In our daily lives, from smartphones and computers to household appliances, almost all electronic devices rely on two core components: printed circuit boards (PCBs) and integrated circuits (ICs).They are the "brains" and "nervous systems" of electronic products.However, when these devices become obsolete, these sophisticated components become troublesome electronic waste. But you may not know that these seemingly useless waste materials are actually "urban mines" rich in resources. I. Why Specialize in Recycling and Processing PCBs and ICs? 1. Huge Resource Value: PCBs and integrated circuits contain precious metals such as gold, silver, palladium, and copper, with concentrations far exceeding those in primary ores.Efficient recycling is equivalent to mining a high-grade mine. 2. Serious Environmental Hazards: If discarded or incinerated indiscriminately, harmful substances such as lead, mercury, cadmium, and brominated flame retardants in PCBs will seep into soil and groundwater, seriously polluting the environment and directly threatening ecology and human health. 3. Data Security Requirements: Especially for storage-type chips, improper processing may lead to the leakage of sensitive data such as personal information and trade secrets. II. What Is the Professional Recycling Process? Professional recycling is a complex and technology-intensive process aimed at maximizing resource recovery and minimizing environmental risks. 1. Disassembling and Sorting: First, disassemble the discarded electronic products manually or mechanically to separate PCBs and various integrated circuits.Then, sort them by type (such as motherboards, memory modules, chipsets). 2. Physical Crushing: Use specialized crushing equipment to crush large PCBs into small pieces, preparing for subsequent separation. 3. Sorting and Purification: * Magnetic Sorting: Use magnetic force to separate ferromagnetic metals. * Eddy Current Sorting: Separate non-ferrous metals (such as copper and aluminum). * Electrostatic Sorting: Further separate metals and non-metals (such as fiberglass and epoxy resin). 4. Metallurgical Recovery (Core Process): * Heat Treatment: Remove organic matter through high-temperature incineration to enrich precious metals. * Hydrometallurgy: Use chemical solvents such as acids and alkalis to dissolve precious metals from fragments, then extract high-purity gold, silver, palladium, etc. through displacement and electrolysis. * Pyrometallurgy: In high-temperature furnaces, metals are melted and separated, with precious metals enriched in specific alloys. 5. Harmless Treatment: Strictly handle waste acids, alkalis, gases, and wastewater generated during the recycling process to ensure compliant discharge. Residual non-metallic materials can also be used as building material fillers, achieving full-process greenness. III. What Can We Do Individually? Electronic products are updated and replaced at a rapid pace, and it is everyone's responsibility to properly handle waste electronics. * Refuse indiscriminate discarding: Never mix discarded computers, mobile phones, etc. with ordinary household waste. * Choose formal channels: Hand over electronic waste to qualified recyclers, production enterprises, or participate in official "trade-in for new" activities. * Raise recycling awareness: Support and purchase products made from recycled materials to jointly promote the development of a circular economy. Conclusion The professional recycling and processing of PCBs and integrated circuits is not only a "reduction of resources", but also a "protection of the fragile environment".This is not only the responsibility of recycling companies, but also requires the joint efforts of the entire supply chain, from manufacturers to consumers.Let every discarded circuit board end its mission as a source of pollution and begin a new life as a treasure trove of resources, together safeguarding our only green Earth.
