OPERATION CLEAN SWEEP® (OCS) is an international program designed to prevent plastic pellet loss and the potential introduction of pellets to the marine environment where they create both a litter problem and a threat to marine and wildlife. The essence of OCS is to help each segment of the plastics industry. This includes resin producers, transporters, bulk terminal operators, and plastics processors. The focus to implement good housekeeping and pellet containment practices will aid at achieving zero pellet loss.
