Leaching is the process by which precious metals are selectively extracted from electronic waste using chemical solutions. This project looks at an innovative approach that enables the recovery of gold, platinum, and rhodium under safer and more sustainable conditions compared to conventional techniques.

Adsorption is used to capture dissolved precious metals from leaching solutions by binding them onto the surface of solid sorbents. This step enhances metal selectivity and yield, facilitating subsequent recovery and reuse in advanced applications.

Catalysis involves testing and applying the recovered metals as active components in chemical reactions, such as glycerol valorization or fuel cell applications. This step demonstrates the functional reuse of precious metals, promoting sustainability and circular economy strategies.

This activity assesses the environmental footprint, economic viability, and social implications of the process. It supports informed decision-making to align recovery strategies with the goals of sustainable development.
