Flame-retardant from waste water
Flame-retardant from waste water is what SusPhos, a start-up company led by Marissa de Boer, is making. The fundamentals have been laid by the University of Amsterdam and a pilot plant is now built at Paques. That company will also market the technology.
Marissa presented some details of the process at the NLGUTS meeting at Shell Technology Center, 3 September 2019. The starting material is struvite from municipal waste water. This material is converted to phosfor, amonia and magnesium salt by a chemical conversion and physical separations. The process is patented, but not yet published.
