From Christmas tree lights to slippers, how tree lights are recycled

Most of us have seen glass and plastic being recycled however recycling of consumer goods made with multiple materials can be much more challenging. In the past Christmas tree lights have been burnt to obtain the copper but this releases a slew of toxic chemicals into the air from the burning plastic. A better solution has been found by a Chinese recycling company that specializes in recycling all the material from light strings once they have served out their time on trees, roofs and gardens.
