We use TerraCycle. Once we’ve collected enough pencils, we ship them to TerraCycle using their Zero Waste Boxes. The costs associated are not with the physical box itself, but rather the service provided. As this service is completely independent of their free recycling programs, there are no brand partners who sponsor the service. The cost includes the shipping to us and back to them as well as the recycling process of the pencils. TerraCycle is a private, for-profit company.
