How does a recycling plant sort everything?

What actually happens after your recycling bin gets emptied? Inside a modern recycling plant, one enormous pile of cardboard, plastic bottles, steel cans, aluminum cans, and other materials has to be separated back into individual streams. In this video, we follow that process from start to finish and explain how recycling plants use screens, magnets, optical sensors, air jets, eddy-current separators, and quality-control systems to sort mixed recyclables. The surprising part? There isn't one machine that identifies everything. Instead, the plant turns one difficult sorting problem into a series of much simpler ones—separating materials by size, shape, magnetism, and how they react to light. See how a chaotic pile of recycling becomes separate materials ready to be processed and used again. #Recycling #HowItWorks #Engineering #Technology #Explained
