Transforming E-Waste into Value: A Circular Economy Approach to PCB Recycling

This study delves into the pressing global issue of electronic waste (e-waste), with a specific emphasis on printed circuit boards (PCBs). PCBs, being a crucial component of electronic devices, contribute significantly to e-waste due to their intricate composition of hazardous substances and valuable metals such as gold, silver, and copper. The research explores the concept of the circular economy—an economic system aimed at eliminating waste through the continual use of resources—and its potential application in recycling PCBs. This involves a detailed investigation of the challenges and opportunities associated with various extraction methods and waste management strategies. The study also presents a case study on The Royal Mint’s innovative approach to gold extraction from PCBs. This practical example offers valuable insights into the application of circular economy principles in the context of PCB recycling, demonstrating how these principles can lead to improved resource efficiency, waste reduction, and economic benefits. The findings of this research underscore the need for further development and implementation of sustainable practices in e-waste management to mitigate environmental impact and capitalise on the economic potential of valuable materials in e-waste.
