Abstract:
Since its conception, the periodic table and the elements contained within it have shaped our modern lives. The use of many elements is now ubiquitous and essential for the modern technologies we have now become accustomed to. However, our use of some elements may be considered as unsustainable and their current use may create both economic and environmental pressures. The United Nations have designated 2019 the "International Year of the Periodic Table". As such this Essay presents some important points on "critical elements" and the importance of adopting sustainable practices in the use of all elements of the periodic table. This article also highlights a number of examples of green technologies for elemental recovery and some of the challenges we must overcome to become truly sustainable across the whole periodic table.
