This study develops an integrated assessment framework combining the Simulated Uncertainty Range Evaluations (SURE) method, a combination weighting approach, and a five-criteria indicator system: technological performance, resource utilization, environmental impacts, economic feasibility, and societal impacts. The framework explicitly incorporates uncertainty to enhance decision-making robustness. A case study of major Chinese recycling technologies, named rubber powder production, reclaimed rubber production, pyrolysis, and tire retreading, was conducted. Findings emphasize the pivotal role of technology maturity (T2), resource utilization rate of solid waste (R5), fossil resource scarcity (E5), product added value (ECO3), and employment opportunity (S1) within their respective criteria. Technological performance and environmental impacts were the most critical criteria, with weights of 0.369 and 0.225, respectively. Rubber powder production led in sustainability with a mean score of 0.300, followed closely by pyrolysis at 0.295, both excelling in resource and environmental performance. Reclaimed rubber production scored 0.208, while tire retreading, despite its excellent economic and societal performance, lagged behind with a score of 0.196 due to lower weights assigned to these criteria. Given the dominant weight of technological performance, the sustainability gaps for reclaimed rubber production and tire retreading can be most effectively narrowed by improving their technology compliance (T3), while the resource and environmental advantages of rubber powder production and pyrolysis justify prioritizing their adoption through targeted support, such as financial incentives and information dissemination. Sensitivity analysis under alternative uncertainty distributions confirms the robustness of these rankings.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"21 ","pages":"Article 100455"},"PeriodicalIF":4.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148183764","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}

The framework covers collection, transportation, treatment, and avoided product utilization, considering different cluster sizes and technologies. Four conceptual scenarios were modeled: reference, current, waste management master plan, and improvement scenarios incorporating centralized and on-site systems. Results show that landfilling and incineration are major contributors to global warming, acidification, and eutrophication, while recycling and energy recovery technologies, including refuse-derived fuel (RDF) with waste-to-energy (WTE), substantially reduce impacts. Effective strategies vary by cluster size. For large clusters, optimal integration includes anaerobic digestion, composting, RDF with WTE, recycling, and landfilling. Medium clusters benefit from composting, RDF with WTE, recycling, and landfilling, whereas small clusters are best served by on-site home composting, incineration with WTE, recycling, and landfilling. A diversion of 95 % of waste from landfills, combined with a 30 % recycling rate, can lower climate change impacts by nearly 200 %. Sensitivity analysis indicates that reducing MSW transport distances further decreases impacts. Applying spatial differentiation in Life Cycle Impact Assessment (LCIA) and using different LCIA methods yielded consistent trends. Overall, the proposed framework supports the development of carbon-neutral MSW management systems by optimizing technology integration, maximizing recycling and energy recovery, and minimizing landfill disposal.

This review provides a systematic and quantitative evaluation of 113 peer-reviewed studies published between 2003 and 2025, highlighting the key chemical and physical parameters that govern fresh-state behaviour. The research identifies the critical influence of activator molarity (1–16 M), water-to-binder ratio (0.30–0.50), and sodium silicate-to-sodium hydroxide ratio (1.5–3.0) on slump flow and viscosity, demonstrating that optimized formulations can achieve slump values of 180–250 mm and compressive strengths above 55 MPa without segregation. By integrating statistical comparisons and sustainability analysis, this work introduces a novel framework that links rheological parameters with carbon footprint, material efficiency, and constructability performance. A comprehensive life cycle assessment (LCA) framework is presented, evaluating multiple environmental impact categories including global warming potential, water consumption, acidification, eutrophication, resource depletion, and toxicity indicators across the full production-to-end-of-life spectrum. Results show that improving flowability through appropriate activator design and superplasticizer dosage (3–7 wt%) can reduce energy consumption during mixing and compaction by 10–20%, while maintaining or enhancing strength and durability. The review further compares application-specific requirements in 3D printing, precast systems, and sewer rehabilitation, where controlled workability ensures structural integrity and rapid placement.

An experiment with 21 fishing trips compared both methods. Lures yielded 26.5 octopuses and 13.7 kg per trip, versus 23.9 octopuses and 12.6 kg with bait. No differences in weight (p = 0.6) or number (p = 0.54) were found, indicating lures are as effective as bait. Based on operational data from three fishing seasons (2021–2023) and interviews with experienced fishers, we estimated the cost-effectiveness of both strategies. Lures are more cost-efficient, mainly due to their reusability. Lure-based operations had an average daily lure cost of 2.12 USD, representing a cost of 0.013USD per kg of octopus. In contrast, bait costs were estimated at USD 31.8 per day per vessel, and USD 0.46 per kg of octopus. Using artificial lures could save approximately half a ton of crabs per vessel, as each vessel typically requires around 6 kg of bait per fishing day over the 90 days commonly fished in a season, thereby significantly reducing fishing pressure on crab populations. Additional benefits of lures include improved hygiene, and no need for refrigeration for bait storing. Although made of plastic, lures contribute to reducing waste by lowering the frequency of line replacement, as bait is often discarded with the tying line. Although potential negative externalities are recognized—requiring monitoring and intervention when justified—lures present a viable solution aligned with broader local fisheries sustainability initiatives.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"20 ","pages":"Article 100377"},"PeriodicalIF":4.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145798103","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}

Environmental impacts were estimated using Life Cycle Assessment (LCA), while economic performance was analyzed using Life Cycle Costing (LCC). The functional unit was defined as a single chicory plant, and the system boundary was defined as a cradle-to-gate approach. Across all production systems, growth chambers showed significantly higher environmental and economic impacts than greenhouses, with global warming impacts reaching 2.1 kg CO₂ eq versus 0.12–0.15 kg CO₂ eq per plant, respectively, and water consumption increasing from 5 to 13 L in greenhouses to 13–15 L in growth chambers, primarily due to energy-related water consumption. Economic results showed costs ranging from €1.82–2.76 per plant in growth chambers, compared to €0.37–1.33 in greenhouses, depending on the growing technique used.

However, little empirical evidence exists on the gap between European reporting ambitions and the realistically achievable GHG reductions in manufacturing SMEs. This study reports on an eight-month action-research collaboration with two Austrian SMEs to co-develop a five-stage GHG accounting and reduction framework that guides SMEs from initially encountered lack of knowledge, resources, and data, over a baseline balance sheet to ESRS-aligned actionable decarbonization plans. In case 1, a full Scope 1–3 baseline of 9.200 tCO₂eq was compiled, leading to a 2030 forecast of 10.817 tCO₂eq. Planned engineering measures and anticipated supply chain improvements reduced this by 44%, meeting near-term science-based targets. In case 2, overcoming accounting complexities, gaps in data systems, and unknown product-use emissions, a 2023 baseline of 62.990 tCO₂eq was calculated, with 85% from downstream product use. Despite internal energy and logistics measures and supply chain gains totaling 2.549 tCO₂eq, projected 2030 emissions (84.216 tCO₂eq) remain well above Scope 3 reduction targets. The cross-case comparison reveals a persistent “GHG reduction gap” between ESRS-aligned trajectories and what SMEs can achieve given resource and data limitations. Our framework demonstrates how SMEs can systematically account for emissions and prioritize mitigation measures across energy, materials, and mobility to derive decarbonization paths. Scenario planning for GHG inventories revealed where ambition outpaces engineering reality. Implications highlight the importance of data ownership, custom templates, digital data capture, and scenario planning to translate ESRS E1 into practice, overcoming GHG accounting challenges and the reduction gap.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"20 ","pages":"Article 100406"},"PeriodicalIF":4.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147395487","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}
