Neither the author or previous posters mentioned an obvious means of reducing the plastic waste problem, namely, use less of it, especially throwaway plastics.
Some of the plastics are converted to diesel fuel and home heating oil. I consume some of the diesel oil in my Unimog. A percentage of our home heating oil is from that source too.
The plastic that goes about 10 miles south is shredded and converted into septic system leach field components of the Presby Maze.
