This is the second article in a three-part series considering the challenges PFAS (per or poly fluorinated alkyl substances) present to the environment and potential options for overcoming such challenges. Part I of this series can be found here. The thermal stability and chemical inertness of perfluoroalkyl substances (PFAS) has led to these man-made chemical …
PFAS – the ‘Forever Chemical’
This is the first article in a three-part series considering the challenges PFAS (per or poly fluorinated alkyl substances) present to the environment and potential options for overcoming such challenges. In centuries past, chemistry was a dangerous profession. Carl Wilhelm Scheele (1742-1786) was dubbed “hard luck Scheele” by Isaac Asimov, because others often got credit …
Mann+Hummel’s Filter Cube poised to go global
A successful air pollution reduction scheme instigated by filtration specialist Mann+Hummel in Germany is set to be replicated at “hot-spots” around the world. As the home of both Mercedes and Porsche, Stuttgart owes its status as Germany’s richest city to the automotive industry, but in January 2019, a first partial car ban was imposed, effectively …
Are we on the verge of a stormwater catastrophe?

Certainly, such events are well documented in the geologic record, involving gamma ray bursts, asteroids and comets, and perhaps the biggest killer so far, volcanism. Volcanism is commonly accepted as the cause of the Permian-Triassic extinction, also known as …
