What happens after Holiday LEDs receives your lights for recycling?
- The lights are removed from packaging, which is then recycled
- The lights will be processed. Any material that can't be recycled (i.e. loose bulbs)is discarded
- When a substantial number of lights have been collected, they are taken to a third-party recycling facility in Jackson, Mississippi.
- The lights go through a commercial shredder, which chops the lights up into small pieces
- The pieces are then further processed and sorted into separate components that make up lights (pvc, glass, copper)
- Materials are separated and transported to a regional center for further processing. In some cases, the pvc cannot be recycled

We know recycling isn’t always simple, but because many low energy bulbs contain mercury it is important to bring them to a proper recycling facility. So, when it’s time to dispose of your bulbs let us take care of the dirty work. Just bring your old bulbs to your IKEA store, deposit them in the provided bin, and we’ll do the rest! If you prefer to take the bulbs to your local recycling station just remember to handle the bulbs with care.
The (after) life of a light bulb
The different materials in the bulbs are sorted by the recycling facilities and reused when possible. The powder inside low- energy bulbs can be reused in new bulbs, while glass and metal can be used to make fiberglass, which can be found in many things from insulation to boat hulls. Mercury from low-energy bulbs can also be reused in new bulbs.
