In Guangdong there’s a small town that specializes in recycling Christmas lights. They chip the lights into mm sized bits, and then use a modified sluicebox (a vibrating inclined water table) to separate the brass and copper from the glass, plastic and rubber by density. All of these bits are then re-used in other products. The entire process would be uneconomical in the US, because our labor is too expensive, and there’s no market here for plastic scrap.
