October 25, 2022 (press release) –


The new partnerships will enable limestone residues from the Rosignano facility to be re-used in construction and agriculture.

Solvay is partnering with two companies to collect and re-use the limestone residues from its soda ash production in Rosignano, furthering the company’s commitment to continually optimize the efficiency and sustainability of its operations. Pending further tests, the new partnerships could accelerate the decrease of limestone residues released into the sea, building upon the action plan announced in September to invest in new technical solutions at the site. 

Solvay and IPSIIS, a startup established in Wallonia, Belgium specializing in the manufacture of environmentally-friendly, non-flammable, lightweight and geo-sourced insulating mineral foams, are testing the use of soda ash manufacturing residues  to produce specialized construction products. Since 2018, IPSIIS has been labeled a “Solar Impulse Efficient Solution”.

Solvay is also working with the Italian subsidiary of Germany-based Ferro Duo, which specializes in recycling industrial materials, to use the inert solids from soda ash manufacturing as components of fertilizers to enrich soils where precious elements like calcium, sulfur, potassium, magnesium and iron are found.

“We are excited to work with IPSIIS and Ferro Duo to develop the capabilities to create a circular economy for our soda ash production in Rosignano,” said Philippe Kehren, president of Solvay’s Soda Ash & Derivatives division. “This is the latest example of how we are constantly looking for innovative ways to improve the sustainability of our operations, a key component of our Solvay One Planet Roadmap.” 

“The IPSIIS process enables the recycling of secondary products to produce lower carbon footprint materials. Partnering with Solvay in this circular economy program is key for IPSIIS’s development and fits totally with our company vision and daily commitment,” said Gilles Bocabarteille, IPSIIS Board Member and Managing Director.

"With more than 20 years of experience in the business of materials recycling and waste reprocessing, Ferro Duo is excited to be working with Solvay on this ambitious sustainability project and propose a new value-creating application for limestone residues from the Rosignano plant. Together we will develop new products and new market opportunities to recycle industrial residues  and create value and employment,” said Pietro Squilla, Managing Director of Ferro Duo.

Solvay ’s Rosignano facility has been manufacturing soda ash and sodium bicarbonate since 1912. These products are made from natural limestone and salt. They serve essential applications, such as the production of glass and air-pollution control systems, as well as applications in the healthcare industry, such as hemodialysis.

Improving the environmental footprint of all Solvay manufacturing sites is an ongoing effort as part of the Group’s holistic One Planet sustainability roadmap.
