In 1993, Matson began a pilot program with the Center for Marine Conservation (now the Ocean Conservancy) to address marine debris generated from ocean-going vessels. Dedicated “greentainers” were placed on each vessel in the Matson fleet. All solid waste, except food scraps, is placed in this container and prohibited from being discharged overboard. The greentainer is unloaded at a shoreside facility and the contents sent to recycling, waste-to-energy, or other acceptable disposal facilities. Matson was the first container vessel company to initiate a zero discharge policy and our efforts were recognized by the National Research Council of the National Academies in their publication Tackling Marine Debris in the 21st Century.
