The main activities of GEOCYCLE Liquid Fuel Production (N°3)

Fuel blending of waste solvents and waste water.

Solid Fuel Production (N°4,5,6)Industrial hazardous and non hazardous Sludge's and pastes are crushed and mixed with sawdust (impregnation base). The process is fully automated. After 10mm screening, the product is stored and analyzed before being sent to the cement works to be insufflated into the kilns.

WWT sludge After blending waste water treatment sludge is shipped to the sludge drier of Holcim Obourg where they are uses as fuel and raw material

De advantage off recovery in the cement kilns

Recovery of energy: Saving of fossil fuel

Reuse material (raw material) : Saving of non replaceable natural raw materials

Reduction CO2 emission

No rest products (ashes)

A method according to the priorities of the European Union and the Walloon Federation

Recovery in numbers

Substitution of fuel 68% of the energy demand of the cement kiln

Fuel saving? (via GEOCYCLE) Energy equal 90.000 tons crude oil

Raw Material savings (via GEOCYCLE) 60.000 tons natural material
