A life cycle assessment (LCA) was conducted to evaluate the carbon footprint and resource efficiency of recycling straw waste into building materials. Three straw valorization pathways—straw resin-bonded particleboard (SRBP), straw cement-bonded particleboard (SCBP), and straw-based supplementary cementitious material (SCM)—were assessed and compared with the prevailing practice of straw open burning (SOB). Environmental and economic performance was evaluated in terms of greenhouse gas (GHG) emissions, global warming potential (GWP), non-renewable energy consumption, resource expenditure, and cost–carbon synergy indices. The assessment adopts a dual-dimensional framework, combining horizontal comparison among straw management scenarios with vertical benchmarking against conventional wood-based particleboards. Methodological novelty is further achieved by integrating a cost–carbon synergy index with a one-million-iteration Monte Carlo simulation to jointly quantify economic–environmental performance and uncertainty, and by grounding the analysis in region-specific industrial data from Jilin Province to support policy-relevant conclusions. Results show that SCM exhibits the lowest carbon footprint (273.18 kg CO2eq per ton of straw), whereas SOB produces the highest emissions (2834.80 kg CO2eq/t). Relative to conventional wood-based boards, SRBP and SCBP reduce GHG emissions by 9.90 % and 4.53 %, respectively, while lowering non-renewable energy demand by up to 3.08 % and 14.88 %. SCM achieves the largest emission mitigation potential, with a unit abatement cost of 0.072 CNY per kg CO2eq, substantially below representative social carbon cost thresholds, whereas SRBP and SCBP achieve positive cost–carbon synergy without direct fiscal support. Sensitivity analysis identifies transportation distance and molding electricity as dominant GWP drivers, and Monte Carlo simulation confirms the robustness of scenario ranking under parameter uncertainty. Overall, SRBP and SCBP offer economically viable pathways with synergistic emission reductions, while SCM provides substantial climate benefits through deep emission mitigation. These findings support targeted promotion of straw-based particleboards and the development of carbon-trading mechanisms for SCM, alongside logistics optimization and process-level emission reduction strategies.
采用生命周期评价方法（LCA）评价了秸秆废弃物资源化利用的碳足迹和资源效率。对秸秆树脂粘接刨花板（SRBP）、秸秆水泥粘接刨花板（SCBP）和秸秆基补充胶凝材料（SCM）三种秸秆增值途径进行了评估，并与秸秆露天焚烧（SOB）的普遍做法进行了比较。从温室气体（GHG）排放、全球变暖潜势（GWP）、不可再生能源消耗、资源支出和成本-碳协同指数等方面对环境和经济绩效进行了评价。该评估采用了双重框架，将秸秆管理方案的横向比较与传统木质刨花板的纵向基准相结合。通过将成本-碳协同指数与100万次蒙特卡罗模拟相结合，共同量化经济-环境绩效和不确定性，并以吉林省特定地区的工业数据为基础进行分析，以支持与政策相关的结论，进一步实现了方法上的新颖性。结果表明，SCM的碳足迹最低（每吨秸秆273.18 kg CO2eq），而SOB的碳排放量最高（2834.80 kg CO2eq/t）。与传统的人造板相比，SRBP和SCBP分别减少了9.90%和4.53%的温室气体排放，同时降低了3.08%和14.88%的不可再生能源需求。供应链管理实现了最大的减排潜力，单位减排成本为每千克二氧化碳当量0.072元人民币，大大低于代表性的社会碳成本阈值，而SRBP和SCBP在没有直接财政支持的情况下实现了积极的成本-碳协同效应。敏感性分析表明运输距离和成型电力是GWP的主要驱动因素，蒙特卡罗仿真验证了参数不确定性下情景排序的鲁棒性。总体而言，SRBP和SCBP提供了经济上可行的协同减排途径，而SCM通过深度减排提供了实质性的气候效益。这些发现支持有针对性地推广秸秆刨花板和发展供应链管理的碳交易机制，以及物流优化和过程级减排战略。

The United Nations' 2030 Agenda for Sustainable Development emphasizes conserving marine resources, making sustainable ocean economies a global priority. Coastal cities, critical hubs for marine-terrestrial systems, face dual pressures: driving growth and managing climate risks. This research examines how urban environmental resilience facilitates the sustainable marine economic development of coastal cities. Using data from 51 Chinese coastal cities spanning 2007 to 2022, the research constructs multidimensional indices for Marine Economy-Society Comprehensive Benefit Index and Environmental Resilience. To analyze the relationships, a two-way fixed-effects model is utilized. The analysis reveals that environmental resilience enhances the sustainable marine economic development, and with the mediating role of Foreign Direct Investment. Results demonstrate a nonlinear threshold effect: resilience significantly boosts sustainability in medium-resilience cities but yields diminishing returns in high-resilience regions. Regional heterogeneity is evident, with southern cities benefiting more due to export-oriented economies and disaster exposure, while northern cities face structural constraints. By integrating environmental and sustainable metrics, this research offers new insights into the resilience-sustainability linkages, enriches coastal studies with threshold and mediation frameworks, and provides actionable foundations for policymakers to tailor development strategies to local capacities.

