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
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
Food Packaging Forum director comments on report outlining food packaging opportunities for the upcoming UN Food Systems Summit; suggests including plastic pollution as a food systems issue for discussion
India implements extended producer responsibility (EPR) program for plastic packaging, effective immediately; recycling targets for plastic producers, importers, and brand-owners start at 25% and progressively get stricter; Indian standards authority strengthens regulations for recycled plastic in food contact after receiving pushback
In the afternoon of the Food Packaging Forum’s 11th annual workshop, speakers shared businesses experiences on the path towards more safe and sustainable food packaging; five talks and one panel discussion present opportunities, challenges, and case studies; representatives from several large international businesses shared approaches their organizations use to respond to safety and sustainability challenges; reusable packaging founders discuss the unique issues of changing the food packaging field
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
Study proposes a preliminary physiologically-based toxicokinetic (PBTK) model for micro- and nanoplastics (MNPs); polymer type, size, shape, surface chemistry, surface biofilms, and biocorona determine toxicokinetic rates; models for engineered nanoparticles are not appropriate due to heterogeneity of MNPs; uptake via inhalation and effects of absorbed chemicals need more investigation
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
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
Study provides an in-depth look at microplastics in the male reproductive system, analyzes human and mouse samples to chart concentrations and polymer types; finds microplastics in all human testes samples and majority of semen samples; larger plastic particles may get trapped in testis, leading to higher concentrations; identifies correlation between urbanization, home-cooked meals, and body scrub used to microplastics concentration
