Plastics in a circular economy: research status, environmental leakage, food safety hazards

Recent studies perform semi-systematic review of published circular economy literature focusing on plastics over past 21 years, develop framework for plastics in circular economy; find Dutch food packaging plastic waste polluting oceans, question effectiveness of recycling; summarize chemical and microbial hazards related to circular food production systems

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

Third meeting of Swiss microplastics researchers

Scientists present and discuss ongoing projects and findings on microplastics; includes research focuses on environmental abundance and health

Scientists emphasize importance for LCAs to consider plastic particle impacts

Review provides understanding of how knowledge gaps on long-term plastic particle fate affect life-cycle assessments (LCAs) and distort policy decisions; exemplifies discussion comparing a fossil-based with a biodegradable plastic; highlights importance of covering plastic particle impacts and its unknowns transparently in LCAs to allow reliable material comparisons and responsible decision making

Behavior and labeling interventions to reduce plastic pollution

Three studies research plastic labeling shortcomings, effectiveness of behavioral interventions; article recommends plastic labels should include sustainability scale, provide regional disposal instructions, and list additives; review considers bigger picture, stakeholder diversity, and several techniques to increase effectiveness of behavioral interventions to reduce single-use plastic consumption; study finds social media does not affect consumer’s intentions to recycle plastics

WWF: marine plastic pollution irreversible, strategies needed beyond recycling

World Wildlife Fund (WWF) publishes principles for chemical recycling to avoid harming human health or goals for circular economy; should not compete with mechanical recycling, need transparency about resource consumption; prioritize reduction, reuse over recycling; WWF and Alfred Wegener Institute report on plastics’ impacts on oceans; plastic contamination is permanent; at least 2144 species affected, 99.8% of seabird species will eat plastics by 2050

UV-328, PFCAs, chlorinated paraffins move closer to global restrictions

17th meeting of the Stockholm Convention’s Persistent Organic Pollutants Review Committee (POPRC) considers scientific evidence, agrees to move all substances onto next step in review process; long-chain perfluorocarboxylic acids (PFCAs), medium-chain chlorinated paraffins, and UV-328 all known to have been used in food packaging

Scientists warn over-production of chemicals altering planetary systems

Peer-reviewed study finds pollution from synthetic chemical production and plastics is now altering planetary systems vital to human survival; recommends implementing cap on chemical production and release similar to greenhouse gases

Ghana publishes roadmap for ‘radical’ reduction of plastic pollution

Ghana National Plastic Action Partnership publishes roadmap to reduce plastic use and pollution in the country; includes 11 case studies of projects already underway; outlines strategies for both public and private institutions to contribute to the vision

Report summarizes US role in marine plastic pollution

US National Academies of Sciences, Engineering, and Medicine publishes report outlining US contribution and response to global ocean plastic waste; identifies data gaps and recommendations for US policy action across the supply chain; says US should ‘substantially’ reduce waste generation
