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?

Many byproducts of PFAS "destruction" methods are other, smaller #PFAS, with unknown toxicity.

In this ES&T Viewpoint led by Sanne Smith we present the need & methods for tracking PFAS destruction methods to mineralisation and not other PFAS.

HEADPHONES ON! Stripes have illustrated the #climate crises, #biodiversity crises and recently the chemical #pollution crises, - with sound!

The heartbeat tracks time, the clicking noise growth in chemicals, the chords the patent numbers, while key events have their own sound.
