Caustic Soda

Caustic Soda 50% LowPCF – certified product excellence

Caustic soda is an important base chemical for numerous applications. BASF has now a certified LowPCF variety that helps customers to offer even more sustainable products.

Low Product Carbon Footprint
Caustic Soda 50% LowPCF from the Electrolysis plant Ludwigshafen, Germany.

Continous Opex

Saving of CO2 emissions through operational excellence. We continuously invest in our Verbund sites to futher save CO2 emissions. Every measure counts and can make a big difference.

New Technologies

BASF is working on new technologies to replace fossil-generated steam and to use waste heat of its various production plants.

Grey-to-green

To cover our demand for renewable energy, we are pursuing a make-and-buy strategy. BASF’s share in the Hollandse Kust Zuid wind farm is one example of the “make” part of our strategy for securing renewable energy. But BASF is also delivering on the “buy” part in the form of power purchase agreements (PPAs) with ENGIE and Ørsted.

2 BASF’s product carbon footprint (PCF) calculations follow the requirements and guidance given by ISO 14067:2018. In a methodology review, TÜV Rheinland has certified that the PCF methodology SCOTT developed and used by BASF SE for calculating the PCFs of BASF products is scientifically-based, is in accordance with ISO 14067:2018, and reflects the state of the art (ID-Nr. 0000080389: BASF SE - Certipedia).

What are Scope 3 Emissions?

Scope 3 Emissions

 

To serve our customers with the lowest carbon footprint materials possible, focusing only on reducing Scope 1 and 2 emissions is not enough. On average, around 70% of the carbon footprint of our products originates from our purchased raw materials (upstream Scope 3 emissions).

How is chlor-alkali made using membrane technology?

Membrane Cell Process

 

The consumption of electric energy is the lowest of the three processes and the amount of steam needed to concentrate the caustic is relatively low (less than one tonne per tonne of caustic soda)
The electricity consumption in membrane electrolysis can be significantly reduced by using renewable energy – this enables us to offer Caustic Soda 50% LowPCF.
