Nanotechnology offers innovative techniques for extracting valuable materials more efficiently and cost-effectively. Here are some key methods:
Nanofiltration Nanofiltration membranes are used to separate and recover valuable ions and molecules from waste streams. These membranes can selectively allow certain particles to pass while blocking others, making them highly efficient for resource recovery.
Nanoparticles Engineered nanoparticles can be employed to bind selectively to specific materials. For example, gold nanoparticles can be designed to attach to gold ions in electronic waste, facilitating their extraction and recovery.
Nanoscale Catalysts Nanoscale catalysts can accelerate chemical reactions that separate valuable materials from waste. These catalysts can be tailored to target specific reactions, increasing the efficiency and yield of the recovery process.
