Fires can be extinguished in an environment-friendly way.
Water- and grease-proof coatings, meanwhile, often contain substances which are hard to break down. They are
already found in drinking water: so-called ‘forever chemicals’ belonging to the PFAS group.
Among others, a research team from the University of British Columbia is after them and has developed a new material that can filter up to 99% of PFAS particles from water.
Subsequently, they were broken down in a lab chamber filled with sulphur electrolyte. For this, the liquid was stirred and electrified by a boron-doped diamond anode and a stainless steel cathode.
Other initiatives are already removing lithium from industrial wastewater, while this magentic liquid captures microplastics in water.
