About this collection

Elemental sustainability is a concept in which each element within the periodic table is guaranteed for use by both current and future generations. The long term security of elemental supply has become an important issue at local (industrial), national and continental levels. Elements are not “running out”, but rather are being dispersed throughout the technosphere, making recapture both highly problematic and often costly. These challenges must be tackled through the development of multidisciplinary partnerships, which adopt sustainable holistic approaches, consistent with recovery and reuse.

This themed issue of Green Chemistry will tackle the issues of elemental sustainability and criticality of resources head on, containing both original research papers and review articles. The guest editors for this themed collection are James Clark (University of York, UK), Andrew Hunt (University of York, UK), Avtar Matharu (University of York, UK) and Alex King (Ames Labs, USA).
