In the early morning of the city, a truck loaded with used mobile phones drove into the factory. The doors opened, and with a clatter, the chassis, motherboards, and graphics cards poured down like a dark tide. They were once the steeds of the information age, but now they have been sentenced to "death" by time. However, at the end of the conveyor belt, a set of silver-gray circuit board recycling equipment stood silently, like a silent judge, ready to re-read their fate. First to greet the waste boards was the "dismantling officer" — the double-shaft shredder. The alloy steel rollers interlocked and bit each other, and the 20-centimeter-long motherboards were instantly cut into pieces the size of a fingernail. The flying copper foil was like golden snowflakes, and even through the explosion-proof glass, you could still hear the crisp sound of breaking. The fragments then fell into the low-temperature crushing warehouse, where liquid nitrogen plunged the temperature to minus 120 degrees Celsius. The cured resin turned into fine powder in the ball mill, but the copper particles remained resilient, laying the groundwork for subsequent sorting. Next, the fragments entered the "separation officer" — the airflow sorting tower. Ten tiered sieve screens vibrated under the drive of the vibration motor, like ten drums playing at the same time. The heavier copper particles were lifted by the airflow and fell into the bottom collection warehouse; the lighter fiberglass powder was blown to the top and into the resin recovery tank. The copper purity reached 95% at this step, but the equipment was not satisfied. It wanted to make the copper even cleaner. Therefore, the fragments continued to the "electrolysis officer" — the hydrocyclone electrolyzer. The tank was filled with titanium-iridium anodes, and the copper particles swirled and jumped in the acidic electrolyte solution, like a group of gentlemen attending a dinner party, stripping off their "impurities" one by one. Three hours later, a rose-colored copper foil formed on the cathode stainless steel plate, only 0.03 millimeters thick, but enough to re-enter the world of precision circuits. The copper that once carried signals has once again become part of the signal. Finally, the resin powder was sent to the "rebirth officer" — the pyrolysis furnace. At a high temperature of 500 degrees in an oxygen-free environment, the brominated flame retardant decomposed into combustible gas, driving the generator to provide 60% of the electricity for the entire production line; the remaining fiberglass powder was mixed with wood fiber and pressed into outdoor decking boards, which had a subtle elasticity when stepped on, like the earth gently breathing. The waste boards thus completed their cycle, with no waste residue, no wastewater, and no waste gas, only the rustling sound of electricity echoing in the workshop, like a low-key hymn of praise. In the evening, the truck started up again, this time hauling away bundles of cathode copper coils, bags of gray recycled resin, and a quality inspection sheet stamped with the "zero-carbon factory" seal. The setting sun gilded the silver-gray recycling equipment, as if crowning it. The race between humans and electronic waste has never stopped, but on this conveyor belt, technology has given time a chance to overtake: giving every piece of waste board a new life and changing the "death sentence" to "eternal life".
