In thisarticle, current progress in urban mining related to e-waste recycling isreviewed 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 termsof 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- andhydro-metallurgical process routes are reviewed. Deficiencies in e-waste recyclingchains are highlighted, and recommendations to improve the current very lowcollection rate of small sized EoL devices such as mobile phones are made.Optimization of the recovery of the critical metals and energy throughdifferent processing options is discussed.
