14 Oct 2022 --- Researchers at the City College of New York (CCNY), US, have found that advanced recycling (AR) technologies can produce enormously different environmental impacts, with some methods and projects reducing greenhouse gas (GHG) emissions by as much as 566%, while others can produce increases of 267%. The study authors examined 13 life cycle analyses (LCA) on large-scale and commercially ready AR projects that use an array of methods, including pyrolysis, reforming and gasification. Also examined were sites using chemical depolymerization processes such as glycolysis, hydrolysis and methanolysis.
