Our free recycling program with TerraCycle is currently available to anyone living in the continental US. Simply sign up through TerraCycle to receive a free, zero-waste, pre-paid envelope and then fill it with your empty, cleaned out Mad Hippie plastic packaging (bottles, pumps, plastic seals, sample packets, sprayers, and caps) and drop in the nearest USPS mailbox! Please fill the envelope with as much Mad Hippie packaging as you can fit to further reduce the carbon footprint (ideally several months worth of product packaging in one envelope).
