An Analysis of E-Waste Recycling Technologies from the Chemical Engineering Perspective
Technological advancements and changes in lifestyle have led to the generation of a behemoth amount of e-waste worldwide. The demand of new Electrical and Electronic Equipment (EEE) is also increasing which is leading to rapid depletion of primary resources. Resource recovery and recycling of e-waste is the only option to keep things in balance. There are many technologies for e-waste recycling which are in practice, such as pyrolysis, gasification, leaching, biosorption. Reported literature includes stand-alone experimental works, sustainability analysis and systematic reviews of e-waste recycling technologies. Most of these recycling processes have some chemical engineering aspects which are inherent but yet overlooked in most of the cases. Studies envisaging the chemical engineering aspects of these technologies are scant. In this study, a detailed analysis of these e-waste recycling technologies from the chemical engineering perspective has been presented. Transport properties, kinetics, thermodynamics, etc., have been taken into consideration for carrying out the analysis. The findings of this paper will enable the researchers in this field for further process development.
