Minutes from recent meetings of the European Food Safety Authority (EFSA) CEP panel and working groups on bisphenol A (BPA), food contact materials (FCMs), recycling plastics, and phthalates published; groups continue discussions and revisions of draft opinions; new working group on re-evaluation of phthalates and structurally similar substances in FCMs launched
State of the science and regulation – microplastics and nanoplastics
California State Policy Evidence Consortium and DG Environment publish reports on the abundance, health effects and (potential) regulations on microplastics and nanoplastics, respectively; first finds most regulations come from California or EU and concern banning microbeads or mandating more research; second argues against a lower size cutoff of nanoplastics since the smaller the plastic particles, the more likely they can cross biological membranes
Action and inaction on PFAS in the US federal government
Earthjustice files petition asking US Environmental Protection Agency (EPA) to revoke approval of 600 per- and polyfluoroalkyl substances (PFAS) allowed on the market under exemptions of the Toxic Substances Control Act; represents about half the number of PFAS on the market; EPA extends reach of guidelines for federal purchasing of PFAS-free products; Food and Drug Administration funding bill stripped of reform amendments including federal ban on PFAS in food packaging
Study detects DNA-reactive, mutagenic substances in recycled PE, PP, and PS
119 plastic samples including polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET) tested for mutagenicity; no DNA-reactive, mutagenic substances in PET but in 51 of the other samples, making them unsafe, especially for food contact applications; recycling process identified as source; dataset of over 600 organic chemicals in recycled high-density PE pellets published
Properties of rPET-containing bottles
Scientists examine effects of recycled PET (rPET) on bottles’ properties, propose generic model to calculate acceptable rPET content for different scenarios; bottles from mono-collection systems have less particle contamination, more favorable optical properties, lower accumulation of contaminants, and therefore recommended to allow higher recycled content
Behavior and labeling interventions to reduce plastic pollution
Three studies research plastic labeling shortcomings, effectiveness of behavioral interventions; article recommends plastic labels should include sustainability scale, provide regional disposal instructions, and list additives; review considers bigger picture, stakeholder diversity, and several techniques to increase effectiveness of behavioral interventions to reduce single-use plastic consumption; study finds social media does not affect consumer’s intentions to recycle plastics
EFSA stakeholder workshop on small particles and nanoparticles in food
European Food Safety Authority (EFSA) presentations provide guidance on small particles in food and feed applications (i) evaluating the potential presence of particles in ‘conventional’ materials and (ii) how to perform nano-specific risk assessment; stakeholders share experience and discuss practices to implement guidance cost-effectively
UV-328 listed as POP under the Stockholm Convention
11th meeting of the Conference of the Parties to the Stockholm Convention lists UV absorber as Persistent Organic Pollutant (POP); first non-halogenated POP under the Convention; also listing of flame retardant dechlorane plus and pesticide methoxychlor in Annex A
Associations report European packaging recycling rates
Industry associations report recycling rates of packaging materials in Europe; average collection rate of glass bottles and jars hit 80% in 2020; paper packaging recycling over 80%; paper recycling rates close to theoretical maximum; plastic recycling has not increased despite increased demand by beverage companies; two-thirds of plastic-packaging pledges in Europe failed, supporting the change away from single-use likely necessary
Hazard prioritization of printing inks and adhesives substances
Scientific study performs hazard prioritization on chemicals in printing inks and adhesives applied to plastic food packaging; uses publicly available “substances of concern” lists and an in silico tool; identifies 636 high and 1024 medium priority substances of which 696 ranked as “very high priority substances” by experts
