The aim of this study was to integrate nutritional aspects in the assessment of environmental sustainability of food products against the planetary boundaries. Methodologically, the model was built on the approaches of nutritional Life Cycle Assessment (LCA) and a planetary boundary-based LCA (PB-LCA) that compares environmental impacts against the assigned share of planetary boundaries. Thus, the model can identify food products that provide sufficient nutrition in relation to their environmental impacts, in accordance with the criteria of the planetary health diet. As a result, we developed Nutrient Index-based Sustainable Food Profiling Model (NI-SFPM) and tested its applicability in an assessment of 559 food products across various food categories, considering the impact categories corresponding to the planetary boundaries of climate change, nitrogen cycling, phosphorus cycling, freshwater use, land-system change, and biodiversity loss. The results demonstrated the model's effectiveness in discerning between food products and food categories based on their environmental performance and nutrient composition. The resulted sustainability ranking of different food categories was in accordance with the current understanding of healthy and sustainable diets. By evaluating the sustainability of food products, the NI-SFPM enables informed decision-making for consumers, policymakers, and food industry stakeholders, assisting in optimizing production processes, sourcing sustainable ingredients, and enhancing product formulations. Through these insights, the NI-SFPM has the potential to drive positive changes in food industry by promoting the development and consumption of environmentally and nutritionally sustainable food products.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"56 ","pages":"Pages 142-155"},"PeriodicalIF":10.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759708","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}

One pathway to remove restricted substances from recirculation is through labelling strategies that inform consumers about the chemical content of products. To date, research on the influence of information about chemical content on consumers' willingness to pay for retail purchases, particular in the clothing sector, is rather limited. Using discrete choice experiments conducted in Denmark, Sweden and the United Kingdom with a sample of 1528 adults, we investigated whether access to information about the chemical content of garments influences consumer willingness to pay across new, recycled and reused clothing. Although access to information about restricted chemicals is enshrined as a right-to-know in the European Union's regulations, the study highlights low awareness of this right: <23 % of respondents in all countries have requested such information. Findings show a strong preference for either instant access to chemical information through a QR code or direct access to information printed directly on a product label. Interestingly, the choice of QR code is preferred over printed product labels. At the same time, information provided in the standard 45-day waiting period is no more preferred than no information at all. Meaningfully, consumers in all contexts are willing to pay a premium for rapid access to information for new and recycled options, but there is uncertainty regarding used options. Our results also show that up to 9 % of the respondents choose according to an elimination-by-aspects strategy, meaning they will avoid purchasing clothes without access to information about chemical content. The results strengthen the need for higher transparency and better exchange of information along textile value chains, however they also emphasize the already high uncertainty faced by circular economy enterprises.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"56 ","pages":"Pages 128-141"},"PeriodicalIF":10.9,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759709","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}

To this end, ten semi-structured interviews with silk industry experts were carried out, and a thematic analysis was conducted, integrating findings from the extant literature to enhance the depth and contextualization of the results. Six critical themes emerged: waste utilization, circular approaches, consumer education, technology advancement, traceability and transparency, and governmental regulations. The findings reveal that production waste, such as mulberry branches, silkworm litter, low-grade cocoons, and sericin, can be repurposed into fertilizers, animal feed, cosmetics, and textiles, offering both environmental and economic benefits. Circular practices like designing for product longevity, minimizing chemical usage, reusing silk garments, and promoting recycling are key to achieving resource optimization and waste reduction. Technology advancements, including artificial intelligence and blockchain, enhance efficiency and ensure traceability and transparency, fostering stakeholder trust. Consumer education is also vital for creating awareness regarding sustainable practices. Additionally, government policies play a transformative role by supporting training programs, incentivizing innovation, and driving circularity within the industry. This study proposed a theoretical framework that offers actionable insights to industry practitioners, researchers, and policymakers for embedding circularity throughout the silk industry, contributing to global Sustainable Development Goals (SDGs), particularly responsible consumption and production.

To overcome the above challenge, this study introduces the Multidimensional Disassembly Index (MDI), a structured framework to evaluate the disassembly efficiency of a product during its early design phase. The proposed approach systematically analyzes independent variables that directly impact the disassembly process and evaluate the disassembly effectiveness based on these independent variables. Through a case study, the paper demonstrates how the proposed methodology supports design improvements for easy disassembly. Using the MDI approach, the effectiveness of disassembly for remanufacturing and recycling was evaluated in a case study on a retractable ballpoint pen's design. The MDI score for remanufacturing is 9.01, reflecting ease of disassembly, while recycling MDI scored 8.74, highlighting design improvement on plunger accessibility and clicker material compatibility.

To fill this gap, this study aims at testing lifespan and end-of-life modelling choices to gain an improved understanding of their effect on the quantification of the environmental impacts of the EU residential sector, using a Life Cycle Assessment (LCA)-based building stock model developed by the European Commission – Joint Research Centre (JRC) as the reference model. Several options were explored in relation to parameters affecting the service lives of buildings and their components, along with their end-of-life pathways. A sensitivity analysis was also performed to evaluate the model's robustness when subjected to parameter changes derived from the literature. It emerged that, due to the prominent role played by the operational energy phase, environmental impact results at the stock level were not significantly affected by parameter changes, with the exception of the particulate matter impact category, which achieved >10% variations when simultaneously testing shorter finishing material service lives and lower incineration and recycling rates. Shifting the focus to embodied impacts, however, led to increased sensitivity in the model, with oscillations due to service life length overshadowing those connected to end-of-life treatment changes: in terms of single weighted score, the former can achieve a building-level variation of over 100% (when assuming short lifespans), while the latter does not exceed 38% (when maximising incineration rates). It is therefore necessary to take these fluctuations into account when using this LCA-based model as a basis for verifying the potential benefits of measures to promote circularity within the building sector, particularly as said measures primarily target embodied impacts.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"56 ","pages":"Pages 207-220"},"PeriodicalIF":10.9,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143767780","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}
