R&D at wAys
The start-up wAys focuses its research and development activities on the drying and pyrolysis of wood (biochar) in a CO2-saturated atmosphere. We favour the use of biogenic and/or recycled CO2.
The drying of wood at atmospheric pressure and in a CO2-saturated atmosphere was completely unknown to science before wAys’ R&D work.
This programme of excellence in R&D, conducted internally and in collaboration with leading academic and industrial partners, has resulted in the filing of patents protecting our technological innovations. The R&D is based on the development of a drying and pyrolysis process using CO₂ with a view to industrial efficiency, energy performance and decarbonisation.
wAys technology is not only disruptive and profitable for the wood industry, but also represents a major opportunity for Europe to achieve its decarbonisation targets today.

Scientific partnerships
BIA
We are conducting R&D work on preserving the ultrastructure of wood during CO2 drying with the Biopolymers Interactions Assemblages Laboratory (BIA), INRAe.
LERMAB
Our research focuses on the thermal treatment of wood using CO₂ in collaboration with the Laboratory for Research and Studies on Wood Materials (LERMAB) at the University of Lorraine.
CNRS
Together with Professor Samuel Abiven's teams at CNRS – Ecotron IDF, we are working on CO2 pyrolysis and the production of wAys TM biochars.
Finally, we also have scientific collaborations on biochar produced under CO₂ with researchers such as those at IMT Atlantique.
