Today, with the rapid development of technology, electronic devices are being replaced at an increasingly faster pace, resulting in a large number of discarded printed circuit boards (PCBs) and integrated circuits (ICs). These seemingly insignificant components contain valuable metal resources, but also pose a potential risk of environmental pollution. How to recycle and process them scientifically and efficiently has become an important issue in resource recycling and environmental protection. The recycling and processing of PCBs and integrated circuits typically involves several key steps. First, the discarded components are disassembled and sorted, with reusable parts being screened out; next, metals and non-metallic materials are separated through physical or chemical methods. Precious metals such as gold, silver, and palladium are the focus of recycling, while non-metallic parts like fiberglass and plastic can be used in recycled building materials or fillers. Advanced recycling technologies can also effectively handle hazardous substances, preventing heavy metals like lead and mercury from polluting soil and water sources. At present, many countries and regions have established professional e-waste recycling systems, promoting the resource utilization of PCBs and integrated circuits through policy guidance and technical support. As consumers, we should also actively participate by handing over used electronic products to formal recycling channels, jointly contributing to the development of a green circular economy. Recycling is not only about cherishing resources, but also about taking responsibility for the future. Every scientific processing is a way to reduce the burden on the Earth and contribute to sustainable development.
