Marine debris is a big problem for the plastics industry. According to the most frequently cited research, between 4.8 million and 12.7 million metric tons of plastic waste entered the ocean in 2010. The future looks a lot worse. Population growth and improved standards of living around the world will mean millions more tons of plastic marine debris. Plastics processors and suppliers need to help solve the problem. In fact, some major companies already are involved. Amcor Ltd. and Berry Global Inc. were among the presenters at the American Chemistry Council's Marine Debris Dialogue, held June 19-20 in Newport, R.I.
