Speeding up the energy transition across our sites
True to its commitment to reducing its environmental footprint, Laïta is embracing innovative solutions to make its industrial operations more sustainable and less carbon-intensive. The launch of the first biomass boiler at the Créhen site is a prime example.
De-carbonised steam
Damien, Energy manager and biomass project manager
« From June 2025, 72% of the steam used in industrial processes at the Laïta site in Créhen will be decarbonised thanks to the commissioning of a biomass boiler. With an annual capacity of 9 MW, this facility will generate 57,600 MWh of heat in the form of steam, equivalent to the consumption of almost 6,000 homes. It will therefore reduce our dependence on natural gas and save 12,000 tonnes of CO2 equivalent per year.
This project is based on the collaboration of several partners:
- As an investor, Guyot Energies supplies the 17,000 tonnes of end-of-life wood needed to run the boiler each year. This wood, collected from nearby waste collection centres, is prepared and recycled as fuel;
- Dalkia, which acted as prime contractor for the design and construction of the project will assume the dailyoperation of the boiler;
- Laïta, as a consumer of the energy generated by the biomass. »
Coordinated, innovatory construction at work
« For the past two years, I’ve been coordinating all the partners to ensure that the project runs smoothly, in particular by keeping to the schedule and meeting safety requirements. Laïta has invested over one million Euros to interface the production of this biomass boiler with its industrial processes. My role as project manager was to ensure the hydraulic and electrical interconnection of this new boiler with the two existing gas boilers. A new feeder has been created to centralise the regulation of the three boilers and adjust steam production according to the site’s needs. On the electrical front, a new PLC has been installed to collect data from the boilers and maximise the use of carbon-free steam. The aim is to make maximum use of the steam from biomass and to supplement requirements with gas boilers if necessary. The main challenge of this project was to carry out all the work while limiting the impact on production. Over a period of four months, we successfully conducted the electrical, hydraulic and automation work, with only 8 hours of planned downtime on site, which is a real achievement. This was made possible thanks to the involvement of Laïta’s operational teams, technical services and technical management, while guaranteeing strict compliance with safety regulations and internal procedures.»
