Despite this, MFA is gaining traction as a decision-making tool also within companies. This research examines MFA's application to fertilizer flows in green chemistry, and circularity indicators to promote healthy soils rich in organic matter/biodiversity while minimizing environmental impacts. The first substance flow analysis indicators for phosphorus management were introduced in 2006, highlighting losses, stocks, and unaccounted-for flows, but the challenge remains to apply a harmonized model across multiple cases. In nitrogen metabolism, studies estimate hidden flows and storage in the agri-food system, and corporate efforts leveraging MFA can spur similar developments in nutrient flow management, particularly in agriculture.</div></div>","PeriodicalId":54228,"journal":{"name":"Current Opinion in Green and Sustainable Chemistry","volume":"50 ","pages":"Article 100971"},"PeriodicalIF":9.3,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142421550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review outlines the most recent advances in methodologies for preparing nitrogen-rich furans, focusing on 3-acetamido-5-acetylfuran (3A5AF), dihydroxyethyl acetamidofuran (diHAF), 3-acetamido-5-formylfuran (3A5FF), and 3-acetamidofuran (3AF) from <em>N</em>-acetylglucosamine (NAG) dehydration. In addition, the review encompasses other aromatic commodities currently obtained from chitin, either by derivatization of the aforementioned furans, by deacetylation-dimerization, or other strategies.
