In order to adopt the CE as common practice, there is a need to reimagine the product end-of-life (EoL) phase to include assessment of individual component health status. Implementation of EoL strategies on products designed based on wear and tear, robustness, and safety concerns is, however, complex. The purpose of this study is to explore the potential of designing for CE by applying a visual health-based analysis (VHA) at the component level at the EoL stage. The application of this diagnostic tool is exemplified in a case at a large Swedish outdoor power product manufacturer by analyzing components for reuse, remanufacture, refurbishment, recycling, and recovery strategies. The VHA results in the calculation of a CE potential at the component-product level based on individual component's cost, complexity, health, and diagnostic approach. This study presents a diagnostic tool for practitioners to understand circularity at the component-level in the effort to identify EoL strategies. Furthermore, in supporting the CE principle of maximizing resource recovery, the study potentially contributes to the EU's CE action plan and the UN-SDGs 8, 9, 12, and 13.</p></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"51 ","pages":"Pages 67-78"},"PeriodicalIF":10.9,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352550924002604/pdfft?md5=7530106f3f4ac5e0fab5df354d4a5a72&pid=1-s2.0-S2352550924002604-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142242666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through the SCC, this work addresses the pressing socio-ecological challenges the housing sector faces, especially the need to balance housing expansion with environmental limits. In doing so, this work provides a platform to discuss the consumption-based versus absolute limits for social and ecological thresholds, the need to integrate social and environmental thresholds, and the need to model the provisioning system dynamics which in turn influence the social and environmental performance of housing provisioning systems. This provisioning includes both the physical and political economic factors which influence these outcomes.

Climate-smart agriculture (CSA) is an evolving approach to balance heightened crop productivity, reduced GHG emissions, and enhanced resource adaptability to climate change. A comprehensive model was developed to facilitate the sustainable and coordinated development of land, energy, food, and waste nexus systems. This study seeks to tackle the pressing necessity by incorporating advanced modeling techniques to enhance resource allocation and decision-making in agricultural systems, aiming for a triple win in reducing GHG emissions, enhancing food security, and promoting economic sustainability. An integrated approach harnessing life cycle assessment, system dynamics model, and multi-objective optimization methodologies was employed to evaluate the effects, trade-offs, and synergies of resource allocation in the context of CSA practices. In Jiangxi Province, China, a case study demonstrated notable reductions in overall carbon footprints, ranging from 6.02 % to 12.03 %. Additionally, applying the Non-dominated Sorting Genetic Algorithm II optimization algorithm to the model led to significant enhancements, such as an 11.24 % increase in grain nutrient availability, a 20.99 % boost in economic returns, and a 19.36 % decrease in GHG emissions. The findings underscore the efficacy of optimizing resource allocation to attain economic, environmental, and social advantages and curb carbon emissions. Moreover, pivotal policy recommendations encompass land use transformation, optimal food production allocation, and bioenergy production restructuring. Enforcing the practices of CSA and integrating them with carbon market transactions are crucial for sustainable agricultural development. This innovative framework provides a sustainable global agricultural management model with a low-carbon footprint, which is particularly beneficial in resource-scarce regions with competing policy objectives.</p></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"50 ","pages":"Pages 536-555"},"PeriodicalIF":10.9,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149151","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}

Business Models for Sustainability (BMfS) can be crucial in achieving extended life cycles and a more conscious use of materials. Due to the high interdependence and interconnectedness of different BMfS compared with traditional business models, the application of conventional approaches for the design of BMfS is limited. Therefore, we show that a systemic perspective is required to achieve absolute sustainability that transcends the boundaries of a focal company. We then conduct a two-part systematic literature review focusing on existing approaches to support a systemic perspective in the design and analysis of BMfS first and modeling approaches second. Based on this review, we identify seven general approaches to achieve a more systemic perspective and six types of approaches to modeling BMfS. We further derive ten key findings and 36 requirements for a framework for the engineering of BMfS. Based on this, we introduce a System of Systems (SoS) perspective on BMfS to enable the required systemic perspective and propose a framework for the engineering of a system of BMfS (SoBMfS) providing a systematic multi-perspective, multi-level approach bridging micro-, meso-, and macro-level.

Modelling circular economy strategies in the Life Cycle Assessment (LCA) of EV batteries comes with a number of key challenges to ensure sound support to decision-making, including i) solving multifunctionality, whether regarding End-of-Life, processes of secondary raw materials production or product level, ii) capturing material quality aspects and iii) using adequate resource indicators. This study provides a review of LCA guidelines and scientific literature relative to EV batteries. The objective is two-fold: i) identifying key gaps in the guidelines regarding these modelling challenges, and ii) discussing how to fill them based on the state-of-the-art research. The analysis shows that the handling of multifunctionality is addressed in all analysed guidelines but is treated very differently. Major efforts are expected in terms of standardisation and harmonisation, building on the existing state-of-the-art research. A guiding question for standardisation is whether multifunctionality shall be always treated in the same way or whether special rules are appropriate. Instead, material quality and indicators of mineral resource losses are not at all, or to a very limited extent, addressed by existing guidelines. For material quality and mineral resource dissipation and accessibility-based indicators, research developments shall be pursued. Associated research outcomes are ultimately expected to be fed back into the guideline development in a more mid to long-term.

The findings showed that the vehicle life cycle (manufacture, maintenance, and disposal) was a significant contributor to human health and ecosystem quality impacts when comparing across transport life cycle phases in both ICEVs and EVs.
