Vinnolit to offer green caustic soda with reduced CO2 footprint

25/02/2021

From 2021, Vinnolit will offer certified climate-friendly caustic soda utilising renewable energy Guarantees of Origin (GOs). The CO2 footprint of this low-carbon caustic soda from the Gendorf and Knapsack (Hürth) sites is reduced by more than 30% compared to conventional Vinnolit caustic soda. The CO2 footprint taken as a basis was calculated by sustainable AG in accordance with the ISO 14067 standard. Review and certification are carried out by TÜV Rheinland.

Vinnolit has been producing caustic soda in chlor-alkali electrolysis with the membrane process since 2009. Since the central process step is electrified, power from renewable sources can be used to save CO2 emissions by displacing fossil fuels. For more information, click here.
