Abstract Due to large specific surface area, abundant functional groups and low cost, biochar is widely used for pollutant removal. The adsorption performance of related synthesis parameters. But the influence factor numerous, traditional experimental enumeration powerless. In recent years, machine learning has been gradually employed biochar, but there no comprehensive review on whole process regulation adsorbents, covering optimization modeling. This article systematically summarized application in adsorbents from perspective all-round first time, including modeling adsorbents. Firstly, overview was introduced. Then, latest advances removal were summarized, prediction yield physicochemical properties, optimal synthetic conditions economic cost. And by reviewed, efficiency, revelation mechanism. General guidelines whole-process presented. Finally, existing problems future perspectives put forward. We hope that this can promote integration thus light up industrialization biochar. Graphical

Abstract We synthesized 20 years of research to explain the interrelated processes that determine soil and plant responses biochar. The properties biochar its effects within agricultural ecosystems largely depend on feedstock pyrolysis conditions. describe three stages reactions in soil: dissolution (1–3 weeks); reactive surface development (1–6 months); aging (beyond 6 months). As ages, it is incorporated into aggregates, protecting carbon promoting stabilization rhizodeposits microbial products. Biochar persists for hundreds thousands years. By increasing pH, porosity, water availability, biochars can create favorable conditions root functions. Biochars catalyze biotic abiotic reactions, particularly rhizosphere, increase nutrient supply uptake by plants, reduce phytotoxins, stimulate development, resilience disease environmental stressors. Meta‐analyses found that, average, P availability a factor 4.6; decrease tissue concentration heavy metals 17%–39%; build organic through negative priming 3.8% (range −21% +20%); non‐CO 2 greenhouse gas emissions from 12%–50%. show average crop yield increases 10%–42% with addition, greatest low‐nutrient P‐sorbing acidic soils (common tropics), sandy drylands due retention holding capacity. Studies report wide range diversity contexts which have been applied. Crop yields strongly if site‐specific constraints limitations are mitigated appropriate formulations. be tailored address site selection, modifying conditions, pre‐ or post‐production treatments, co‐application mineral fertilizers. demonstrate how, when used wisely, mitigates climate change supports food security circular economy.

Abstract Heavy metals and metalloids can accumulate in soil, with potentially toxic effects to human health ecosystems, threatening the sustainable use management of soil resources. Although a number remediation technologies, such as Solidification/Stabilization (S/S), washing, electrokinetic chemical oxidation/reduction be applied for immobilization, removal or detoxification heavy environmental, social economic impacts associated these conventional approaches hinder their overall sustainability. More attempts have been made maximize ‘net environmental benefit’ various ways, including recovering resources, embracing nature‐based solutions (NBS), saving energy emergence development ‘green remediation’ (GSR) movement. This review critically discusses green strategies, novel amendments being utilized approaches. Iron‐based are most promising candidates due highest stabilization performances both oxyanions metallic cations well relatively low disturbance soil. In comparison, waste‐derived materials suffer from risks contaminant release long run, reducing sustainability despite costs. It has found that phytoremediation amendment‐based S/S typically ‘greenest’ but wise decisions should on basis case‐specific assessment results. Finally, it is proposed integration several techniques may synergistic effect efficiency.

Numerous harmful chemicals are introduced every year in the environment through anthropogenic and geological activities raising global concerns of their ecotoxicological effects decontamination strategies. Biochar technology has been recognized as an important pillar for recycling biomass, contributing to carbon capture bioenergy industries, remediation contaminated soil, sediments water. This paper aims critically review application potential biochar with a special focus on synergistic antagonistic contaminant-degrading microorganisms single mixed-contaminated systems. Owing high specific surface area, porous structure, compatible chemistry, can support proliferation activity microorganisms. A combination remove variety contaminants gained popularity recent years alongside traditional chemical physical technologies. The microbial compatibility be improved by optimizing parameters so that toxic pollutant release is minimized, biofilm formation encouraged, populations enhanced. Biocompatible thus shows bioremediation organic harboring populations, releasing enzymes, protecting beneficial from immediate toxicity surrounding contaminants. recommends biochar-microorganism co-deployment holds great removal thereby reducing risk human environmental health.

Abstract Carbon neutrality by the mid-twenty-first century is a grand challenge requiring technological innovations. Biochar, traditional soil amendment which has been used for fertility improvement and contaminant remediation, revealed new vitality in this context. In review we highlight huge potential of biochar application different fields to mitigate as high 2.56 × 10 9 t CO 2 e total greenhouse gas (GHG) emissions per year, accounting 5.0% global GHG emissions. Soil applications either controlled-release fertilizer or an immobilization agent offer improved health while simultaneously suppressing CH 4 N O. Non-soil also contribute carbon unique ways. Firstly, ruminant feed decreases via physical sorption enhanced activities methanotrophs. Secondly, can be green catalyst biorefinery. Besides, additive Portland cement low impact development (LID) infrastructure lowers footprint builds resilience climate change. Furthermore, novel batteries supercapacitors energy storage purposes. Finally, adsorption capacity makes it possible being sorbent capture, utilization, (CCUS). We advocate that future research should further explore effectiveness systems change mitigation large scale applications, assess economic social viability local combat Graphical
