Mined directly from its highest rank of coal, anthracite coal is a high carbon, low sulfur and low volatile content fuel.
A by-product of petroleum refining, petroleum coke (also called petcoke) is a high carbon, low ash fuel.
Through a 90 micron grinding-drying process, micronized coal offers high combustion stability.
Having a high volatile content, steam coal allows the combustion process to be stable and constant.
Used as a catalyst, iron oxide allows the clinkerization process to take place at a lower temperature, thus requiring less energy.
Setting regulator in the cement sector, Calcium Sulfate can be associated with Gypsum or be transformed into Anhydrite.
Of vegetable origin, wood pellets are natural and ecological fuels with the particularity of being renewable.
PEFC-certified forestry chips are adapted in terms of granulometry and humidity to ensure the best possible combustion.
CO2 certificates represent the amount of emissions that are offset. One certificate corresponds to one ton of greenhouse gases.
