The Thermodynamics and Combustion Technology (TCT) laboratory along with Aalto Energy Platform would like to invite all interested colleagues to join the open lectures seminar titled: Sub/supercritical water innovation meets the forest industry. The seminar involves two main tracks. In the morning, after welcome greetings by the host Prof. Mika Järvinen and a keynote presentation by Prof. Herbert Sixta, industry experts from Metsä Fibre, Neste and St1 Renewables will present and join a panel discussion on circular economy practices within their own respective companies. This is followed, after lunch, with experts from leading EU research institutes presenting the latest developments and progress in the field of Sub/supercritical water innovation for energy and materials production.

Registration is open and for free, through this link. (Available until Friday 25th of May, 15:00)

Sub/supercritical water processes, referred to in some literature as hydrothermal treatment methods, are the processing of organic slurries at elevated temperatures and pressures, in the proximity of water’s critical point of 374 ⁰C and 221 bar. The interacting thermo-physical properties of slurry constituents vary significantly and present several processing opportunities compared to ambient treatment methods. For biomass refining and particularly lignocellulose, a versatile set of conversion pathways, that include water acting, as a solvent and/or reactant and/or catalysis, could be fine-tuned to produce a wide range of value-added bio- fuels, chemicals and materials.
