DS Smith has brought online a €90 million biomass boiler at its Rouen paper mill in Normandy, France – one of Europe’s largest mill energy transitions to date. The new system replaces the site’s coal-fired boiler with a low-carbon, circular solution powered by locally sourced biomass waste. The project is expected to cut CO₂ emissions by 99,000 tonnes annually – equivalent to removing 40,000 cars from the road or powering 13,000 French homes each year. The boiler will process around 94,000 tonnes of biomass fuel each year, including industrial and municipal waste wood – mainly from the Paris and Normandy regions – as well as paper production by-products. Up to 70,000 tonnes of wood waste will be diverted from landfill annually, supporting DS Smith’s 2030 zero-landfill target.
