The new biomass boiler will go into operation by the end of 2025. Combined with other initiatives, such as sourcing green electricity from a major solar facility, this investment is a major milestone in transitioning the plant away from natural gas towards more sustainable and competitive sources of energy.

Solvay has entered into a long term partnership with Dalkia, a subsidiary of the EDF group and one of the major players in energy services, which will commission and operate. The biomass boiler will use locally-sourced wood waste from building demolition and waste furniture, as fuel to produce steam.
