hazardous environmental impact, leading to soil and water pollution or to CO2 emissions during accidental incineration. This work was aimed at recycling certain lignocellulosic waste (walnut shells, kernels of peach, apricot, and olive) to design advanced carbon material precursors (ACMP) to be used for obtaining nano-powders with high applicative potential in pollution abatement. Both waste and ACMP were characterized using proximate and elemental analysis, and by optical microscopy. Complex characterization of raw materials by FTIR, TGA-DTG, and SEM analysis were carried out. The ACMP were synthetized at 600–700 °C by innovative microwave heating technology which offers the advantages of lower energy consumption using 3.3 kW equipment at laboratory level. The ACMP ash < 3% and increased carbon content of 87% enabled the development of an extended pore network depending on degassing conditions during heating. TEM analysis revealed a well-developed porous structure of the synthesized ACMP carbonaceous materials. Due to the presence of oxygen functional groups, ACMPs exhibit adsorption properties highlighted by an iodine index of max. 500 mg/g and surface area BET of 300 m2/g, which make them attractive for removal of environmental pollutants such as dyes having molecule sizes below 2 nm and ions with pore dimensions below 1 nm, widely used industrially and found in underground waters (NO3−) or waste waters (SO4−2).
