Swiss start-up TreaTech, launched in 2015 in Lausanne by Frédéric Juillard, CTO and co-founder, is developing an innovative catalytic hydrothermal gasification technology. This technology enables waste and liquid residues to be converted into green, renewable gases.
The process uses water under supercritical conditions (operating at 250 bar and 450°C) as the reaction medium, which can be recovered at the reactor outlet, along with the process co-products (phosphorus, potassium). The advantages of this technology over other waste-to-energy technologies are the speed of conversion and its compactness.
In order to accelerate the development and optimisation of its technology with a view to its industrialisation, TreaTech has just signed a collaboration agreement with the CRIGEN Lab, aimed in particular at further enhancing the performance of its process under supercritical conditions. Amine Dalibey, Finance and Business Development Director at Lab Crigen, stresses that the aim of the work being carried out in collaboration with the Biogas, Biomass & Waste Lab is ‘to ensure that the unit operates smoothly and to be able to use inputs from a variety of sources in order to expand the technology's market’.
During a visit by Lab Crigen teams to the Ecorecyclage SA site last September, TreaTech was able to present the VISTA pilot plant, which will be commissioned shortly and which aims to produce gas by the end of 2024.
