Plastic Industry Awareness of the Ocean Plastics Problem

Fueling Plastics Plastic Industry Awareness of the Ocean Plastics Problem • Scientists became aware of the ocean plastics problem in the 1950s, and understanding of the nature and severity of the problem grew over the next decades. • The major chemical and petroleum companies and industry groups were aware of the ocean plastics problem no later than the 1970s. • Plastics producers have often taken the position that they are only responsible for plastic waste in the form of resin pellets, and that other forms of plastic waste are out of their control.

PLASTICS IN THE ENVIRONMENT The First National On behalf of the plastics industry I would like to comment on several statements Conference on dealing with the environmental effects of plastics in the article “Recycling Solid Waste in Chattanooga” (R. Vredeveld and R. Martin 1973; ABT 35 [2] : 84). Packaging Wastes The authors state, “Plastics are nonbiodegradable; they will remain in the landfills forever.” It is true that most plastics will not biodegrade; but it is that very qual- In addition to questions of ocean ity that makes them especially suitable for sanitary landfills.
