This study presents a novel internal curing strategy using activated coconut biochar (10%–30%) and hemp fiber (10–30 mm) to simultaneously address shrinkage and strength deficits. Experimental findings demonstrate that mix-sized biochar improves both the fresh and hardened properties of the concrete when compared to using small or large biochar particles alone. Notably, while the incorporation of biochar reduces fluidity due to water absorption and increased inter-particle friction, both flexural and compressive strengths were enhanced – by up to 34% and 28%, respectively – with increasing biochar content and fiber length, as a result of matrix densification and fiber-bridging effects. The synergy between biochar and hemp fibers facilitates internal curing by lowering the local water–cement ratio during hardening and promoting cement hydration through both internal curing and nucleation effects. Despite a rapid early-stage increase in drying shrinkage, the combined addition of biochar and hemp fiber ultimately achieves a remarkable reduction of up to 96%. Furthermore, increasing biochar dosage and fiber length enhances matrix compactness, substantially reducing water absorption. This, in turn, improves resistance to chloride penetration by obstructing ion transport pathways. Concrete modified with 30% biochar and 30 mm-long hemp fibers demonstrates significant potential for carbon emission reduction, achieving decreases of 4.4 kg CO₂ eq./m³/MPa in compressive scenario and 23.8 kg CO₂ eq./m³/MPa in flexural scenario. Overall, this study advances the understanding of shrinkage mitigation mechanisms and offers a scalable pathway for the development of high-performance, low-carbon recycled aggregate concrete.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"22 ","pages":"Article 100265"},"PeriodicalIF":7.8,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145019722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ESGOnt addresses key challenges in sustainable resource governance systems and cross-sector interoperability by providing a unified structure for ESG and SDG integration. The framework was developed through a systematic methodology that combines a literature review, standardization of ESG and SDG relationships, development of an adaptable maturity model, and ontology implementation using established methods such as Methontology and NeOn. ESGOnt enables the integration of diverse ESG taxonomies and ESG reporting standards, including GRI and ESRS, and assists companies in their ESG performance evaluation. Empirical validation through real-world use cases demonstrates its capability to (1) direct assessment of ESG assessments with specific SDG targets, such as SDG13 (Climate Action) and SDG 12 (Responsible Consumption and Production), (2) assess organizational ESG progress through different metrics, (3) facilitation of standardized and interoperable reporting for small and large enterprises, and (4) automatically validate organization compliance with EU Non-Financial Reporting Directive regulations. The findings show that ESGOnt resolves data inconsistency and transparency issues by enabling integrated and auditable sustainability reporting. The ontology-driven approach of the framework enables scalable and policy-relevant tools for tracking environmental and social impacts, while its maturity model focuses on strategic improvements in resource efficiency. Future studies will analyze and extend ESGOnt’s functionality for sector-specific capabilities, such as bioeconomy control systems, and explore advanced AI-driven inspection methods for real-time ESG-SDG assessment.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"22 ","pages":"Article 100262"},"PeriodicalIF":7.8,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144907662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In accordance with the GHG Protocol Corporate Standard (Scope 1, 2 &amp; 3), the LCA system for camellia oil spans from the nursery gate to the oil-mill gate, covering all direct (Scope 1), indirect energy (Scope 2) and upstream value-chain (Scope 3) greenhouse gas (GHG) emissions (assessed with global warming potential, GWP) associated with both forest farm operations and oil mill processes.

Traditional CH₄ mitigation strategies, such as mechanical aeration, sediment capping, and vegetation management, face challenges related to high costs, inefficiency in oxygen delivery, and ecological disturbances. In recent years, interfacial oxygen nanobubbles (IONBs) have emerged as a promising geoengineering solution for reducing CH₄ emissions by providing sustained oxygenation in anoxic sediments. Unlike conventional methods, IONBs exhibit high stability, prolonged oxygen retention, and slow, controlled oxygen release, reducing the need for frequent re-application. This sustained oxygenation creates long-lasting aerobic microenvironments that suppress methanogenesis while stimulating methanotrophic CH₄ oxidation. Furthermore, IONB-loaded carriers, such as biochars and zeolites, enable targeted oxygenation, improving redox conditions and promoting beneficial microbial shifts. Compared to mechanical aeration, which rapidly dissipates oxygen, or chemical amendments requiring repeated treatments, IONBs provide a low-maintenance, cost-effective alternative with minimal ecological disruption. This review explores the physicochemical properties of IONBs, their mechanisms of action in altering sedimentary biogeochemical processes, and their potential applications in mitigating CH₄ flux from different aquatic ecosystems. Despite their potential, challenges remain in optimizing oxygen-loading capacity, assessing long-term ecological impacts, and scaling up production. Future research should focus on refining the oxygen-loading capacity of IONBs, integrating them with existing mitigation approaches, and evaluating their role in global climate policies. As an innovative and sustainable tool, IONBs hold great promise for advancing wetland conservation, reducing agricultural CH₄ emissions, and climate change mitigation efforts.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"22 ","pages":"Article 100256"},"PeriodicalIF":7.8,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144827511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

California sought to address both priorities simultaneously through Senate Bill (SB) 1383, a novel organic waste law. This article contributes to the literature on food loss and waste (FLW) mitigation by examining tensions between SB 1383’s dual goals: diverting organic waste from landfills and redistributing surplus food to communities in need. While SB 1383 is a progressive policy, its implementation has revealed conflicts between these objectives. We assess the impact of SB 1383 on stakeholder compliance with its food waste reduction and recovery requirements. Specifically, we examine the two key objectives of this regulation: (1) mitigating climate change by diverting organic waste from landfills, and (2) addressing food insecurity by redistributing recovered food to communities in need. We interviewed 37 stakeholders, including food recovery organizations, jurisdiction representatives, and edible food generators involved in implementation. Additionally, we analyzed the distribution of Local Assistance Grant funds across California counties and between the policy’s dual goals. Our findings indicate a stronger focus on waste diversion than food recovery, and an uneven distribution of funding, with rural areas facing greater challenges in adapting to SB 1383’s requirements.
