Around 1990, driven by a concern to keep heavy metals out of recycled products, many states adopted laws prohibiting the intentional addition of arsenic, cadmium, lead, and mercury to packaging and limited their total concentration to 100 parts per million. Manufacturers and suppliers of packaging and packaging components in these states were also both required to furnish a Certificate of Compliance to the packaging purchaser and provide a copy to the state and the public upon request. The Toxics in Packaging Clearinghouse currently reports that 19 states have adopted this type of legislation.
Out of concern about consumer’s health and contamination of compost, on February 28, 2018, Washington State extended its heavy metal packaging law in a groundbreaking way. The legislature passed HB-2658 banning the intentional use of “perfluoroalkyl and polyfluoroalkyl substances” (PFAS) in food packaging made from plant fibers, pending a determination by the Washington Department of Ecology that safer alternatives are available. The law defines PFAS as “a class of fluorinated organic chemicals containing at least one fully fluorinated carbon atom.”
