“…Biochar as a soil conditioner has become a global focus due to its potential for yield improvement, carbon sequestration, soil remediation, and climate change mitigation (Al‐Wabel et al, 2018; Diatta et al, 2020; Purakayastha et al, 2019; Woolf et al, 2010). Moreover, biochar can be obtained from the pyrolysis of solid waste (e.g., crop, wood, and animal waste), which could contribute to sustainable production systems and economic and environmental benefits (Cao et al, 2022; Ghorbani et al, 2023; Qambrani et al, 2017). Owing to its special properties, biochar applied to soil can significantly influence soil physicochemical properties, including reducing bulk density, increasing carbon sequestration, and improving hydrological characteristics and soil aggregation conditions (Alghamdi, 2018; Liang et al, 2021; Zhang et al, 2021).…”

Biochar, an environmentally friendly soil amendment, has the potential to alleviate soil degradation. However, the mechanisms and effects of biochar addition on soil microbes and metabolic limitation in degraded soils are still ambiguous because of the complex ecosystem and the varying conditions of planting. Therefore, a field experiment with six biochar application rates (0, 24, 60, 96, 132, and 168 Mg ha−1, applied in the 0–20 cm soil layer) was conducted in a loessial soil without planting to determine the response of metabolic limitation and the microbial community to the biochar application rate. Soil samples were collected in mid‐May and mid‐August (before and during the rainy season). The results showed that the soil microbial metabolic activity without biochar application was phosphorus (P) limited in mid‐May (vector angle = 81.37 ± 0.31°) and nitrogen (N) limited in mid‐August (vector angle = 27.36 ± 1.54°), and nutrient limitations generally decreased in the biochar treatments. Structural equation modeling indicated that microbial metabolic restriction was mainly influenced by biochar‐induced changes in element stoichiometric ratios and available phosphorus (p < 0.05). Under the influence of biochar content, only the carbon (C) limitation influenced bacterial composition by directly or indirectly affecting dissolved organic carbon and NO3−–N. However, the fungal composition was strongly shaped by both C limitation and P/N limitation. Our results indicated that the soil P status and its stoichiometric ratios play an important role in the biochar effects on metabolic limitation and that bacteria and fungi have different compositional responses to metabolic limitation in loessial soil.

“…The precursors of HC always come from a wide range of sources, including animal biomass, [16] plant biomass, [17] organic polymers, [18] resins, [19] etc. Among them, resins and organic compounds perform better than biological ones, but considering the cost and sustainability, plant-based materials are more suitable to be used as precursors derived carbon anode of SIBs.…”

The increasing demand for sodium‐ion batteries has risen due to sodium resources that are inexpensive and abundant compared with its counterpart of lithium‐ion batteries. Development of anode materials with high performance is central issue for sodium‐ion batteries. Plant‐based hard carbon material is a promising anode material for sodium ion batteries due to its green preparation process, favorable ions transport channel, and special porous structure. Previous studies have not systematically correlated the material's inherent structure limitation with its electrochemical properties, resulting in a complex classification and a lack selection of pretreatment methods. In this review, the intrinsic limitations in the structure of plant‐based precursors are divided into four parts, including impure components, single chemical structure, uncontrollable crystalline texture, and irregular porous structure. The previous pretreatment methods are reclassified, including purification component aiming at plant‐based precursors, optimized structure, and precabornized process aiming at intermediate products. Furthermore, the pretreatment strategies are discussed according to the preferred structures of plant‐based hard carbon and the relationship between structure and performance is systematically expounded. This review provides deep understanding of the mechanism of pretreatment and a guide for selecting appropriate pretreatment strategies to optimize the structure of plant‐based hard carbon for sodium ion batteries.

“…Following citrus and bananas, pineapple is the third most popular fruit worldwide. , The Food and Agriculture Organization of the United Nations (FAO) reports that in 2019, pineapples were cultivated on 1.125 million hectares with a yield of 28.179 million t worldwide. Both freshly consumed and processed pineapples produce vast amounts of the crown, stem, peel, and trimmings, which typically make up 50–60% (w/w) of the total weight of the pineapple. − If these wastes are not adequately managed, they may pollute the environment through leachate generation, landfill gas emissions, and the development and release of air pollutants such as dioxins, furans, acid gases, and particulate matter through incineration. − The state of the ecosystem will directly threaten both human and animal health . After cellulose, hemicellulose, and lignin, the bioactive chemical polyphenols are the fourth significant component of pineapple peel waste and are a potential source of functional food components, natural antibacterial agents, and antioxidants …”

Plant polyphenols' antibacterial capabilities are just beginning to be applied in the environment. In this study, solvent recovery and concentration techniques were used to achieve zero-waste extraction of pineapple peel polyphenol (PPP) powder on an industrial scale. For environmental sterilization, PPP antibacterial agents (PAAs) were created. Their physicochemical and antibacterial qualities were examined, and technical and financial analysis was done. The results showed that (1) among the major PPP components, protocatechuic acid content was the highest (48.90 mg/L), followed by quercetin dihydrate (17.56 mg/L); (2) PAA sprays passed the tests for physicochemical properties like pH and heat resistance; (3) at the 8 mg/mL concentration, PAA achieved 100% bacterial inhibition below 40 °C; and (4) the production cost of 8 mg/mL PAA spray was only $273.41/t at 100,000 t industrial scale. These findings might offer an application prospect in the development of renewable bacteriocins from fruit and vegetable waste materials.
