TreaTech SA

TreaTech is a Swiss Cleantech company founded in 2015 by EPFL engineers. We are developing a ground-breaking treatment technology that will enable an eco-friendly treatment of the ever-increasing quantities of wastewater while recycling its valuable by-products and most notably, clean water. Our catalytic hydrothermal gasification (HTG) system has been developed for the disposal of different types of liquid wastes (such as sewage sludge) that are usually incinerated or landfilled and instead, turns them into by-products such as methane-rich renewable gas, clean water, and mineral salts that can further be upgraded into phosphorus products (e.g. fertilizers).
