In our digital age, printed circuit boards (PCBs) and integrated circuits (ICs) are the "brains" and "neural networks" of almost all electronic devices. They can be found everywhere, from smartphones and computers to home appliances and automobiles. However, with the accelerated replacement of products, a large number of discarded PCB boards and ICs have emerged. They are not only dangerous electronic waste, but also "urban minerals" rich in resources. I. Why Must They Be Professionally Recycled? — Hidden Dual Attributes * Harmfulness: Discarded PCB boards and ICs contain various hazardous substances such as lead, mercury, cadmium, and brominated flame retardants. If they are randomly discarded or simply incinerated, these toxic components will seep into the soil and groundwater or be released into the air, posing a serious threat to the environment and human health. * Resourcefulness: On the other hand, they are veritable "concentrates". Their internal components are rich in precious metals such as gold, silver, palladium, and copper, with a grade far higher than that of natural ores. Efficiently recycling these resources can not only reduce the exploitation of primary minerals, but also create huge economic value. II. The Core Process of Recycling — Technology-Enabled, Turning Waste into Treasure Professional recycling is a complex and technology-intensive process aimed at safely and efficiently achieving resource regeneration: 1. Disassembly and Classification: First, the entire device is manually or mechanically disassembled to separate PCB boards and various IC chips. Meticulous classification is the foundation for improving the efficiency and purity of subsequent recycling. 2. Physical Crushing and Sorting: Using specialized crushing equipment, PCB boards are crushed into small pieces, then preliminarily separated into metal and non-metal (mainly resin fibers) components through techniques such as magnetic separation, eddy current separation, and electrostatic separation. 3. Metallurgical Extraction (Core Technology): This is the key step in recovering precious metals. * Pyrometallurgy: Through high-temperature melting, metals are separated from impurities and concentrated in alloys, which are then further refined and purified. This method has high processing capacity but high energy consumption, requiring strict control of exhaust gas emissions. * Hydrometallurgy: Using chemical solvents (such as acids and cyanides) to dissolve metals from crushed materials, then recovering pure metals through methods such as precipitation, extraction, and electrolysis. This method has high recovery rates but may generate wastewater, which needs to be properly handled. 4. Advanced Processing and Reuse: The extracted high-purity metals can be reused as industrial raw materials in the production line; the separated non-metallic materials can also be used in the manufacture of building materials, roadbeds, etc., achieving full-component resource utilization. III. Our Responsibilities and Future The recycling of PCB boards and integrated circuits is not only an inevitable requirement for environmental protection, but also an important practice of circular economy. As consumers, we should choose formal recycling channels to avoid random discarding; as enterprises, we should fulfill our obligations of extended producer responsibility (EPR) and consider recyclability from the design stage of products. Let every discarded circuit board find its green "destination" and complete the transformation from "electronic waste" to "urban treasure". This requires our joint efforts to reduce the burden on the earth and create value for the future.
