Ensuring sustainable fisheries is essential to protect the ecosystem and dependent communities. This study explores how sustainable HMES fisheries truly are, using a modified Rapid Appraisal for Fisheries (RAPFISH) approach. We based our assessment on the hypothesis that current fishing practices may be less sustainable, largely due to challenges across five dimensions—ecology, economy, social, technology, and governance. Multi-dimensional scaling was used to score 45 attributes, followed by leverage analysis to identify key drivers. Data were collected from 38 fishing sites across four zones (8029 km²), including 238 fisher interviews, focus group discussions (4), key informants, and secondary sources. Species- and zone-specific RAPFISH results showed sea catfish fisheries as the most sustainable (57.01 %) and tiger prawn seed fisheries as the least (34.34 %). None of the 22 fisheries were in ‘good’ (75.1–100 %) or ‘poor’ (0–25 %) categories, suggesting room for improvement. Marine zone II (MZII) was “quite sustainable” (53.83 %), while marine zone I (MZI), true estuary (TE), and freshwater (FW) zones were “less sustainable” (25.1–50 %), largely due to lower scores in social, governance, technology, and ecology. Overall RAPFISH scores for HMES were 47.06 % (species-based) and 46.7 % (zone-based), indicating a “less sustainable” status. Although economic and governance dimensions showed moderate strength, zone-specific actions—such as conflict resolution (TE, MZI); enhancing vessel registration and fishing bans (FW, TE); and consolidating governance in MZII, etc., can build resilience and support sustainable estuarine fisheries.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"19 ","pages":"Article 100325"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027861","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}

This study evaluates the techno-economic and environmental performance of an integrated POM system incorporating palm oil mill effluent (POME) treatment, empty fruit bunch (EFB) composting, and residual oil recovery within a unified flowsheet. A detailed simulation model of a 60 MT/h mill was developed using SuperPro Designer® software, based on actual mill operations and literature data. The model assessed mass and energy balances, capital and operating costs, and carbon dioxide (CO₂) equivalent emissions. Results showed a 5 % increase in revenue through by-product valorization and a 53 % reduction in CO₂ equivalent emissions when combining EFB composting with biogas capture. The system achieved a positive net present value (NPV) of MYR 75.63 million, an internal rate of return (IRR) of 30.08 %, a return on investment (ROI) of 19.20 %, and a payback period (PBP) of 5.21 years. Sensitivity analysis showed that the prices of fresh fruit bunches (FFB), crude palm oil (CPO), and the CPO yield are key factors influencing economic performance. These outcomes highlight the feasibility of implementing circular economy principles, where waste streams are transformed into valuable products such as compost, biogas, and recovered oil, thereby closing material loops and reducing environmental impact.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"19 ","pages":"Article 100323"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047604","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}

Smart waste management has emerged thanks to the rapid development of digital technologies. Among these, thanks to their capabilities, Digital Twins (DTs) have recently emerged as promising for advancing CE initiatives; however, their functionalities in the electronics sector in supporting CE practices have not been analysed to a great extent. This article aims to provide a comprehensive view on current functionalities of DTs across electronic devices lifecycle, assessing how and for which purpose they are applied, highlighting challenges to CE. The article presents a systematic literature review which focuses on DT functionalities such as level of application (i.e., component, product, process levels), lifecycle phases supported, and the types of data collected in current DT applications. The main findings reveal that most of current DT implementations overlook CE aspects, mainly due to the limited data reuse across lifecycles. Building on these results, the paper proposes a conceptual scheme of guidelines that systemically incorporates DTs into CE workflows, optimizing their use for enhanced circularity throughout electronic devices lifecycle at different levels of application. The developed analysis aims at presenting how to advance DTs as enablers of circularity and provides practical insights for electronics value chain actors in transitioning toward circular practices, by leveraging the potentials of DTs.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"19 ","pages":"Article 100374"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145623623","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}

We introduce a process that evaluates these ecosystem sites using four technical factors: energy consumption volume, wind and solar energy potential, and energy infrastructure availability.

We applied this approach in the region of Päijät-Häme, Finland, identifying seven potential sites, with Kujala and Nastola standing out as the alternatives having highest potential. Higher energy consumption density or solar energy availability did not always correlate with better synergy potential. Instead, the results showed that energy ecosystem potential is formed from a combination of factors, of which energy infrastructure is the most important one in the regional case.

Housing affordability is a global challenge, particularly relevant in developing countries where informal settlements are prevalent. This research addresses the need for sustainable construction practices in these contexts, focusing specifically on wall construction as a critical building element. The study relies on MIVES, a multi-criteria decision-making method, to evaluate the environmental, economic, and social impacts of each alternative. The eight alternatives include variations of soil-cement blocks (precast and on-site produced), ceramic blocks, concrete blocks, and precast concrete panels, with and without mortar and plaster coatings. A hierarchical requirements tree, encompassing criteria and indicators related to resource consumption, emissions, cost, empowerment, safety, comfort, and innovation, was developed based on technical literature and expert knowledge. Weights for these criteria and indicators were determined using the Delphi technique. Value functions were used to standardize quantitative indicator values onto a 0-to-1 scale. This research aims to provide a structured framework for evaluating the sustainability performance of different wall construction techniques in rural informal settlements, thus providing valuable insights for informed decision-making in self-built housing projects. Results indicate that concrete blocks and precast concrete panels without coatings achieved the highest sustainability index, primarily due to their lower economic costs and environmental impacts. Conversely, ceramic blocks with coatings achieved the lowest sustainability performance. Alternatives without coatings were generally preferred due to their lower costs, aligning with real-world practices in rural areas where economic constraints govern material choices. However, these alternatives performed less favorably in terms of social sustainability, particularly in comfort and community acceptance. Sensitivity analysis confirmed the robustness of the evaluation framework across different weighting scenarios, with economic, environmental, and social biases leading to only minor ranking shifts. The findings highlight the importance of balancing cost-effectiveness with durability and habitability in self-built housing, emphasizing the need for innovative solutions, particularly in self-built soil-cement blocks, to improve sustainability while maintaining affordability.</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"19 ","pages":"Article 100348"},"PeriodicalIF":4.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145324760","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 scope of the study is from cradle-to-gate and the functional unit is defined as the “treatment of 1 t of SCGs”. The results indicate that fuel pelletizing is the best option from the environmental point of view, with all 19 impacts considered being net-negative. Pyrolysis and anaerobic digestion are the second-best options with 18 net-negative impacts, followed by the combination of transesterification with pyrolysis, with 13 net-negative impacts. Transesterification and fermentation is the worst option for 16 categories, including climate change, due to the lowest credits from the products produced. The results of the economic sustainability assessment reveal that all options earn profits and are economically feasible. Pyrolysis is the most economically sustainable alternative with a profit of £172/t SCGs, which is 2–3 times higher than for the other options. Transesterification and fermentation is again the worst option but still earning a profit of £58/t. Applying multi-criteria decision analysis reveals that pyrolysis is the best and transesterification and fermentation the least sustainable option.
