About this collection

The world is scattered with unique materials with special functions that enable a whole world of consumer technology. However, supplies of these precious elements are limited and current recycling processes are inadequate. Manufacturers, retailers and investors can play their part by building sustainability into technology from production. Chemical scientists are key to solving the problems of electronics waste and scarcity of precious elements.

This cross-journal web collection highlights the latest research published in Royal Society of Chemistry journals from chemical scientists across the world to solve this global issue. The following journals are involved: Chemical Communications, Chemical Society Reviews, Dalton Transactions, Environmental Science: Processes & Impacts, Green Chemistry, Materials Advances, Polymer Chemistry, RSC Advances, Sustainable Energy & Fuels, Journal of Materials Chemistry A and Journal of Materials Chemistry C.

Research in this collection covers various aspects relating to reducing, reusing or recycling these key precious elements in electronics: tantalum, indium, yttrium, gallium, neodymium, praseodymium, dysprosium, lithium, cobalt, aluminium and nickel. Topics include mining and extraction techniques for these elements, sustainable electronics design, recovery and extraction of these elements from electronics and recycling processes and technologies.
