At 4 a.m., the neon lights of the city finally dimmed, but the "urban mines" on the outskirts of the city were still brightly lit. I stepped onto the creaking wooden floorboards and entered this small factory less than 500 square meters in size. The air was filled with the mixed scents of pine resin, solder, and the burnt smell of plastic. Master Zhou gently placed a discarded computer motherboard on the conveyor belt, as if handing it a ticket to a journeyThe destination of this journey wasn't the landfill, but rebirth. At the end of the conveyor belt, a 2-meter-tall "circuit board recycling device" opened its steel jaws. The rollers first crushed it, then the hammer flattened it. In the blink of an eye, the palm-sized board turned into thumbnail-sized fragments. The magnetic separation drum acted like a meticulous chef, scooping away the iron; the eddy current sorting machine was like a dexterous pick, flicking away the aluminum blocks; and the high-voltage electrostatic field finally performed a "light dance", separating the copper particles from the resin powder. Master Zhou said that the copper purity could reach 99%, directly sent to the smelter, avoiding the "ghost gate" of open-pit mining. I crouched down and picked up the just-separated copper powder. A warm sensation ran through my fingertips, like holding a concentrated bolt of lightning. It had once run on the motherboard, delivering emails and storing photos for us. Now, stripped of its plastic shell, it still shone brightly. At that moment, I suddenly realized: so-called garbage is just resources placed in the wrong place; so-called recycling is letting metals return to the upstream of time, becoming mountains, rivers, and the beating heart of the next mobile phone. Master Zhou handed me a mask, gesturing for me to look up. At the top of the exhaust gas treatment tower, white steam was tinged with a light blue by the night, like a cloud that refused to settle. The equipment was equipped with secondary combustion and activated carbon adsorption. Dioxins were locked in the high-temperature furnace, and heavy metals were firmly captured by the filter bags. The digital screen showed in real time: for every ton of waste boards processed, 3.2 tons of carbon dioxide emissions were reduced, equivalent to the workload of 183 trees in a year. The numbers were cold, but they made my chest feel warm. When I walked out of the factory, it was just getting light. Master Zhou loaded the separated resin powder into black ton bags, preparing to send it to the building materials factory to make manhole covers. He patted the machine, like patting a tired old horse: "Don't underestimate these powders. They can also support the backbone of the city." I looked back. The recycling device glowed a dark red in the morning light, like a giant heart, chewing and digesting the waste circuits, then pumping out fresh metal blood. On my way home, I took out my phone to search for recycling points and booked an appointment for the pickup of my old laptop from the drawer. The screen lit up, and a line of words popped up: "Your device is about to embark on a journey of rebirth." I smiled, as if hearing countless copper particles softly singing in my earphones. Let the sleeping circuits breathe again, let the city's tomorrow open one less mine and add a piece of forest.
