U.S. retailer Target asks suppliers to provide more information on chemicals to fulfil its goals on ingredient transparency and product reformulation
Non-target screening of silicone rubber extracts
Scientists perform non-target screening of compounds extracted from infant silicone teats; identify 140 compounds in 12 categories; more than a third of substances need safety evaluation
Plastic recycling: company commitments and chemical safety challenges
Scientists report most large companies commit to reducing plastic pollution but focus on recycling; extrusion of recycled materials and legacy compounds in recycled materials as safety challenge; some substances increase others decrease with the increase in recycled content in polyethylene terephthalate (PET) bottles; tentatively identify 212 volatile chemicals in 57 different recycled PET flakes available in China; present migration model to characterize the exposure and risk of PET oligomers
Chemical characterization of post-consumer and recycled plastics
Scientists perform target and non-target screening of recycled plastics and provide recommendations on methods; detect >280 organic chemicals and metals in 21 plastic flakes and pellets used in recycling; analyze several recycled polymers and find polyethylene terephthalate (PET) the only one currently complying with European circular economy requirements; compare analytical methods to assess the chemical composition of recyclates giving their strenghts and limitations
New research on chemical migration from plastic, paper, can coating, and reusables
Recent reports investigate whitening agents’ migration from disposable plastic containers; characterize 153 chemicals migrating from paper packaging and show estimated dietary exposure for children to per- and polyfluorinated alkyl substances (PFAS) exceed safety threshold; detect brominated flame retardants in repeat-use food contact articles; review metal can coating literature concerning coatings types, chemical migrants, detection methods, dietary exposure, and regulatory
Studies investigate circular economy barriers, consumer perceptions
Recent set of articles in peer-reviewed scientific journals review current barriers in flexible plastics to achieving circular economy, recommends regulatory policies be tailored to individual steps in supply chain; consumers easily confused by plastic waste management system, recycling processes, biodegradability claims; researchers instead propose food system shift towards decentralization, shorter supply chains
Measuring plastic particles released from food packaging and in human lungs
Scientists investigate plastic particles released from store-bought food packaging as well as human and mice health impacts of exposure; report single-use plastic products release >1012 nano-sized particles during use; find microplastics to suppress lysosomal activity in mouse macrophages; first detection of microplastics within human lung tissue samples; in vitro neurotoxicity study finds microplastics negatively impact human forebrain organoid development
Scientists evaluate inhaled microplastics
Report microplastics occur in lower airways of European citizens with the majority being fibers; evaluate microplastics indoor and outdoor exposure sources; work out established particle domains and paradigms can help predict toxicity of inhaled microplastic particles
Stakeholders discuss waste management challenges of plastics
Publications from government, academia, civil society organizations, and consultancies paint problematic picture of a circular plastics economy; plastic packaging waste per person found to increase over last decade; low percentage of plastic produced is effectively recycled; pyrolysis (a type of chemical recycling) of plastics produces 9x more emissions than mechanical recycling; “biodegradable” and “compostable” plastics found to not break down in home compost systems
