Papermaking equipment involves significant energy consumption. We are one of 523 electricity-intensive companies in France, with an annual consumption of nearly one terawatt-hour.
Papermaking equipment involves significant energy consumption. We are one of 523 electricity-intensive companies in France, with an annual consumption of nearly one terawatt-hour.
Our ISO 50001 certified energy management system ensures that our impact and consumption are monitored and controlled.
The Norske Skog Golbey site is supplied by the public distribution grid via a 225 kV line. This line serves three transformers that distribute electricity to substations.
We support the French electricity grid by working closely with RTE, the transmission system operator. We are committed to reduce our electricity consumption at peak times, and particularly during periods of extreme cold.

The papermaking process requires a significant amount of steam. To produce this steam, we have a fleet of four boilers: a biomass boiler, coupled to a cogeneration turbine that produces electricity, and three backup gas boilers, which are activated in the event of a breakdown or maintenance of the biomass boiler.
At the same time, in partnership with the GVE project company, we are building a new cogeneration turbine combined with a new biomass boiler (with twice the capacity of the existing one) to the north of our site.
These boilers supplied by sludges produced by our wastewater treatment plant and end-of-life wood (demolition wood from waste disposal centres) make it possible to produce energy from renewable sources.
In 2022, for example, 90% of the steam produced was of non-fossil origin.

We recycle waste wood
In 2016, we built our first unit for producing biogas from our effluents. A second unit is currently under construction. This will double our biogas production capacity. These two units have the advantages of:
Enabling us to reuse our effluents through a bioeconomy approach
Reducing our electricity consumption and the use of chemicals in the treatment of our effluents
Reducing fossil CO₂ emissions and thus our carbon footprint
Continuing our commitment to bioenergy
As part of our ISO 50 001 certification, we follow an EPP to optimise the energy performance of our production workshops. As a result, and thanks to our diversification, we will further reduce our energy consumption by 2025.
| -30% electricity due primarily to shutting down the most energy-consuming workshop (wood pulp production) | -50% fossil natural gas thanks to the construction of a biomass boiler fuelled by end of life wood |
