Companies can enhance Europe's resilience and gain a strategic advantage by systematically mapping and actively managing their company-specific raw material risks. For example, they can proactively align their Circular Economy, supply chain or investment strategies accordingly. This study creates a foundation for scientists to enable companies to realise the synergies of corporate raw material criticality assessments. A literature review is combined with semi-structured interviews with industry experts. Results show that company-specific data is the main opportunity for customisation, uncovering company-specific risks and progress, but are rarely included. Less than 5 % of the investigated environmental, social and supply risk indicators are company specific. Furthermore, varying assessment levels impede linking of risk evaluation and mitigation. Only two methodologies considered Circular Economy strategies beyond recycling. Overall, the variance in reporting and information depth poses a major challenge for application. A methodology profile is developed for prospective methodologies as means to provide an standardised overview and underscore their distinctive features. The profile and our raw material risk management cycle facilitate companies’ application and scientists’ further development. Prospective research avenues concern the linking of assessment levels, systematic coupling of risk mitigation measures, risks associated with secondary materials, risks in the downstream value chain and new opportunities arising from the digital transformation.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"219 ","pages":"Article 108299"},"PeriodicalIF":11.2,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844672","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}

We discover that the three countries exhibit distinct levels of current and attainable circularity. However, when circularity is alternatively measured against each country's responsibility for primary material extraction, the three countries are strikingly similar. This outcome highlights the need to reevaluate the circularity gap concept, advocating for a narrative grounded in scientific evidence and reflecting what is realistically achievable for economies with diverse roles within global supply chains.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"219 ","pages":"Article 108319"},"PeriodicalIF":11.2,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844739","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, combining meta-analysis and experiments, identifies N application rate as a key factor in DN's impact on CH₄ emissions. DN is more effective at CH₄ emission mitigation with higher N application rates, mainly through reducing organic matter decomposition and suppressing soil <em>mcrA</em> gene abundance.

However, traditional electrodeposition process is usually carried out under strong acid or alkaline systems, accompanied by the side reaction of lead dioxide. This study proposed a closed-loop ammonium acetate leaching-electrodeposition route for metallic lead recovery from spent lead paste. The spent lead paste was firstly leached by a neutral leaching solution of NH<sub>4</sub>Ac, HAc and H<sub>2</sub>O<sub>2</sub>. After filtration, the leaching solution was electrodeposited to produce metallic lead. Anion exchange membrane was introduced to avoid anodic lead dioxide generation in the electrodeposition process. Under the optimal conditions, the cathode current efficiency and energy consumption were 91.62 % and 625 kWh/t Pb, respectively. The NH<sub>4</sub>Ac leachant was regenerated from the eletrolyte by removing soluble SO<sub>4</sub><sup>2-</sup> with addition of Ba(Ac)<sub>2</sub> to generate BaSO<sub>4</sub> by-product. The regenerated NH<sub>4</sub>Ac leachant was then reused in the next-round leaching process, thus realizing a closed-loop process. In five leachant recirculation processes, the leaching ratio, electrodeposition ratio and total recovery ratio of lead remained relatively stable, within the ranges of 95.7–97.3 wt %, 98.6–99.6 wt % and 94.4–96.4 wt %, respectively. By upgrading of the metallic Pb product, the purity could finally reach 99.998 %.
