E-Waste to High-Purity CuO Nanoparticles: Profitable & Green
Production of High Purity Copper Oxide Nanoparticles from Depopulated Printed Circuit Boards (E-Waste)
Tags: Bhabha Atomic Research Centre, India, Energy & Environment, Science & Exploration
The technology enables the production of high-purity copper oxide nanoparticles (CuO NPs) from electronic waste through a scalable hydrometallurgical process using a novel polymeric resin. The process involves the selective recovery of copper from printed circuit boards (PCBs) and subsequent conversion into CuO NPs, with by-products like lead sulfide and tin oxide also being recovered. This method offers an environmentally friendly solution to e-waste management while providing significant commercial opportunities for metal recyclers. Applications include electronics manufacturing, sensors, solar cells, and anti-microbial coatings. The technology is cost-effective, utilizes commercially available equipment, and transforms hazardous e-waste into valuable resources.
