This is the second in a series evaluating the challenges in single-use food packaging waste.
[pullquote]See our list of key chemicals of concern in food packaging.[/pullquote]In the late 1980s, the Council of Northeast Governors (CONEG) was concerned that heavy metals in packaging would accumulate in recycled materials to levels that presented serious health concerns. The organization drafted model legislation that prohibited the intentional addition of mercury, lead, cadmium, and hexavalent chromium to any component of packaging, including inks. It also set a 100 parts-per-million limit on the total amount of these four heavy metals. To ensure compliance, companies making packaging materials had to provide certificates of compliance to downstream purchasers and report compliance to the states.
CONEG also established the Toxics in Packaging Clearinghouse to maintain the model legislation, coordinate implementation of state legislation, and serve as a resource for companies seeking compliance information. The Council’s hypothesis: protecting virgin material from contamination will improve the recyclability of post-consumer materials and protect public health.
Over the years, 19 states have adopted a variation of the model legislation. In 2018, the State of Washington took an unprecedented step of expanding its version of the legislation from heavy metals to include per- and poly-fluorinated alkyl substances (PFAS). PFAS are bioaccumulating, persistent chemicals and are associated with an array of health problems including endocrine disruption and children’s developmental harm. The State was concerned that paper and cardboard food packaging treated with these chemicals may be contaminating composting and paper recycling processes post-consumer.
