Recovery of critical and precious metals from E-Waste
Global NEST International Conference on Environmental Science & Technology, 2022Waste of Electrical and Electronic Equipment (WEEE) is the fastest growing waste stream in Europe. This waste contains a high amount of critical and valuable metals as the rare earths defined critical materials from European Commission (2010) and the precious metals.

A review on recovery processes of metals from E-waste: A green perspective
Science of The Total Environment, 2023E-waste management has become a global concern because of the enormous rise in the rate of end-of-life electrical and electronic equipment's (EEEs). Disposal of waste EEE directly into the environment leads to adverse effects on the environment as well as on human health.

Waste electrical and electronic equipment (WEEE) is an important secondary resource of metals and critical raw materials. Printed circuit boards (PCBs), which account for the major fraction of valuable metals in e-waste, are mainly recycled using pyrometallurgy, though there is currently no suitable option for low-grade PCBs and more generally a lack ...

Sustainability of metal recovery from E-waste
Frontiers of Environmental Science & Engineering, 2018The issue of E-waste disposal is concerning all the stakeholders, from policymakers to the end users which have accelerated the research and development on environmentally sound disposal of E-waste. The recovery of metals (gold, tantalum, copper, iron etc.) from E-waste has become an important focus.

Cost-benefit analysis of metal recovery from e-waste: Implications for international policy
Waste Management, 2021The e-waste problem needs be tackled under a global framework, based upon the understanding that e-waste is a global issue and thus a shared responsibility. To illustrate this point, a cost-benefit analysis of metal recovery from e-waste was conducted with Europe, North America and China as representative regions of e-waste producers.

Recovery of precious metals from spent e-waste materials
2021•Electronic waste (e-waste) has become an important environmental and economic concern. •E-waste is any consumer electronic product–TVs, computers, phones, home entertainment systems, and household appliances–that becomes part of the waste stream when these items are discarded and replaced with newer, faster models.[1] • •Technologies for recycling

Recovery of non-metallic useable materials from e-waste
ChemosphereTremendous amounts of electric and electronic wastes (e-waste) are generated daily, and their indiscriminate disposal may cause serious environmental pollution. The recovery of non-metallic materials from e-waste is a strategy to not only reduce the volume of e-waste but also avoid pollutant emissions produced by indiscriminate disposal of e-waste ...

Waste Management, 2022
The heterogeneous nature of e-waste, which is a rich source of metals, polymers, glass fibres and ceramics, is troublesome. Multi-step processes are employed to effectively treat e-waste with minimum environmental impact. In this research, a subcritical to supercritical methanol environment was investigated to pre-treat e-waste, recovering non-metallic

Green Recovery of Precious Metals from E‐waste via Autocatalytic Leaching
Angewandte ChemieAbstract The escalating global demand for precious metals necessitates sustainable recycling from secondary resources like electronic waste. Conventional leaching techniques, however, remain constrained by their dependence on volatile solvents, external catalysts, and energy‐intensive operations.
