Solvay to reduce limescale waste

Solvay has made plans to reduce the limestone residues released into the sea from its soda ash production plant in Rosignano, Italy.

This is part of the group’s efforts to imnprove the efficiency and sustainability of its operations, and in line with its Integrated Pollution Prevention and Control (IPPC) permit which was renewed in January 2022. The IPPC covers the minimizing of pollution from various industrial sources throughout the EU.

The company also plans to invest €15 million investment to improve the production process and limestone granulometry and quality.

Solvay's objective is to lower by 20% the maximum volume of discharge currently set by the IPPC permit by 2030, and by 40% at the end of 2040.

“We are committed to constantly improving the sustainability of our processes and focused on ensuring that our Rosignano facility will continue to play an important role in providing essential materials for society,” said Philippe Kehren, president of Solvay’s Soda Ash and Derivatives division.
