This Oceanworks Guaranteed HDPE (High Density Polyethylene) is sourced from Europe and comes in the form of black pellets. It is ocean plastic recovered from fishing nets, trawls, and ropes. This material is the result of an interception program in place across various ports to reimburse fisherman for retired fishing gear. It is guaranteed to have been harvested from a near shore location, one of the five types of locations where ocean plastic is collected worldwide, which means that it is material in the shallow areas of ocean near the shore line.
