A review on electrochemical techniques for metal recovery from waste resources

Abstract Reactions on anode and cathode are crucial for efficient electrical energy within the electrocatalysis conversion operation. Electrocataffncialytic anodic oxidation followed by cathodic reduction can enhance the recovery of energy acquisition and valuable substances are produced on both electrodes. Recycling metals from waste resources significantly mitigate several environmental issues. Here in this review, we have discussed the general introduction on metals derived from waste resources, impacts of waste materials on the environment, and electrochemical recycling technologies used to recover the materials (i.e., precious metals) from waste. Finally, we concluded the topic with prospects of this proposed topic. • An overview of electrochemical techniques for metal recovery from waste resources. • Importance of the electrocatalytic reaction to recover valuable substances. • The impacts of waste materials on the environment and human health.
