However, fast charging can accelerate battery degradation, reducing the battery's lifespan. To address this challenge, batteries and cooling systems are being developed with enhanced capacities to support fast charging. This paper evaluates the environmental impacts of such improved systems using a comparative cradle-to-grave life cycle assessment. The performance of the enhanced system is compared to that of a reference system currently available on the market, under two scenarios: an overnight charging scenario and a fast-charging scenario. An additional scenario is modeled to reflect a limit on the number of fast charges per month to avoid battery replacement. While most existing studies that include battery degradation look at fast-charging effects, they often do not define scenarios based on individual user charging choices and therefore, potential switch between fast and slow charging. In this study, the functional unit is 1 km driven, and the need for battery replacement is calculated using results from ageing tests at the cell level. A sensitivity analysis is also conducted to evaluate the influence of a more decarbonized electricity mix. In the overnight charging scenario, for Ecotoxicity Freshwater, the reference system performs better. Under fast-charging scenario, the improved system outperforms the other across all impact categories. With a decarbonized electricity mix, the reference system performs better across more categories in the overnight charging scenario. Overall, the study demonstrates that the comparative environmental results of the two systems depend strongly on the charging scenario.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 274-287"},"PeriodicalIF":9.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144932823","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}

This study examines the potential of an increased use of biobased materials in the Swiss residential building stock to mitigate emissions while increasing biogenic carbon storage. Using a Python-based building stock model, the study evaluates the effectiveness of increasing the share of biobased materials in both renovations and new constructions under different scenarios compared to climate goals. Results indicate that renovations will become the dominant driver of building stock emissions and biogenic carbon storage potential by 2050. While new construction activities will decline due to demographic trends, renovations will contribute nearly four times more to GHG emissions than new buildings. Nevertheless, new constructions are more effective at storing biogenic carbon, achieving a biogenic-to-emissions ratio of 300 % by 2050, compared to 176 % for renovations. By mid-century, the yearly biogenic carbon storage in buildings could reach 2.5 Mt. CO₂, approaching a balance with yearly GHG embodied emissions. However, even in the most optimistic scenario, increasing biobased material use alone reduces cumulative emissions by only 5–8 % compared to business as usual, underscoring the need for additional emission reduction strategies, including decarbonizing material production and reducing construction activities. The long-term analysis reveals that biogenic carbon storage potential is constrained by demolition rates (assuming full re-emission at the end of life), with a higher demolition rate accelerating carbon turnover and limiting storage capacity. A cumulative maximum biogenic carbon stock of 300–400 Mt. CO₂ is projected in the long-term, surpassing Switzerland's expected cumulative net emissions removals by 2050 by 6 times. This study highlights the built environment's potential as a long-term carbon reservoir and emphasizes the necessity of targeted renovation strategies, regulatory policies, and material production improvements to achieve climate goals effectively.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"59 ","pages":"Pages 229-240"},"PeriodicalIF":9.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144906926","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}

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 (<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":"2025-10-01","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}

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.

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.
