Under the rapid development of modern electronic technology, the amount of printed circuit boards (PCBs) and integrated circuits (ICs) being discarded is increasing year by year, as these components form the core of electronic devices. These electronic waste not only contains valuable metal resources such as gold, silver, and copper, but also potentially harmful substances like lead, mercury, and cadmium. Therefore, how to efficiently and environmentally recycle PCBs and ICs has become an important global concern. The recycling of PCBs and ICs typically involves several key steps. First, the dismantling of discarded electronic devices is carried out manually or mechanically to separate the usable PCBs and IC components. Next, physical methods (such as crushing and sorting) are used to initially separate metals from non-metallic materials. Then, precious and non-ferrous metals are extracted through chemical processing (e.g., acid leaching and electrolysis) or high-temperature smelting techniques. Finally, the remaining non-metallic materials (such as epoxy resins and fiberglass) are treated harmlessly or recycled to minimize environmental impact. However, this process faces many challenges. PCBs and ICs are structurally complex, contain diverse components, and harbor a large number of harmful substances. Improper handling can easily lead to soil, water, and air pollution. At the same time, existing recycling technologies are costly, and some small and medium-sized enterprises still adopt crude processing methods (such as direct incineration or landfilling), further exacerbating environmental risks. Additionally, public awareness of electronic waste recycling is insufficient, resulting in a large number of PCBs and ICs not being properly handled. To address these challenges, governments, enterprises, and society need to work together. On the one hand, we should strengthen regulatory frameworks and promote the extended producer responsibility system to encourage electronic product manufacturers to participate in recycling. On the other hand, we need to continuously develop innovative technologies such as bio-metallurgy and green chemical solvents to improve recycling efficiency and reduce environmental burdens. At the same time, we should raise public awareness through education and establish convenient recycling channels to guide consumers to properly dispose of electronic waste. In summary, the recycling of PCBs and ICs is a systematic project that integrates technology, environmental protection, and economics. Only through collaboration and innovation across society can we achieve the resource and harmless management of electronic waste and contribute to sustainable development.
