Celanese is partnering with Siegwerk to support more sustainable ink production by supplying bio-based ethyl acetate containing 50% bio-based content, reducing reliance on fossil-derived raw materials across the printing-ink value chain.

What impact do you think a 50% bio-based solvent could have on the overall footprint of printing inks, and what other steps should the industry prioritize to advance sustainability?

Is that 50% bio content via physical segregation or ISCC mass-balance, and does the impurity profile (water, acetaldehyde, acidity) stay inside current EtOAc specs? Our ink dryers and solvent recovery columns are unforgiving, and VOC permits don’t care if it’s bio, so can you share the LCA (kg CO2e per kg) to show the real plant impact?
