Using a mixed-methods approach—including stakeholder surveys, thematic coding, and concept mapping—this study examines governance expectations across seven international case contexts in Europe, South Africa, and Argentina. The results reveal pronounced differences across groups: businesses and investors prioritize infrastructure, financing mechanisms, and market stability; farmers emphasize land-use flexibility, compensation schemes, and long-term support; policymakers and environmental and conservation organizations focus on regulatory coherence, biodiversity protection, and inclusive governance; while research and innovation actors call for strengthened coordination, knowledge exchange, and locally adapted monitoring systems. In Global South cases, social equity issues—especially related to land access, participation, and benefit sharing—emerged as critical concerns. Across groups and countries, shared expectations for biobased products centered on climate and biodiversity benefits, affordability, traceability, and alignment with local needs and CE principles. Concept mapping illustrates interlinkages between stakeholder-defined priorities, governance gaps, and technical constraints, offering insight into underlying sustainability trade-offs. The findings highlight stakeholder governance as a central enabler of CE transitions, emphasizing the need for multi-level, participatory coordination, stable financial support, and cross-sectoral alignment.

The analysis covers the entire battery life cycle, using real-world load profiles from a Thai fruit export community and projected electricity mixes under three national decarbonization pathways. Environmental performance is assessed across four impact categories: global warming potential, freshwater ecotoxicity, human non-carcinogenic toxicity, and mineral resource scarcity. Results highlight that the battery production and primary use phases contribute most to environmental impacts. However, second-life use can significantly offset emissions, especially in carbon-intensive grid scenarios. In the second-use phase, sensitivity analysis showed that variations in capacity degradation and usable cell rates did not affect the total energy savings or environmental outcomes when the lost capacity was compensated by additional repurposed batteries. Among all scenarios, repurposing batteries before recycling under “30% reduction in carbon intensity by 2030” policy achieved the highest overall sustainability score, offering a balanced reduction across all impact categories. Expert-weighted impact factors further enhance the robustness of the assessment.

Nonetheless, even if drastic steps are taken today to reduce the production of textiles, the textiles already in circulation eventually need to be disposed of or recycled. To capture these garments and increase the quantity of textile available for recycling, the European Union (EU) has mandated the separate collection of the textile fraction across member states from 2025. However, collecting textiles for recycling does not guarantee that the collected textiles are recyclable. This study explores the recyclability of textiles by analysing the anatomy of textiles (linings, disruptors, adornments, and fibre blends) in Denmark and applies these findings to forecast the material available to different recycling routes in 2025. This study finds that in Denmark, after initial collection and sorting, textile complexity will likely result in the incineration of 36 % of textiles sent to recycling streams, 53 % will require disruptor removal, and 11 % will be available to different recycling routes. When the recycling capacity for high-quality recycling is considered, only a minor part (&lt;2 %) of textiles in the Danish market can result in high-quality fibre-to-fibre recycling. These results emphasize the importance of considering textile anatomy both when designing textiles and determining recycling pathways. Moreover, our findings underscore that the Circular Economy (CE) transition cannot rely on recycling alone; instead, it must invest in avoidance and reuse approaches in addition to improved sorting and pretreatment facilities within Europe to best utilize the textiles currently in circulation.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 127-142"},"PeriodicalIF":9.6,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144865175","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}

As a novel contribution, the GR system was designed using <em>Pereskia aculeata</em>, a resilient, edible, and underutilized plant species, and included the analysis of rainwater retention impacts during the roof's use phase. The methodology was structured in three stages: (1) comparison between CR and GR systems, considering construction and the roof's first year of use; (2) sensitivity analysis of alternative materials for GR components, complemented by uncertainty analysis; and (3) a 30-years projection of use-phase impacts. Primary data were obtained from GR experimental prototypes monitored over one year, including irrigation volumes, plant development, and rainwater retention from 50 rainfall events. Secondary data were modeled using the ecoinvent database and literature sources. In the first stage, GR outperformed CR in 11 of 14 impact categories, with total normalized impacts 13 % lower. In CR, 80 % of impacts were from ceramic tile production, while in GR, polymer components were most impactful, polypropylene accounted for 82 % of Fossil Depletion and polyester for 95 % of Ozone Depletion. Sensitivity analysis showed that substituting the module and filter layers' materials with alternative polymers in GR reduced Marine and Freshwater Ecotoxicity by over 70 %. The optimized GR scenario achieved 71 % lower normalized impacts than CR and performed better in 13 of 14 categories. The 30-years projection reinforced the GR's superior performance over time. In conclusion, GR demonstrated substantial environmental advantages over CR. Additionally, GR adds value through food production, making it a promising strategy for promoting urban agriculture.

