Share to

Brussels, February 25th 2019 --- Solvay is investing in a new biomass boiler at its soda ash plant in Rheinberg, Germany, a decision that will cut the site’s CO₂ emissions by more than 30% while at the same time improving its competitiveness. 

The new biomass boiler technology – which burns recycled wood chips – will lower CO₂ emissions by 190 kt/year as the Group is committed to reduce its greenhouse gas emissions by 1 million tons over 2017-2025, regardless of its growth.

Solvay with this key project marks a critical step in achieving its new greenhouse gas target as part of our strategy to produce and serve our customers in a more sustainable and competitive way. This biomass project follows earlier energy transition initiatives we launched at our soda ash sites in Bernburg and Rosignano and shows how we shape our future and reinforce our global leadership in soda ash,” said Christophe Clemente, President of Solvay Soda Ash & Derivatives Global Business Unit.

The boiler, to come on stream in May 2021, will reduce fossil fuel consumption at Rheinberg by about a fourth. Supplies of waste wood to fuel the new boiler have been secured with a local company.
