What is the core sustainability innovation in the Celanese–Siegwerk partnership?

The core sustainability innovation is Celanese’s supply of 50% bio-based ethyl acetate to Siegwerk, which serves as a drop-in replacement for conventional fossil-based ethyl acetate in Siegwerk’s existing printing ink formulations—enabling more sustainable products without compromising performance or requiring changes to manufacturing processes.

Why does Celanese emphasize collaboration in this initiative?

Celanese emphasizes collaboration because, as stated by Kevin Norfleet, senior director of sustainability, it is ‘key to driving meaningful progress toward sustainability’—specifically enabling reduced fossil resource use while maintaining the high performance standards required in demanding applications like printing inks.