Our findings indicate that household size, age, and education significantly influence food waste levels, with individuals holding a university degree wasting less food, contrary to previous studies that analysed self-reported food waste levels. Additionally, the behaviours of purchasing the right amount of food, reusing leftovers, and defrosting items from the freezer are found to mediate the relationship between age and food waste. While purchasing the right amount of food and reusing leftovers are associated with lower food waste, households better at defrosting tend to waste more food, an intriguing and previously unreported finding.

In this context, we used an agro-economic model to predict global production changes following a demand shift towards EAT-Lancet guidelines for red meat and legume intake for the year 2030. We modelled four scenarios which apply to diverse regions, namely, the European Union (EU), EU and China, 40 % of the largest red meat eaters and the whole world. The environmental impact of these subsequent changes was quantified using consequential Life Cycle Assessment. Results show that significant environmental benefits could be achieved already when 40 % of the largest red meat-eating population shifts its diet.

For example, there would be lower acidification in Asia due to the decrease in livestock production and lower aquatic eutrophication and ecotoxicity in the Americas due to the decrease in feed production.

Given this, the objective of the present study was to assess the net environmental impact of adopting different nutrition strategies with and without supplementing rumen-protected B vitamins (RPBV, B vitamins that are microencapsulated to bypass rumen degradation in cows and be absorbed in the small intestines) in dairy milk production. Seven representative regional dairy production systems across the United States, Canada, Mexico, Chile, Colombia, Australia, and France were investigated, utilizing a total mixed ration (TMR) feeding program supplemented with 3 g of RPBV. The estimated climate change impact scores for all control production scenarios ranged from 1.08 to 1.65 kg CO₂-eq/kg fat protein-corrected milk (FPCM). However, the impact of climate change per kg of FPCM decreased by 5.6–18.0 % when RPBV was supplemented on top of the TMR feeding program. The highest and lowest climate change impact reductions were observed for the RPBV production scenarios in Mexico and Colombia, where the impacts decreased from 1.65 to 1.36 kg CO₂-eq/FPCM and from 1.49 to 1.41 kg CO₂-eq, respectively. Additionally, the impacts of agricultural land use, water consumption, and acidification, as well as eutrophication potential, were reduced by 3.0–16.3 % (with an average reduction of 7.4 % across all scenarios) when the TMR feeding programs were supplemented with 3 g of RPBV. The observed impact reduction could be attributed to improvements in milk production, which varied across different regions, with milk yields ranging from 3.3 % to 19.4 % above those of the control production scenario. Additionally, there were reductions in enteric methane (up to 2.4 %) and nitrogen emissions (up to 10 %). In dairy cows, RPBV acts as an enzyme co-factor at the cellular level by improving the efficiency of key pathways involved in energy, fat, and protein metabolism, which consequently increases milk yield and feed efficiency. The manufacturing and transportation of RPBV to the seven regional destinations examined in the current study had a minimal impact on the total environmental footprint of dairy production systems. The null hypothesis was rejected, indicating significant differences in results, as the p-value for all impacts and pairs (control and RPBV scenarios per 500 Monte Carlo runs) was less than 0.05, which is considered statistically significant. Overall, supplementation with RPBV constitutes a valuable nutritional strategy to support ongoing efforts and innovations in driving sustainable dairy production.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 339-358"},"PeriodicalIF":9.6,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145010443","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}
