While the demand for technology metals such as precious metals, rare earths, and minor metals (Sb, Co, etc.) will continue to increase, their production from primary sources is challenged by complexity and poor grade. On the other hand, waste streams are emerging as alternative sources of the technology metals with many advantages. However, the current recovery rate of these metals from the waste streams is inadequate. Therefore, promoting efficient recovery of the technology metals from municipal and industrial side streams is vital and facilitates the move towards a circular economy. Thus, innovative recycling technologies, in addition to effective waste management, are essential to enable this transition.
