Insights

  • Solvay is cutting 4,000 tons of CO₂ annually at its Dombasle, France plant by using biogenic CO₂ from Air Products, replacing ammonia-linked sources.
  • This move boosts sustainability and supply reliability.
  • It follows similar efforts at Solvay's La Rochelle site and supports the company's goal to cut scope 3 emissions by 20 per cent by 2030.
Solvay has taken a new step to reduce scope 3 greenhouse gas emissions by incorporating biogenic CO2 - provided by Air Products - into its soda ash and bicarbonate production plant in Dombasle, France. The initiative is expected to result in a reduction of 4,000 tons of CO2 emissions annually.

Air Products, a global leader in industrial gases, is supporting Solvay’s shift toward a more sustainable and reliable CO2 supply. With traditional ammonia-based sources becoming more challenging due to energy market fluctuations and decarbonization efforts, the move to biogenic alternatives offers both environmental benefits and improved supply reliability.

About half of the Dombasle plant's purchased CO2 needs are now met by regionally sourced, renewable CO2, derived from bioethanol fermentation byproducts. This transition not only supports Solvay’s climate objectives but also strengthens supply security by diversifying sourcing away from ammonia-linked production.

“This collaboration with Air Products is a concrete step in our journey to reduce scope 3 emissions and secure more sustainable operations,” said Anton Daniëls, Solvay’s Chief Procurement Officer. “By integrating biogenic CO2 into our processes, we are making our supply chain more robust and environmentally responsible.”

“We’re proud to support Solvay in advancing sustainable manufacturing through the use of the biogenic CO2 we supply. This collaboration reflects our commitment to enabling low-carbon solutions and building resilient supply chains for our customers. By leveraging sustainable CO2 sources, we’re not only reducing our customers’ emissions but also helping them transition to more sustainable and reliable operations,” said Frank Peeters, European Strategic Account Manager at Air Products.

The Dombasle initiative follows the successful implementation of biogenic CO2 sourcing at Solvay’s La Rochelle plant and is now being extended to the Rosignano site in Italy. These efforts reflect Solvay’s broader strategy to decarbonize its operations.

This partnership contributes to Solvay’s ambition to reduce scope 3 emissions by 20% by 2030 and highlights the role of strategic sourcing in advancing sustainable industrial practices.
