From Green LA Girl:
Recycle your old holiday LED lights by packing them up along with your name and email address to:
Attn: Recycling Program
118 Rosehill Dr., Suite 1
Jackson, MI 49202
According to the HolidatLEDs.com website, the recycling process goes as follows:
When we receive your lights for recycling we will remove them from the package and recycle the box. The lights will be processed and any material that cannot be recycled (i.e. loose bulbs)is discarded. Once we have collected a substantial number of sets we take them to a 3rd party recycling facility located in Jackson, MI. The recycling company puts the lights through a commercial shredder, which chops the lights up into little pieces. The pieces are then further processed and sorted into the various components that make up the lights (pvc, glass, copper.) The materials are separated and transported to a region center for further processing.
