One of Europe’s largest mill transformations, the Rouen biomass boiler project is pioneering circular economy practices, cutting CO2 emissions by 99,000 tonnes annually and saving local wood waste from landfill.
Our new biomass boiler has been activated at Rouen paper mill, marking a transformative €90M investment in low-carbon energy infrastructure.
Cutting Emissions With Circular Energy Solutions
The cutting-edge project replaces the mill’s coal-fired boiler with a renewable energy solution powered by biomass waste, driving significant reductions in greenhouse gas (GHG) emissions and accelerating DS Smith’s journey to Net Zero.
The new boiler, which will process approximately 94,000 tonnes of biofuel annually, will reduce carbon emissions by 99,000 tonnes per year and eliminate the mill’s reliance on fossil fuels. In real terms, the volume of carbon emissions removed is roughly equivalent to the annual energy use of around 13,000 French households, or taking around 40,000 cars off the road for a year.
Using Local Waste Wood to Power the Mill
The approach taken at Rouen is a circular one. The biomass used will be sourced from local industrial and municipal waste wood including construction and furniture waste, with 70% sourced from Paris and 30% from Normandy, as well as by-products from our own paper production processes. This circular approach will divert up to 70,000 tonnes of waste wood from landfill each year, aligning with our 2030 zero-landfill target.
This project illustrates the integration of circular economy principles into the energy transition. By diverting wood waste from landfills and transforming it into a valuable energy resource, DS Smith is contributing to France’s decarbonisation goals.

A Collaborative Project Backed by French Authorities
The Rouen biomass boiler project is one of several initiatives we have launched across Europe to modernise the business’ energy infrastructure. The boiler’s activation is the culmination of 9 years’ collaborative planning with the French government, and industrial partners.
Aligning with France’s Green Industry Bill and the European Green Deal Industrial Plan, the groundbreaking project was granted approval by the Regional Biomass Scheme in 2022 and is supported by local authorities including a €15M subsidy from the French Agency for Ecological Transition (ADEME).
Engie Solutions
Engie Solutions will oversee the boiler’s operation, with future plans to incorporate a steam turbine capable of generating 10 MW of electricity. This collaboration reflects the shared commitment of DS Smith, local authorities, and industrial partners to France’s green energy transition.
We are proud to work with DS Smith on this biomass project, showing how renewable energy can decarbonize industry. By using waste as fuel, it proves biomass can scale locally. Together, we’re driving greener, more efficient manufacturing in France.

The Rouen project underscores the advantages of France’s established wood recycling and biomass infrastructure, which has been in place since 2011. France is unique in this space in having the long-term strategic framework needed to attract comparable investments in renewable energy.
The Rouen biomass boiler exemplifies a transitional energy solution that complements longer-term efforts toward decarbonization, such as hydrogen and electrification. By leveraging waste biomass as fuel, DS Smith ensures resource efficiency while contributing to the circular economy.
This investment supports our sustainability goals and shows how public-private partnerships can drive a low-carbon economy. It gives manufacturers confidence to act, showing how strong policy and infrastructure can enable decarbonisation across Europe.

Paper Cluster Director, DS Smith
Pierre Jegu, DS Smith, continues: “Our €90M investment in the Rouen biomass boiler demonstrates our commitment to reducing emissions and driving innovation in renewable energy. This project highlights the importance of leveraging waste materials to create sustainable solutions while meeting the energy needs of our operations. France’s well-established recycling infrastructure made this possible, and we hope to replicate this approach elsewhere.
“The Rouen biomass boiler is a critical step on our journey to Net Zero. By rethinking how waste wood is used, we’re delivering significant carbon savings and promoting a circular economy. This project reflects the power of collaboration between industry and government in creating impactful change.”