This study investigates the performance and environmental impact of a 100% recycled EN 45500 aluminum alloy subjected to T6 heat treatment, using its primary counterpart as a benchmark. Both alloys were produced by gravity die casting under controlled laboratory conditions and subsequently characterized from a microstructural and mechanical standpoint. The recycled alloy exhibited a higher iron content, promoting the formation of Fe-based intermetallic compounds, which increased defect density and reduced ductility compared to the primary alloy. Heat treatment parameters were optimized to balance mechanical performance with energy efficiency. Tensile testing revealed that the recycled alloy achieved mechanical properties comparable to those of the peak-aged primary alloy when aged at 160 °C for 4.5 h, a less energy-intensive condition than the 180 °C for 4.5 h required by the primary alloy. The environmental impact analysis demonstrated a significant reduction in carbon footprint, from 19.6 kgCO2eq/kgAl for the primary alloy to 2.47 kgCO2eq/kgAl for the recycled one. For 100% recycled EN 45500 alloy, the heat treatment, including solution treatment and aging, accounted for 92.3% of CO2eq emissions, underscoring the relevance of heat treatment optimization. Overaging tests demonstrated that the recycled EN 45500 retained copper-driven thermal stability. Overall, the findings highlight the capability of recycled aluminum to meet both mechanical performance and sustainability requirements to produce advanced automotive applications.

Organic-waste treatment processes redistribute carbon, nitrogen, phosphorus, and sulfur across air, water, and soil, creating cross-media risks from uncontrolled losses that single-medium controls miss. However, elemental fluxes traverse multi-stage units with feedbacks and leakage, forming an interconnected, path-dependent network where amplification pathways and cross-media trade-offs remain unresolved. We develop an integrated three-module framework for synergistic pollution control of unintended CNPS releases. First, we cast the treatment system as a directed process network and model elemental flows as multi-stage cross-media fluxes. Second, we identify key cross-media control nodes using a chain-level hubness indicator from weighted and current-flow betweenness, and calculate cross-media emission efficiencies to quantify medium-specific outputs. Third, to flag chains where pathway amplification and outlet intensity co-occur, we non-compensatorily couple hubness with efficiency into a composite hotspot, and use ridge-regularized partial correlations to rank composite risk for co-control. This framework is applied to the Guangdong-Hong Kong-Macao Greater Bay Area, covering 61 multi-stage chains (30 for crop straw, 10 for livestock manure, and 21 for kitchen waste). Rankings are robust to ±5% edge-weight perturbations, with anaerobic digestion as a backbone node. Chain mapping yields two archetypes: multi-node trunks and single-bottleneck short routes. Cross-media efficiencies are stable, with carbon and sulfur predominantly to air, nitrogen to water, and phosphorus to soil. Highest composite-risk chains are C20 (straw: AD-biogas power-digestate landfilling), L1 (manure: open anaerobic lagoon), and K12 (kitchen waste: whole-substrate AD-biogas power). Findings prioritize gas capture and cleaning, liquid polishing, and monitored containment, providing a generalizable route to multi-element cross-media control.

The central focus of this study is to offer a micro-level examination of how Nordic short-sea shipping company representatives describe their role within the energy transition. We employed narrative analysis on RoPax/RoRo, a segment of short-sea shipping, company representatives to elucidate how elite interviewees narrate challenges and barriers to transitioning to low-emission fuels. The analysis revealed tensions related to the energy transition, namely concerns about IMO and EU policies not supporting technological change, technological and infrastructural limitations of transitioning, and the struggle to engage customers with the energy transition. Additionally, interviewees illustrated their knowledge of different decarbonization options, including the technical and commercial feasibility of different fuel options, alongside commenting on their involvement in the current policy environment. Interviewees expressed that their customers, both cargo and passenger, were unwilling to pay for the energy transition, many arguing that the customer should pay for the transition costs. Industry representatives could narrate their visions and pathway to their company's 2035 targets, but their narration of how to reach 2050 goals indicated a limited ability to only storify the sector's potential future accomplishments, but not how their company would reach the same targets. Nordic RoPax/RoRo Managers and C-level executives may have the drive or interest for transitioning to low-carbon fuels, but the lack of alignment with infrastructure, policy making that aligns with current technological know-how, cultural, users, and markets, and distribution systems makes transitioning a wicked problem.

Microplastics (MPs) are widespread in sewer systems, but how different MPs affect methane emissions from sewer systems remains unclear. Three typical MPs, non-biodegradable MPs (polypropylene (PP) and polyamide (PA)), and biodegradable MPs (polylactic acid (PLA)), were added to the sewer sediments at different concentrations (7 and 20 particles/gww TS) and incubated for 70 days. The effects of PP and PA on methane production were concentration-dependent: the addition of PP increased methane production by 16.90%–20.40%, while the addition of PA decreased it by 9.11%–54.67%. By contrast, 20 particles/gww PLA produced the most significant increase in methane relative to the control. MPs promote the decomposition of 15%–50% of organic matter in sewage sludge. Simultaneously, the change in enzyme activity depends on the properties of the MPs. Microbial community analysis indicates that MPs reduce microbial diversity, with variations observed. These findings reveal the effect of MPs on methane emissions in sewers and the mechanisms by which MPs modulate the "organic matter-reactive oxygen species-enzyme activity-microorganisms" pathway to affect methanogenesis. The study provides valuable insights into the environmental impact of MPs in sewer systems and their effect on methane production.

The study provides valuable insights into the environmental impact of MPs in sewer systems and their effect on methane production.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"176 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146115795","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}
