Plastic production, consumption and waste is increasing and affecting marine, freshwater and terrestrial ecosystems, and contributing to greenhouse gas (GHG) and hazardous chemical emissions.

In the traditional economy goods are made, used, and then discarded. But in a circular economy products and packaging get a second (or third or fourth) chance at usefulness. The goal of the circular ...
