Metal Recovery from Wastes: A Review of Recent Advances in the Use of Bioelectrochemical Systems

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(3), P. 1456 - 1456

Published: Jan. 31, 2025

The rapid technological advancements and the shift towards clean energy have significantly increased demand for metals, leading to an increasing metal pollution problem. This review explores recent advances in bioelectrochemical systems (BES) recovery from waste, especially Acid Mine Drainage (AMD) Electrical, Electronic Wastes (EEW) waste smelters, highlighting their potential as a sustainable economically viable alternative traditional methods. study addresses applications limitations of current BES techniques. BES, including microbial fuel cells (MFCs), electrolytic (MECs), Microbial Desalination Cells (MDCs), offer promising solutions by combining processes with electrochemical reactions recover valuable metals while reducing requirements. categorizes research into two main areas: pure coupled other technologies. Key findings include efficiency recovering like copper, chromium, vanadium, iron, zinc, nickel, lead, silver, gold integrating enhance performance. Despite significant progress application recovery, challenges such high costs slow kinetics remain, necessitating further optimize materials, configurations, operational conditions. work also includes economic assessment guidelines development upscale. underscores critical role advancing mitigating environmental impact pollution.

Exploring the E-Waste Crisis: Strategies for Sustainable Recycling and Circular Economy Integration

Recycling, Journal Year: 2025, Volume and Issue: 10(2), P. 72 - 72

Published: April 14, 2025

Electronic waste (e-waste) is the fastest-growing stream on planet, yet it remains critically under-addressed in global management and recycling efforts. The rapid pace of technological advancement has led to increased consumption electronic devices, many which are challenging costly recycle efficiently. Insufficient infrastructure for e-waste resulted large quantities being exported countries with minimal capabilities. In these regions, often processed manually, exposing workers hazardous materials toxic elements commonly found components, leading serious health risks. E-waste consists primarily fibrous composite plastics mixed valuable metals reusable components. While recovered, remaining typically discarded, contributing significant environmental harm. Addressing challenges requires more than just solutions. United States, limited policies promote large-scale reuse practices, particularly among corporations. To build a sustainable approach, combination next-generation, cost-effective chemical technologies forward-thinking policy reforms will be essential effective reduction e-waste. This paper explores generation composition e-waste, highlighting its impacts due improper handling disposal. It reviews current emerging while examining opportunities management. Finally, discusses solutions future directions improving through innovative reforms, concluding recommendations circular economy approach.
