Three recent studies explore the chemical safety of bio-based food contact materials (FCMs); current analytical methods fail to detect all hazardous substances in bio-based FCMs, in vitro bioassays are suitable addition; Dutch "eco-friendly" FCMs often contain non-biodegradable components and substances like pesticides and PFAS; migration of allergens found

The production of food contact materials (FCMs) from plant biomass is popular because renewable feedstocks can help to reduce harmful CO2 emissions to the atmosphere. Other environmental impacts, such as land use, can partially be reduced using waste biomass (FPF reported and here). FCMs made from renewable feedstocks include bio-based plastics, paper & cardboard, or composite materials with plant fibers.  Because some of these materials are relatively new and undergoing constant innovation, the chemical composition and health concerns are not well known. Three recent studies investigated sustainability claims and safety aspects of plant-based or plant-containing FCMs. ....
