Solvay to install biomass boiler in Torrelavega facility

Solvay has announced it will phase out coal at its soda ash and bicarbonate plants with a new energy transition project in Torrelavega, Spain, aiming to nearly halve CO2 emissions by 2027 and ensure the site’s long-term competitiveness.
The Group secured a long-term energy supply agreement with ENSO, which will invest in, construct, and operate a biomass cogeneration unit for the production of energy.
This major biomass project will replace 70% of the plant’s coal usage.
The new biomass cogeneration unit will be Spain’s largest, repurposing byproducts from sawmills, forest maintenance, and wood supply for the pulp and paper industries.
All materials will be certified and sustainably and locally sourced within 100km of the site.
This initiative marks a milestone in transitioning the plant from thermal coal power to sustainable energy, supporting Solvay's actions towards carbon neutrality.
It builds on the successful energy transitions of Solvay's facilities in Rheinberg, Germany, and Green River, US, among others.
“With over 116 years operating in Spain, we are proud to transition the plant into a new era, marking a significant chapter in its history. This milestone is a giant leap in reducing our carbon footprint and delivering the most sustainable products to our customers,” said Etienne Galan, Solvay’s president for the Soda Ash & Derivatives business.
“Our broader plans for Torrelavega include offering our customers in Spain soda ash and bicarbonate with the lowest carbon footprint in the market. This project reaffirms our commitment to sustainable and competitive local production, ensuring long-term viability and success.”
"I am pleased that, through such an innovative instrument as the Energy Saving Certificates Scheme (CAE's), we have supported a key industry for the country and for Cantabria. Solvay Torrelavega is committed to sustainability and efficiency, an ambitious project that, thanks to this instrument, has the support of the government of Spain,” added Sara Aagessen, Spain’s Minister for Ecological Transition.
