Many advanced engineering applications, such as clean-energy production, communications and computing, use emergent technologies that utilize numerous chemical elements.[4]
In 2013, the U.S. Department of Energy (DOE) created the Critical Materials Institute (CMI) to address the issue.[10] In 2015, the European COST Action TD1407 created a network of scientists working and interested on TCEs, from an environmental perspective to potential human health threats.[11]
A study estimated losses of 61 metals to help the development of circular economy strategies, showing that usespans of, often scarce, tech-critical metals are short.[12][13]
