In this work, a combined multi-analytical and multivariate framework is developed to elucidate how waste-derived precursor type, pyrolysis temperature, and iron functionalization collectively control adsorption and heterogeneous Fenton-like oxidation in biochar-based systems. Biochars were produced from 4 waste-derived precursors: spent coffee grounds, olive pomace, olive pomace stones, and sewage sludge, at three pyrolysis temperatures (450, 550, and 650 °C), generating 12 pristine materials and, after iron functionalization, a total of 24 materials. This design enables a systematic evaluation of waste-to-resource pathways and the decoupling of compositional and structural effects. Advanced characterization was combined with I-optimal response surface methodology (RSM) and principal component analysis (PCA) to provide complementary information: RSM was used to optimize material and process variables, whereas PCA was applied to interpret structure-property-performance relationships and identify the main descriptors controlling adsorption and heterogeneous Fenton-like oxidation. Equilibrium adsorption data were better described by the Freundlich model (R<ce:sup loc=\"post\">2</ce:sup> ≥ 0.97), indicating that surface heterogeneity was a dominant factor, while Langmuir-derived Qmax values were used only as comparative capacity indicators. Lignocellulosic biochars were governed by surface area and aromaticity, whereas sewage-sludge-derived biochars showed enhanced affinity due to their mineral-rich matrices and oxygenated functionalities. Iron functionalization significantly improved performance, with Fe-SSBC450 showing the highest Langmuir-derived adsorption capacity (Qmax = 6.57 mg g<ce:sup loc=\"post\">−1</ce:sup>) and oxidation efficiency (∼76% phenol removal). Oxidation proceeded via <ce:sup loc=\"pre\">•</ce:sup>OH-driven mechanisms following pseudo-second-order kinetics. This work demonstrates how waste-derived precursors can be valorised into high-value materials for environmental remediation, supporting circular economy strategies through resource-efficient water purification.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"38 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148852380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polyacrylamide grafted coconut shell biochar (PAM-BC) was synthesized via in situ polymerization to overcome previous limitations. PAM-BC exhibited effective adsorption performance in aqueous solutions, with maximum capacities reaching 151.3 mg/g for Cd²⁺ and 174.1 mg/g for Pb²⁺. In a soil-plant system, PAM-BC significantly decreased bioavailable fractions of Cd²⁺ and Pb²⁺ by 56.1%/76.1%, respectively. The reduction effectively inhibited migration and accumulation of heavy metals in plant roots, stems, as well as leaves. Concurrently, the microbial community was optimized through the enrichment of beneficial functional bacteria as well as the suppression of harmful populations. The remediation performance is attributed to the unique architecture. A three dimensional network was constructed by the extension of flexible PAM chains into rigid pores, and the biochar skeleton was preserved. Abundant -NH₂ and -COOH groups facilitated stable chelation with Cd²⁺ and Pb²⁺, achieving dual enhancement via physical entrapment as well as chemical fixation.

This study investigated the effects of PGPB and their co-inoculation with the AMF <em>Rhizophagus clarus</em> on grain yield, plant nutrition, and microorganisms associated with common bean roots. The experiment was conducted in a randomized block design with an 8 x 2 factorial scheme and four replicates, and was repeated in the same plots over two winter cropping seasons. The treatments consisted of inoculation with the PGPBs <em>Azospirillum brasilense, Azomonas macrocytogenes, Azotobacter beijerinckii, Bacillus amyloliquefaciens, Bacillus aryabhattai, Burkholderia vietnamiensis, Nitrospirillum amazonense</em>, and an uninoculated control, combined or not with <em>R. clarus</em>. The results demonstrated that co-inoculation efficacy is highly context- and strain-dependent. significant increases in grain yield were achieved when <em>R. clarus</em> was applied alone. Furthermore, true synergistic increments were observed under co-inoculation with <em>Bur. vietnamiensis</em>, <em>Az. brasilense</em>, or <em>Azot. beijerinckii</em>. Significant grain biofortification was observed, with specific PGPBs enhancing nitrogen and magnesium export, while the AMF increased iron export. Conversely, the incompatibility of certain co-inoculations was evidenced by antagonistic effects, such as the reduction in yield following the co-inoculation of <em>R. clarus</em> + <em>A. macrocytogenes</em>. Finally, the analysis of the root-associated microbiome - restricted to a subset of three selected PGPB strains and their co-inoculations with <em>R. clarus</em> (<em>Az. brasilense, Bur. vietnamiensis,</em> and <em>N. amazonense</em>) - revealed that the inoculations did not alter the overall diversity but were observed in association with exclusive genera, driving specific qualitative changes in the microbial community without altering its global structure. In conclusion, under the conditions of this single cultivation site, this study demonstrates that <em>R. clarus</em> can benefit winter common bean by increasing yield and inducing qualitative changes in low-abundance root-associated taxa. Similarly, PGPB and their co-inoculations with AMF can benefit crop yield and nutrition, depending on the specific microbial combination.