Definitions

  • the invention relates to a process and data management system for the environmentally responsible and verifiable management of the life cycle of plastic so as not to contribute to the accumulation of plastic waste in the general environment.
  • Plastic materials which are produced predominately (over 99%) by the polymerization of fossil hydrocarbons, have become essential to achieving many of centuries’s lifestyle and health objectives. Production and use continue to expand. Production of plastics from fossil hydrocarbons has grown worldwide at an astonishing compound annual growth rate of 8.6% since 1950. The U.S. shale gas boom currently fuels a massive buildout of plastics infrastructure in the United States. Nonetheless, there is a growing dark side to this industry. It involves plastic waste. [0003] Plastics environmental sustainability is the most critical issue facing the plastics industry today. The Plastics Industry Association, in a policy statement, has recognized that it is increasingly necessary to incorporate sustainability in their business plans to retain their "social license to operate”. Sustainability is the main theme of a recent Global Plastics Summit of the Plastics Industry Association.
