- 🌍 Mapping the chemical complexity of plastics - published in Nature Magazine! As countries negotiate a global treaty to address the plastic pollution crisis, in this new study we identify thousands of chemicals in plastics - many harmful and largely unregulated. www.nature.com/articles/s41...
- Mapping the chemical complexity of Plastics - now published in @nature.com! This we hope will be used as a launch pad to make plastics and materials more safer and circular!
- Over the past few years, our PlastChem team has worked tirelessly to map the chemical complexity of #plastics. Today, we publish the findings in @nature.com. We hope this evidence propels the development of safer plastics to protect human health and environment. 1/4 www.nature.com/articles/s41...
- Breaking #TFA news: The Danish Ministry of the Environment is withdrawing the approval of 23 #pesticides because the products contain active ingredients that can form and leach #TFA into groundwater. This is the first country to ban #PFAS pesticides. Press release (Danish): mst.dk/nyheder/2025...

- In this lysimeter study we studied the impact of using biochars to reduce mobility of PFAS in soil. Over 100 years, nearly all PFOS are predicted to leach from no-sorbent lysimeters, while < 1 % will leach from soil treated with sewage sludge- derived biochar. www.sciencedirect.com/science/arti...

- How can we restore #PFAS contaminated farmlands in a sustainable way? 👩🌾 We are piloting a new approach that involves a virtuous cycle of Phytoremediation, Pyrolysis, and Biochar Application. How does it work? pubs.acs.org/doi/full/10....
- 🪴 Step 1. #Phytoremediation - plants that can accumulate mobile PFAS, such as #TFA and #PFBS are planted on the soil. These can be selected based on their ability to "hyperaccummulate" PFAS, but ideally should be locally sourced plants/crops. These are then harvested for biochar production.
- 🔥 Step 2. #Pyrolysis - the mobile-PFAS contaminated plants are then pyrolyzed under conditions that mineralizes the PFAS within the plant, and converts the organic matter to PFAS-free Biochar. Optimizing for PFAS mineralization is key. Biochar is a stable form of carbon = negative GHG emissions.
-
View full threadThen one loop of the virtuous cycle is complete! Steps 1 - 3 are then repeated until the PFAS levels are safe for crops can be reintroduced. You can read read more about this virtuous cycle approach in the Journal of Agricultural and Food Chemistry, here: pubs.acs.org/doi/full/10....

- The costs of PFAS remediation: The more #PFAS are used and spread, the more the #health and #remediation costs. We conducted remediation cost estimates for soil, water, sludge and leachate for the EU27 countries, Norway, Iceland, Switzerland and the UK: foreverpollution.eu/lobbying/the...
- "Cleaning up the most concentrated sources of long-chain PFAS in Europe would cost €4.8 billion per year Getting rid of all PFAS €2 trillion over 20 years Short-chain and ultrashort-chain PFAS, like TFA, are extremely mobile and can very easily enter the cells of living creatures."
- Three main take aways: 1) The most cost-effective way of managing PFAS is to prevent production, use and emissions in the first place, as supported by the broad PFAS restriction in the EU

- Excellent (and sad) commentary by C&EN on the shift in the US from briefly lifting resilient, future-oriented eco-innovation towards fossilized economic models of profit by destruction, and short-term gain for long-term pain. Other nations need to stand up to prevent Earth becoming more Mars like.
