REWAS, a sustainability driven conference within The Minerals, Metals and Materials Society, has a long history of bringing together academia and industry to exchange and reflect on the latest technology developments available to the metals and materials community. The first edition of REWAS took place in 1999, when the conference was launched as the leading international symposium for recycling technologies, water treatment and clean technologies. 1 At that time, the abbreviation stood for REcycling and WAste Symposium, but the scope of the conference has broadened to include many aspects of environmental sustainability. Since then, REWAS established itself as a major event for cross fertilization of thoughts and efforts on waste handling, pollution management, life cycle assessment, materials availability, and recovery. In 2004 and 2008, the conference brought together diverse organizing societies across the world from academic, industrial, and governmental bodies. The 2008 edition coincided with the formation of the Materials & Society Committee of TMS, that supported and promoted resource sustainability concepts within event programming and publications. Since 2013, REWAS is held every 3 years and hosted by the TMS Annual Meeting. [2][3][4][5] . Inspired by the initial scope and strengthened by its organizers, REWAS has grown to include resource management and manufacturing efficiency, liaising these developments to the metallurgical industry in a broader societal and systemic context. [6][7][8][9] . In particular, the symposium puts an emphasis on product-centric approach and the links between product design, manufacturing and recycling within the metals industry, as well as on the development and implementation of new tools and metrics for sustainability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
