Several recent reviews examine the value chain of biobased polymers; discuss clarification of terms such as biobased, degradable, biodegradable, and compostable; define “biotechnological recycling (bio-recycling)” as the use of enzymes and microorganisms in a technological setting to biodegrade polymers; three biodegradable polymers assessed in marine field trials
Reverse causation bias in PFOA studies
Scientists suggest increased perfluorooctanoic acid (PFOA) blood levels are consequence of early menopause and kidney disease, not cause
Two articles review oligomers and other chemicals migrating from bio-based products
Research study compares different techniques for oligomer detection and finds polyester oligomers migrate from biopolymers; book chapter discusses catalysts, volatile organic compounds, and additives in bio-based products, including their migration and safety
New method for analysis of BPA in recycled food contact paper
Spanish study shows new and fast method allows for an accurate determination of bisphenol-type compounds and measured BPA in all analyzed recycled materials.
Studies assess composition and safety of chemicals in recycled HDPE
Scientists analyze volatile compounds in recycled high-density polyethylene (HDPE); detect 53 chemicals in two post-consumer HDPE milk bottles including plastic additives and non-intentionally added substances (NIAS); risk assessment shows samples do not comply with plastic food packaging regulation; report re-granulation process in mechanical recycling to remove most but not all odor and volatile organic compounds
Australian government to start regulating packaging
Australian environment ministers agree to “address the use of harmful chemicals in food packaging,” create packaging design standards and targets, harmonize curbside recycling programs; details forthcoming
EFSA: Updated risk assessment of five phthalates
European Food Safety Authority publishes updated risk assessment for the phthalates DBP, BBP, DEHP, DINP, DIDP; retains developed group and individual tolerable daily intake limits; finds no current public health concern but cautions that values set are temporary due to uncertainties
US state policies on PFAS in food contact, Q3 and Q4 2023
Maine and Minnesota consult on draft policies concerning bans or reporting requirements on per- and polyfluoroalkyl substances (PFAS) in food contact materials and articles; California Attorney General warns companies of penalties for selling or failing to disclose PFAS-containing food packaging and cookware; Nevada governor vetoes PFAS bill, state senator plans to reintroduce bill in 2024
Migration from printing inks in multilayer FCMs
Scientists analyze printing inks migration in multilayer materials; use of overprint varnish or placement under PET layer decreases migration of ink components but may introduce other migrants
Migration from aged polycarbonate plastics
Scientists examine influence of ageing on the migration of oligomers and coloring agents from polycarbonate tableware; higher migration of degradation products from older and damaged plastics, colorants from newer products
