Then, a scenario of plastics limit order was set to analyze characteristics of greenhouse gas emissions and carbon peak potential for polyethylene terephthalate, polyethylene, and polypropylene. Certain mitigation and carbon peak strategies were proposed. Results indicated that the main pathways of greenhouse gas were the manufacturing process of polyethylene terephthalate fibers, polyethylene films, and PP woven goods. Moreover, polyethylene terephthalate, polyethylene, and polypropylene would have a significant emission reduction (equivalent to the emissions of 26 new power plants (500 MW)) by 2030 under the prohibition scenario. Notably, although substitution scenarios could reduce waste, the reduction of greenhouse gas would not be obvious. Optimizing waste management has significant effects on emission reduction. The scenario of multiple measures would contribute significantly to realizing carbon reduction and peak (PET, PE, and PP reducing by 152.2, 92.2, and 21.5 Mt CO₂e).

Our findings uncover previously unnoticed causal relationships and system interdependencies, offering new insights into the dynamics that can support or hinder potential transition pathways for a sustainable circular bioeconomy. A central outcome of this research is the identification of system-level interdependencies that influence sustainable resource management and the development of circular value chains. Furthermore, we advocate for a more detailed data level for bioeconomy technologies and offer targeted recommendations for policymakers, industry stakeholders, and researchers. These recommendations guide the practical steps needed to foster a thriving circular bioeconomy at both national and international levels. Contributing to the broader discourse on scenario-based research, the systematic-formalised approach of influence and consistency analysis underscores the importance of transparent scenario conception in bioeconomy studies. This emphasis aims to enhance the quality and effectiveness of future research efforts and scenario interpretation.

They were presented with six products (i.e. fresh/processed vegetables, dairy, and meat) and for each product, they had four levy options to choose from. For vegetables, they were: (A) reduction of risks related to plant protection products, (B) more support for local farmers, (C) support for environmental sustainability, and (D) sustainability projects in general. For the animal products, option A was an increase in animal welfare. For all three comparisons (fresh vs. processed of vegetables, meat and dairy), the number of participants who chose the general sustainability information increased for processed products compared to fresh products. Further, we found that for the animal products, the majority of participants preferred the levy that increased animal welfare. For vegetables, participants preferred a levy that reduced risks related to plant protection products and supported local farmers. We found that when the sustainability levy was not defined, it tended to be understood as environmental sustainability. Using multinomial logistic regression, we identified the perception of farmers as a significant predictor of a levy choice to support local farmers.

However, the environmental performance of treatment processes varies depending on operational configurations and external factors such as seasonal changes. This study aimed to investigate three wastewater treatment plants (WWTPs) with different biological nutrient removal (BNR) configurations -anaerobic-anoxic-oxic (A2O), five-stage Bardenpho, and Johannesburg processes- using the life cycle assessment (LCA) approach to comparatively examine their environmental performances and to conduct an LCA study using two functional units (FUs) (1 m³ of wastewater treated and 1 kg of total nitrogen (TN) removed), revealing seasonal environmental impacts for A2O process to reveal the difference in interpretation according to the FU selected. The ReCiPe 2016 methodology was employed, focusing on ten key impact categories, including global warming, marine eutrophication, freshwater eutrophication, human carcinogenic toxicity, human non-carcinogenic toxicity, marine ecotoxicity, freshwater ecotoxicity, terrestrial ecotoxicity, terrestrial acidification, and fossil resource scarcity. The results show that the Johannesburg process achieves better environmental performance compared to the others. The superior performance of the Johannesburg process can be attributed to having no fugitive methane (CH₄) emissions due to the absence of anaerobic digester in the sludge treatment and its competitive TN removal rates, which align directly with sustainability objectives like emission reduction and reducing carbon footprint. Choosing the right FU is crucial for sustainability. The FU based on 1 kg TN removed provided a more representative view of environmental efficiency under changing seasonal conditions. These findings emphasize the importance of aligning FU selection with sustainability goals. In terms of wastewater management policy, the study suggests that monitoring based on the percentage of pollutant load removed or total annual emissions generated would be more meaningful, taking into account changing external conditions such as seasonal factors.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"53 ","pages":"Pages 177-189"},"PeriodicalIF":10.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143132768","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}

However, the need for scalable and sustainable wastewater treatment technologies is critical in addressing the challenges posed by population growth and environmental concerns. These technologies still lack a comprehensive framework that can evaluate the relationships between techno-economic, environmental life cycle, socio-policy, and reliability as well as sensitivity, and uncertainty analysis. Furthermore, the reliance on expert judgment, in evaluating new technologies, while valuable, often is slow, costly, and sometimes hindered by a lack of familiarity with disruptive innovations due to experts' knowledge gaps and constrained future outlooks. Hence, this study introduces an integrated rapid sustainability assessment framework designed to evaluate pilot sludge reduction technologies across technical, economic, reliability, environmental, and socio-political dimensions. The framework leverages a data-driven, scenario-based multi-criteria decision-making approach, incorporating rigorous sensitivity and uncertainty analyses to enhance the reliability of evaluations. This framework is validated through a case study involving three alternatives: (1) Anoxic/Oxic Membrane bioreactor, (2) Anaerobic Side-Stream Reactor, and (3) Anaerobic Main-Stream Reactor. Using the proposed approach, 145,530 potential future scenarios were analysed, incorporating five key criteria and 20 vital indices. The results indicate that the second alternative outperforms the other options in 86 % of the evaluated scenarios. However, its performance may be sensitive to any changes in pollutant removal efficiency, operational costs, and global warming potential when scaled to full industrial applications. In comparison to current approaches, this user-friendly framework not only shows its ability to capture a broader range of uncertainties, but also identifies trends and potential challenges that may not be readily apparent through expert intuition alone. This method also provides a holistic view of the environmental, technical, reliability and socio-policy impacts, facilitating informed decision-making for scaling pilot technologies to industrial applications.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"53 ","pages":"Pages 163-176"},"PeriodicalIF":10.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143133049","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}

A critical aspect of this process is determining the optimal time to take a product out of operation to facilitate the implementing of an appropriate circular strategy. However, decision-makers often lack the tools and methods to effectively answer this question, making it difficult to define and implement a strategy that is both ecologically sound and economically viable. This article presents a methodology that uses the State of Health of a product as a key indicator to identify the most advantageous year for taking back the product and applying a specific circular process (i.e., reuse, remanufacturing or recycling). Based on the State-of-Health, the environmental impact and total cost of the product are calculated annually over its lifetime using defined parameters. A circular strategy is proposed for each take-back year, determined by State of Health thresholds for various circular processes. To determine the optimum take-back year, an algorithm is applied, using a weighted sum as the objective function. This methodology is implemented within a dynamic circular strategy simulation tool to support decision-making for stakeholders. The approach is demonstrated using a case study on a circuit breaker in Genset and hospital applications.

Moreover, economic development and land use carbon emissions are weak decoupled.
