You might not have seen it before: In the suburban regenerated industrial park, rows of silver-gray boxes stand in perfect alignment, like silent sentinels. Conveyor belts slowly feed in used mobile phones and computer motherboards. In an instant, a series of actions—crushing, sorting, desoldering, and gold extraction—are carried out with precision surpassing even the most skilled welders. This is a circuit board recycling device—an "alchemist" in the urban mines. The first time I approached it was to write a report. Through the noise-reducing glass, I saw green substrates being cut into nail-sized fragments. Magnetic separation rollers sucked away iron-like pins; eddy currents like invisible hands flung aluminum chips into silver arcs; finally, copper and gold powders gathered neatly at different outlets, like children lining up after school. At that moment, I suddenly realized: So-called "garbage" is just minerals misplaced in the wrong place. Master Li handed me a small bottle of freshly extracted copper powder, heavy with the luster of rose gold. "This is enough to make a 100-meter-long cable," he said. "If it were buried in a landfill, it would only pollute 500 tons of groundwater." With those words, the last bit of my prejudice that "recycling is just a gimmick for environmental protection" was shattered. The circuit board recycling device isn't a philanthropist—it speaks with data: One ton of waste boards can extract 300 kilograms of copper and 150 grams of gold, along with palladium, tin, and silver... These numbers scroll on the screen like stock market quotations, but far more thrilling—they mean saving one mine and one well. Of course, it also has its temper. Li pointed to the activated carbon layer in the exhaust tower. "If acidic gases escaped, the surrounding vegetable fields would be ruined." Therefore, every recycling device must wear a "mask" and "earplugs": bag dust removal, alkali spraying, and UV decomposition—layered safeguards to ensure that the outgoing air is cleaner than the incoming. Technology and the environment aren't enemies here—they're lovers who complete each other. At dusk, the factory lights come on. The giant rooftop photovoltaic panels, having soaked up sunlight during the day, now feed electricity back to the machines—letting circuit boards be reborn in light and then processed by light, like an energy cycle. I suddenly wondered: If these devices had souls, would they softly hum at night? The lyrics might be: I once lit up your world, now please let me return to my origin, transforming into copper, gold, and the next heartbeat in a motherboard. When I left, Li escorted me to the door. Looking back at the row of steel sentinels, I remembered a saying: True civilization isn't about owning how many appliances, but understanding how to let electricity "return to its roots." The circuit board recycling device is the quietest and most determined ferryman on this journey of return.
