Scientists review three main routes for polyhydroxyalkanoates (PHA) production, including microbiological, enzymatic, chemical; microbiological and chemical routes most favorable for scaling-up; remaining high costs compared to fossil-based plastics necessitate search for cheaper feedstocks, optimization of production efficiencies
Phthalates: impact on leiomyoma growth and mixture risk
Study identifies mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) exposure as high-risk factor for leiomyoma growth on epidemiological and mechanistic level; European biomonitoring of five reprotoxic phthalates demonstrates necessity to integrate mixture risk assessment into regulatory practice; targeted analysis shows migration of five phthalates from polypropylene food packaging
‘The trouble with plastics’
Special issue of peer-reviewed journal Birth Defects Research presents a collection of articles on plastics’ effects on human health, with a particular focus on early development
Measures to limit chemical migration from recycled paperboard
Review identifies and discusses three approaches to limit chemical migration from recycled paperboard to make it acceptable for food applications; considers internal bags with an incorporated barrier, barrier layers, and functional sorbents added to the board; study on migration from paper cups identifies exposures to vanadium and fluoride

Scientists propose and apply NIAS identification approaches
Review provides guidance to select analytical technique for non-intentionally added substances (NIAS) identification and quantification in food contact materials (FCMs); scientific studies analyze NIAS migrating from FCMs; develop model to predict collision cross-section values to identify NIAS in FCMs; detect polyethylene terephthalate (PET) oligomers in post-mortem blood samples
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
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
Plastics identified as source of legal liability
Minderoo Foundation finds liabilities from the health and environmental effects of microplastics and plastic-related chemicals to be worth more than $20 billion in the US by 2030; potentially up to $100 billion in liabilities expected by 2030 with the number expected to increase in the future; article published by the American Bar Association focuses on potential corporate liabilities from micro- and nanoplastics in particular
Researchers detect microplastics in human semen and heart
Four recent studies assess microplastics: in human semen, heart, from baby food containers, and suitability of in vitro models to investigate human health effects; find microplastics in six out of ten semen samples, find impacts on semen quality; samples from cardiac surgery patients contain microplastics in heart and surrounding tissue; billions of nano- and microplastics released from plastic baby food containers; outline challenges and recommendation of studying plastic particles in vitro
