Chemicals in compostable packaging materials: presence, persistence, and circular chemistry

The presence of per- and polyfluoroalkyl substances (PFAS) has been reported in biodegradable and compostable food-contact materials (FCMs). Leveraged to support the functional properties of these articles, they have become an unquantified source of PFAS contamination in organics waste recycling. PFAS in biodegradable and compostable FCMs are a concern due to their persistence, toxicity and bioaccumulative properties and have the potential to impact a variety of sensitive environmental receptors, including those which may be exposed to any compost generated. This research will use a suite of analytical techniques to investigate PFAS in Australia's waste compostable packaging, assess what happens to them during the composting process, and determine what impacts they might have to the environment.
