“…Such optimization would render biochar commercialization on a large scale with multiple benefits such as soil health improvement, yield increase, GHG reduction, and climate change mitigation. Although a variety of recent reviews (Kavitha et al, 2018;El-Naggar et al, 2019;Sakhiya et al, 2020;Bolan et al, 2022;Abhishek et al, 2022;Amalina et al, 2022;Uday et al, 2022) have presented potential benefits of biochar applications across different fields. However, synthesis and current knowledge on biochar-soil-plant interactions is direly needed to elucidate the soil and plant responses to different biochars by considering the type of feedstock, pyrolysis temperature, and biochar application and management practices under different environmental conditions.…”

Biochars provide several agricultural and environmental benefits, such as soil health improvement, better crop growth and yield, carbon sequestration, decreasing greenhouse gas (GHGs) emissions, and regulation of nutrient dynamics. This review highlights the role of biochar in transforming the soil’s physiochemical and biological properties, and their impact on improving seed germination and seedling growth, altering crop physiological attributes, enhancing crop resistance against biotic and abiotic stresses, improving crop productivity, curtailing GHGs, and controlling nutrient leaching losses. However, the type of feedstock used, pyrolysis temperature, application rate and method, soil type and crop species largely influence the biochar performance under different environmental conditions. Application of biochars at low rates help to promote seed germination and seedling growth. Biochar modified the abiotic and microbial processes in the rhizosphere and increased nutrient mineralization and enhanced the nutrient availability for plant uptake. Hence, biochar enhanced the plant resistance against diseases, reduced the availability of heavy metals and improved the plant resilience against environmental stressors. By providing a comprehensive analysis about the variable impacts of biochars on soil physicochemical properties, plant growth, development and productivity and mitigating environmental problems, this review is quite valuable for developing an efficient soil and crop specific biochar with desired functionalities. It could be helpful in improving crop productivity, ensuring food security and better management of environment. Furthermore, this review identifies the knowledge gaps and suggests future outlooks for the commercialization of biochar applications on large-scale.

Antibiotic contamination in water bodies poses ecological risks to aquatic organisms and humans and is a global environmental issue. Persulfate-based advanced oxidation processes (PS-AOPs) are efficient for the removal of antibiotics. Sustainable biochar materials have emerged as potential candidates as persulfates (Peroxymonosulfate (PMS) and Peroxydisulfate (PDS)) activation catalysts to degrade antibiotics. In this review, the feasibility of pristine biochar and modified biochar (non-metal heteroatom-doped biochar and metal-loaded biochar) for the removal of antibiotics in PS-AOPs is evaluated through a critical analysis of recent research. The removal performances of biochar materials, the underlying mechanisms, and active sites involved in the reactions are studied. Lastly, sustainability considerations for future biochar research, including Sustainable Development Goals, technical feasibility, toxicity assessment, economic and life cycle assessment, are discussed to promote the large-scale application of biochar/PS technology. This is in line with the global trends in ensuring sustainable production.

Agricultural waste reduction was significant for the novel pathways of "waste control by control" and "synergize the reduction of pollution and carbon emissions". This study explores the utilization of crop waste through the preparation of sawdust biochar (SBC) via high-temperature pyrolysis for the adsorption removal of the neonicotinoid insecticide nitenpyram (NTP). A comprehensive characterization of SBC's physicochemical properties was conducted using various techniques such as scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, Brunauer−Emmett−Teller analysis, Fourier-transform infrared spectroscopy, thermogravimetric analysis, Raman spectroscopy, zeta potential analysis, and X-ray photoelectron spectroscopy. The sample subjected to pyrolysis at 900 °C with a particle size range of 75−150 μm (BC900M) exhibited an organized porous structure with a high specific surface area of 682.7 m 2 /g and an abundance of surface active groups and oxygencontaining functional groups. At optimal conditions (NTP concentration = 150 mg/L and BC900M dosage = 0.3 g/L), BC900M demonstrated a notable adsorption capacity of 115 mg/g. The NTP adsorption behavior aligned with the Langmuir and Freundlich isotherm models (R 2 > 0.96), the pseudo-second-order kinetics model, ΔH = 40.04 kJ•mol −1 and ΔS = 0.219 kJ•K −1 •mol −1 , indicating a spontaneous and endothermic physical process involving both monolayer and multimolecular adsorption. The mechanisms encompassed micropore trapping, hydrogen-bond interactions, electrostatic attraction, π−π interactions, halogen bonding, and coordination interaction. Furthermore, a positive correlation between the adsorption performance of biochar and the pyrolysis temperature was observed, which was attributed to the decreased degree of graphitization of SBC based on the I D /I G ratios of BC300, BC500, BC700, and BC900 of 0.96, 1.01, 1.06, and 1.11, respectively. The adsorption free energy between NTP and SBC was −8.05, −8.31, −8.61, and −9.23 eV for BC300, BC500, BC700, and BC900, respectively. Those findings provide important insights for the efficient utilization of biomass resources for organic pollutant removal via high-performing adsorbents.