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"574 ","pages":"Article 149118"},"PeriodicalIF":10.7,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148692958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we conducted a global meta-analysis using 6489 paired observations from 107 studies to quantify how biochar addition affects plant biomass, biomass partitioning, plant functional traits, and soil properties across terrestrial ecosystems. Biochar addition increased overall plant biomass accumulation by 40.1%, with significant gains in whole-plant biomass, aboveground biomass, and belowground biomass of 35.4%, 36.6%, and 48.0%, respectively. The root-to-shoot ratio also increased by 16.0%, showing that biochar addition promoted growth while shifting biomass allocation. Plant functional types showed contrasting responses to biochar addition. Herbaceous plants exhibited significant increases in total, aboveground, and belowground biomass together with a higher root-to-shoot ratio, whereas woody plants showed biomass increases but relatively stable allocation patterns. Biochar addition was also associated with improvements in soil physicochemical and biological properties, enhanced root morphology and physiology, promoted stem and leaf development, and increased photosynthetic capacity. Meta-regression further showed that biomass responses increased with mean annual temperature, mean annual precipitation, biochar pH, biochar total carbon content, and initial soil organic carbon. In contrast, application rate, experimental duration, and biochar specific surface area and initial soil pH showed nonlinear, moderator-specific responses. Our analysis further showed that repeated biochar applications were associated with substantially stronger biomass responses than single applications. These effects reveal biochar sensitivity to management and background environmental conditions. Overall, our findings demonstrate that biochar influences multiple dimensions of plant and soil functioning and highlight its important role in regulating plant productivity and soil processes across environmental conditions.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"574 ","pages":"Article 149127"},"PeriodicalIF":10.7,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148692975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper, for the first time, proposes a novel “virtual expert” framework to capture the spatiotemporal heterogeneity of marine environments for data-driven suitability assessment of global OFPV potential. Under current-stage assumptions, our analysis reveals that within Exclusive Economic Zones, stringent techno-environmental constraints curtail the initial 14,831,550 TWh/year (128.94 million km²) theoretical potential by 93.7%. This yields a realizable potential of 935,110 TWh/year across 9.04 million km², underscoring the profound impact of technical and environmental thresholds on OFPV expansion. Regionally, Asia dominates in absolute potential, while Africa boasts the highest average suitability, with specific cyclone-exempt African nations achieving 100% “most suitable” coverage as promising early-stage deployment candidates. Constraint analysis identifies water depth as the primary physical barrier, eliminating vast high-radiance areas across Europe, the Americas, and Africa. Meanwhile, sea ice and marine protected areas impose absolute exclusions in high-latitude and ecological hotspots, whereas low-latitude deployments—notably in Asia and Oceania—demand robust tropical cyclone resilience. Furthermore, spatially resolved techno-economic assessments reveal that while unconstrained marine areas achieve an average levelized cost of energy of 9.16 US cents/kWh under standardized economic assumptions, some constrained zones nevertheless retain relatively favorable solar economics, suggesting that deep-water station-keeping and cyclone-resilient floating structures may become high-priority R&amp;D directions for future OFPV innovation. Ultimately, these findings demonstrate that OFPV deployment is inherently a highly localized spatial optimization challenge, our framework providing a macro-siting tool to assist stakeholders in balancing clean energy expansion with marine conservation and environmental risk mitigation.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"574 ","pages":"Article 149126"},"PeriodicalIF":10.7,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148693090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CO₂ adsorption tests combined with the Avrami model were employed to quantitatively evaluate the CO₂ capture capacity, while FTIR confirmed the coupling of physical adsorption and chemical carbonation processes.
