Plastic Bank encourages recycling entrepreneurs to collect plastic bottle waste on beaches and take them to Plastic Bank collection points. Plastic Bank incentivizes collectors to gather the trash and bring it in for recycling. Plastic Bank recycles the material into "social plastic," which it then resells at a premium to environmentally aware-partner businesses like Henkel and Norton Point Sunglasses, which in turn craft it into recycled consumer goods or 3D printed bricks for building houses or for use in packaging via consumer product companies, each branded with the "social plastic" message. Most importantly, it keeps plastic out of the ocean.
