Team CelSian
Â
As an independent entity we support all major glass manufacturers and suppliers around the world with our services. In our diverse team we have leading academic experts as well as hands-on operational experience from various glass segments.
CelSian is employee-owned. We are not a traditional company, but merely a movement. We are all driven by making a positive impact to this planet, and believe glass can become a crucial element of a circular economy.
We are your partner for future-proof glass!
