As the first meeting of the Intergovernmental Negotiation Committee of the UN Global Treaty to End Plastic Pollution approaches, publications highlight the diverse effects the plastics supply chain has on human health and the environment, particularly the burden on vulnerable communities
Microplastics measured in newborn, infant, and adult feces
Small study assesses polyethylene terephthalate (PET) and polycarbonate (PC) microplastics in human feces; finds PET and PC in all infant stool and in most meconium and adult stool samples; suggests higher exposure of infants than adults
Microplastics: recent insights into human exposure, cellular uptake, cancer metastasis
Researchers report plastic fragments may exacerbate breast cancer metastasis; review summarizes nanoplastic uptake into human cells; studies find occupational microplastics exposure can be reduced by wearing face masks; millions of micro- and nanoplastics are released during 30-second food blending; scientists more worried about microplastic impacts on the environment than humans
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
Novelties of bioplastics: EC’s policy framework and industry updates
European Commission (EC) publishes policy framework on bio-based, biodegradable, and compostable plastics; aims to guide policy, industry, and public; “bioplastics” should not distract from circular economy principles prioritizing reduction, reuse, recycling; 17th annual European Bioplastics conference gives insights into recent bioplastics’ developments; bioplastics production capacities projected to almost triple by 2027
Flame retardants above regulatory limits in some ‘eco-friendly’ baking papers
Study of bio-based food contact articles made of sugarcane bagasse or cellulose wood pulp labelled “natural”, “compostable”, or “biodegradable” finds PFAS and organophosphate esters (OPEs), a type of flame retardant and plasticizer; concentrations highest in baking papers; though purchased in Italy, some OPEs above EU regulatory concentration limit of 0.01 mg/kg
Recent conferences on plastics recycling
Series of recent conferences on both continents focus on discussing challenges and opportunities surrounding plastics recycling, increasing recycled content in products; group of NGOs criticize Circular Plastics Alliance for overlooking hazardous chemicals; predicted lower prices of virgin PET seen as future test of commitment to set sustainability targets
Scientific consensus statement on food contact chemicals and human health
Group of 33 international scientists publish peer-reviewed statement identifying seven specific areas for improvement, urge decision makers to reduce exposure to harmful chemicals present in food packaging and other contact food contact materials
Reusable food packaging and novel coronavirus
UPSTREAM encourages consumers to continue using reusable items with regular washing using soap, expects zero-waste efforts and bring-your-own container programs to further gain momentum after pandemic ends; expanded business models needed to promote sanitizing and reusing packaging
Polystyrene loophole criticized in EU Single Use Plastics Directive
Perspective article highlights extruded polystyrene loophole in the EU’s Single Use Plastics Directive (SUP); SUP bans expanded polystyrene for single-use applications but not structurally similar extruded polystyrene; manufacturers and retailers can switch to alternate material with little net change to hazard or pollution potential
