Abstrakt

In this
article, current progress in urban mining related to e-waste recycling is
reviewed and associated state-of the-art recycling technologies are evaluated.
As sufficient volume of e-waste is a limiting factor for its recycling economy,
the need for the establishment of effective e-waste collection mechanisms,
particularly for small sized End-of-Life (EoL) devices, is emphasized in terms
of the need for effective government policies, increased public awareness,
economic incentives, establishing industry-funded co-regulatory agreements,
etc. Feasible options for e-waste recycling through pyro- and
hydro-metallurgical process routes are reviewed. Deficiencies in e-waste recycling
chains are highlighted, and recommendations to improve the current very low
collection rate of small sized EoL devices such as mobile phones are made.
Optimization of the recovery of the critical metals and energy through
different processing options is discussed.
