Celanese and Siegwerk Partner on Biobased Ethyl Acetate for Sustainable Printing Inks
IRVING, Texas / SIEGEN, Germany — 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, recently 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% biobased 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.
Alignment with Sustainability Strategies
“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 at Siegwerk. “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.”
