Vinnolit GreenVin® Caustic Soda

For the production of Caustic Soda Solution (NaOH 50%) GreenVin® we use Renewable Energy Guarantees of Origin (GOs/HKNs). Thus, the carbon footprint of Vinnolit GreenVin® caustic soda is reduced by about one third compared to our conventional caustic soda.

Caustic soda is an important base chemical, of which more than nine million tons are needed per year in Europe alone. From 2021, Westlake Vinnolit will offer certified climate-friendly caustic soda utilizing renewable energy Guarantees of Origin (GOs). The CO2 footprint of this low-carbon caustic soda from the Gendorf and Knapsack (Hürth) sites – which is introduced to the market under the brand name GreenVin® – is reduced by more than 30% compared to conventional Westlake 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.
