About us

Re-inventing chemistry
We develop disruptive chemical production processes by rethinking them from the atomic level all the way up to production scale.
We explore new chemistries by employing quantum-chemical simulations and transfer them into proprietary production technology.

Designing green processes
We develop & scale our new technologies based on renewable feedstocks & energy. From the very first steps in the development of a production process, we design it to enable closed carbon loops. Without compromise.

Defossilizing industries
With our climate-friendly chemical technologies we support industries in their net zero journey. Our first disruption is the proprietary C1 methanol technology. It unlocks green methanol production by overcoming long-standing challenges.
