Ownership patterns were less geographically distinct but stratified by type: mixed-ownership buildings exhibited the highest embodied energy, largest material stock and the most modern buildings, whereas community-owned buildings showed the widest variation in annual operational emissions (1500–2300 kg CO₂/resident).

However, a higher degree of circularity does not automatically result in a more sustainable economy, meaning the newly published ISO59020 for circularity performance measurement and assessment demands the completion of complementary sustainability analysis to support decision making. Therefore, this work aims to complete a holistic circularity assessment in line with ISO59020, by assessing both conventional and novel production processes of a high value cosmetic ingredient, that has potential to be generated from waste-derived biogas. This was achieved by applying standardised methods for circularity and environmental (life cycle assessment), economic (technoeconomic assessment), and social (social life cycle assessment) sustainability assessment. The novel process performed poorly in terms of water and emissions circularity, meaning investments are required for water upgrading and recycling technologies, and that CO₂ emissions should be recirculated to the biogas generation plant. However, even though the process performed well across sustainability dimensions, it was clear the process was vulnerable to performance deterioration if circularity and sustainability assessment results were considered independently. Specifically, the impacts of local water usage and grid electricity did not impact sustainability performance, whilst circularity indicators showed reliance on large freshwater demands and highly renewable grid electricity to maintain performance. Therefore, the need for harmonised assessments of circularity and sustainability is clear, and further work is needed to develop robust tools for combining impact indicators into a single, easily utilised metric.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"221 ","pages":"Article 108427"},"PeriodicalIF":11.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144196342","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}

To reduce both proper and improper plastics disposal and the concomitant long and short term physical and chemical risks, recycling has emerged as an effective and complementary tool to recover waste and lower demand for unsustainable virgin plastics production. Post-consumer and post-industrial recyclate is often mixed with virgin plastic to satisfy performance criteria. To drive demand, countries such as the UK, USA and Australia have recently mandated recycled plastic content targets. Incorporation of recyclate necessitates recycled content quantification tools to prevent misleading claims about the environmental sustainability of a product. However, methods to quantify recycled content are multi-faceted, with different approaches resulting in different measurements for any one product, creating dissonance and mistrust between governments and producers. This review discusses recycled plastic content and its current role in global legislation, the mass balance approach favoured by supply chains to assure origin or composition, as well as laboratory methods to quantify recycled plastic content, according to their feasibility and authenticity. Particular focus is given to plastics in the packaging sector given their prevalence in legislation and widespread use.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"221 ","pages":"Article 108426"},"PeriodicalIF":11.2,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144178047","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}

Greenhouse vegetables have higher yields (16 % to 50 %) and lower reactive nitrogen footprints (-6 % to -33 %), but much higher carbon footprints (5 % to 46 %), than open-field vegetables.
