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

First proposals put forward for global treaty to end plastic pollution

Countries are submitting proposals to the UN Environment Program to guide Plastics Treaty development; US proposes treaty focus on downstream effects – reuse and recycling; proposal from 40-nation ‘high ambition coalition’ proposes setting up limits on polymer production, eliminating certain polymers and products; over 60 proposals received so far; stakeholder registration is open for the next negotiating meeting for the Plastics Treaty in Paris, France in May 2023

Colombia launches Plastics Pact while previous Pacts struggle with 2025 targets

Colombia Plastics Pact launches; the second Latin American country to join the Plastics Pact program; reports show UK and US Plastics Pacts are unlikely to hit 2025 goals as total plastic use keeps increasing

EFSA CEP Panel updates from October 2022 to February 2023

Minutes available from recent meetings of the working groups on food contact materials (FCMs), bisphenol A (BPA), and recycling plastics, within the European Food Safety Authority’s (EFSA’s) Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel); no further meeting of the BPA working group planned; specific migration limit (SML) for styrene in FCMs upcoming

Studies assess composition and safety of chemicals in recycled HDPE

Scientists analyze volatile compounds in recycled high-density polyethylene (HDPE); detect 53 chemicals in two post-consumer HDPE milk bottles including plastic additives and non-intentionally added substances (NIAS); risk assessment shows samples do not comply with plastic food packaging regulation; report re-granulation process in mechanical recycling to remove most but not all odor and volatile organic compounds

Studies assess PFAS, OPEs, and plasticizers in paper & board

Review summarizes per- and polyfluoroalkyl substances (PFAS) migration from paper food packaging into food and food simulants and identifies dietary exposure of PFAS as potential human health risk; study highlights need to further evaluate organophosphate esters (OPEs) and prohibited PFAS in paper and aluminum foil food packaging; scientists analyze and recommend extraction method to assess plasticizers in recycled paperboard

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

Model indicates 70% reduction of microplastics by 2050 possible

Material flow analysis on microplastics provides recommendations for reducing microplastics in the Netherlands; effective measures include extension of deposit schemes on returnable plastics, research in improved recycling technologies, and “R-strategies”

Corporate plastic commitments not expected to meet 2025 targets

Ellen MacArthur Foundation (EMF) reports progress, or lack thereof, on corporate packaging commitments set for 2025; plastic pact signatories increased portfolio of recycled, recyclable, or compostable products by 2% between 2019 and 2021; reuse decreased, and virgin plastic use increased; EMF calling for stronger governmental action and support of UN plastic pollution treaty

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
