Team CelSian

 

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!
