Since July 2021, when Maine passed the nation's first extended producer responsiblity ("EPR") packaging law, four other states (Colorado, Oregon, California, and Maryland) have enacted EPR packaging laws. For brevity, we refer to these laws as packaging laws, but other non-packaging materials are covered under these laws (varying from state to state) including certain paper products and foodservice ware -- with plastics as a targeted material in all these programs.
