Our ice packs are made of recyclable high-density polyethylene (HDPE), which contains either a water or gel-based coolant. It’s worth checking your local guidelines, but these can often be recycled once the HDPE shell after draining the coolant. Ice packs can also be reused many times over, so long as they’ve not come into contact with toxic materials. Large quantities of ice packs you've accumulated over time can be returned to us as we’re happy to arrange collection of any pallets of ice packs, which we will then dispose of ourselves. Please contact us using the Abcam order email address to arrange for the collection.
