Stopping the consumption of fossil fuel at the Ronneby plant, Sweden
Tarkett reduces emissions at its Ronneby, Sweden plant by replacing the site’s oil-fired boilers with electric boilers.Use non-carbon energy by switching from fuel oil
Reduce GHG emissions at the Lentzweiler site by eliminating the use of gas and stopping the incinerator
The project consists in installing a tri-generation plant (capacity 52kt of wood/year) in partnership with Engie close to the Tarkett plant.
This project is divided into several phases.
Phase 1:
Currently, the thermal oil used in the production processes is heated by the combustion of gas in two
gas in two boilers.
The thermal energy, supplied in the form of steam, will be used to heat the thermal oil
necessary for the process as well as the heating network of the buildings. It will also allow, thanks to an
It will also provide the cold necessary to produce the chilled water required for the process, thanks to an absorption unit.
This will reduce emissions by nearly 8400 tCO2 eq (7200 tCO2 eq for Cofely with the
transport of the Biomass).
Phase 2:
Another project related to the biomass installation is the shutdown of the incinerator currently used to burn
the fumes from the coating line in order to comply with environmental standards.
The incinerator would be replaced by a flue gas condenser.
Shutting down the incinerator would result in savings of 12 GWh/year and a reduction in emissions of 2800 t
CO2 eq.
These 2 joint projects would make it possible to stop consuming gas at the Lentzweiler site.
on which the project has a significant impact
Scope 1 - Stopping the consumption of gas for heating and production Shutdown of the incinerator
Scope 1 - Shutdown of the incinerator
Scope 2 - Heat (steam) imported from the trigeneration plant
Avoided Emissions -Injection of electricity produced from the trigeneration plant on the Luxembourg grid
The Lentzweiler site consumed 47 GWh PCI of gas per year before the project was launched. Considering
an average EF of 239 kgCO2/MWh PCI, this represented nearly 11.2 ktCO2/year.
The cessation of gas consumption for heating and production lines (thermal oil production) as well as the
production lines (thermal oil production) as well as the shutdown of the incinerator will enable the site to completely eliminate its gas consumption.
Phase 1 of the project, which consists of replacing the energy produced by the two gas boilers with the
tri-generation plant will reduce gas consumption by 28 GWh PCI/year for the process part and 7.3 GWh PCI/year for the heating part. We can therefore consider a total saving thanks to phase 1 of the project of about 8.4 ktCO2/year.
Phase 2 aims at stopping the incinerator and the associated gas consumption (12 GWh PCI/year). This is equivalent to to a reduction of emissions of about 2.8 tCO2eq/year (it is considered that the condenser does not smoke does not lead to GHG emissions).
Phases 1 and 2 therefore reduce emissions by 11.2 tCO2eq/year.
The energy required for the site's uses is now produced by the tri-generation plant.
The emission factor of this heat is very low compared to that of natural gas.
The production of the 47GWh (from the tri-generation plant) therefore leads to estimated marginal CO2 emissions (<1 tCO2/year).
The tri-generation plant allows the production of 36,3 GWh/year injected in the Luxembourg grid. In
considering that the emission factor of the electricity of the Luxembourg grid is 410 kgCO2/MWh
(Ademe carbon base). This makes it possible to avoid nearly 14.8 ktCO2/year.
