DALLAS & SIEGBURG, Germany--(BUSINESS WIRE)--$CE--Celanese, a global chemical and specialty materials company, and Siegwerk, one of the world’s leading providers of printing inks and coatings for packaging applications and labels, today announced a collaboration to supply more sustainable solutions in the printing ink value chain through utilizing bio-based ethyl acetate manufactured by Celanese.

The ethyl acetate produced by Celanese contains 50% bio-based content, helping to reduce the use of fossil-derived raw materials compared to conventional alternatives. Siegwerk uses the bio-based solvent as a drop-in solution in its existing ink formulations, enabling the production of more sustainable products without compromising performance or requiring changes to established manufacturing processes.

“The partnership with Celanese directly aligns with Siegwerk’s SustainUP program, our global sustainable procurement initiative, which is a key pillar of HorizonNOW 2030 – Siegwerk’s overarching sustainability strategy,” said Cathleen Hansohm, Global Supplier Sustainability Manager. “The use of a 50% bio-content ethyl acetate supports our ambition to expand the use of renewable feedstocks in a responsible and scalable way.”

“Collaboration is key to driving meaningful progress toward sustainability,” said Kevin Norfleet, Senior Director, Sustainability, at Celanese. “By working closely with Siegwerk, Celanese contributes to solutions that reduce the use of fossil resources while maintaining the high performance standards required in demanding applications such as printing inks.”

The initiative highlights both companies’ shared commitment to advancing sustainability through practical, scalable solutions that deliver tangible environmental benefits while reinforcing the critical role of value-chain collaboration in enabling truly sustainable packaging.
