The Ocean Cleanup Every year, millions of tons of plastic enter the oceans primarily from rivers. The plastic afloat across the oceans – legacy plastic – isn’t going away on its own. Therefore, solving ocean plastic pollution requires a combination of stemming the inflow and cleaning up what has already accumulated. The Ocean Cleanup, a non-profit organization, develops and scales solutions to rid the world’s oceans of plastic by means of ocean cleanup systems and river interception solutions.
