Recent studies explore the presence and migration of diverse synthetic antioxidants in Chinese food contact materials (FCMs); both phosphite antioxidants and synthetic phenolic antioxidants are commonly found; typically, FCMs contain several mg of synthetic antioxidants per kg FCM; several of the commonly found antioxidants are suspected endocrine disruptors
Japan preparing food contact material regulation for June 2025 enforcement deadline
Japan finalizes structure of positive list for synthetic polymer containing utensils, containers, and packaging for food contact; lists 21 approved polymer types and 827 approved additives; consultation on additional additives ongoing; positive list system must be fully implemented by manufacturers by June 2025
Report questions viability and environmental benefits of plastic chemical recycling
Report commissioned by the Swiss Federal Office for the Environment (FOEN) reviews chemical recycling of plastic waste; finds the technical feasibility, environmental benefits, and economic viability of the technology are not sufficiently demonstrated; excessive subsidies or investments may lock-in environmentally unfavorable processes and infrastructure
Mixed reactions as UN concludes fourth round of INC plastics treaty negotiations
Fourth round of negotiations for a new global instrument on plastic pollution took place in Ottawa, Canada from April 23 – 29, 2024; member states agree on intersessional work to be carried out on financial mechanisms and chemicals of concern ahead of upcoming final session; no agreement on reducing primary plastic production; concerns raised over industry lobbyists outnumbering scientists and many national delegations; final INC-5 meeting set to take place in Busan, Republic of Korea on November 25 – December 1, 2024
Scientists propose life-cycle-based criteria for polymers of concern
Scientists develop holistic conceptual framework to determine polymers of concern; criteria go beyond intrinsic properties and take life cycle considerations into account; packaging particularly problematic regarding environmental leakage; scientists are calling for swift action on polymers of concern despite some data gaps
Plastic recycling
The dossier article addresses plastic recycling processes and legal requirements that have to be fulfilled for recycled plastic to be used in FCMs. Further, market and recycling data, as well as safety issues, are discussed. A special focus is given to the recycling of polyethylene terephthalate (PET).
The chemical and waste footprint of food delivery in China
Study uses online food delivery sales data from nearly 200 Chinese cities, combined with packaging samples from 18 of those cities to model packaging waste generation and chemical exposure from waste incineration; some degradation products with higher concentrations than intentionally added parent product; over 50 tons of the targeted additives likely released into the atmosphere from Chinese waste incinerators
