Geocycle Belgium



For many years, Geocycle Belgium has been providing waste management solutions for industrial waste through
co-processing, buidling industrial symbiosis with many waste producers like the chemical or petroleum industries to redirect their waste into its cement process. The company is a subsidiary of LafargeHolcim, the world’s no. 1 in the construction materials industry.

Geocycle Belgium provides a unique waste management solution thanks to its pre-treatment platform in Seneffe, and the strong partnership with the Obourg plant which co-process the pretreated waste into its 2 cement kilns.
This waste management solution offers an opportunity to divert a lot of waste from landfilling or incineration, without producing any ultimate residues.


Our services and waste streams

Geocycle offers an opportunity to divert a lot of waste from landfilling or incineration, without producing any ultimate residues.

Geocycle is able to receive various types of waste that can be pre-treated in our installations in Seneffe or directly recycled and recovered in the cement industry.  We can categorise our waste in different categories:

  • Liquid waste such as solvents, polluted water,…
  • Solid waste such as sawdust, fluff, …
  • Sludge/pasty waste such as sludge’s from waste water treatment plants, mineral slurry, paints, industrial sludges, ...
  • Mineral waste containing iron, alumina, silica,...  

Many waste streams co-processed by Geocycle are residues from other recycling operations for which this treatment completes the recycling and recovery process.

The prepared streams are both co-processed in the cement kilns in Obourg. Geocycle’s pre-treatment platform continuously strives for technological improvement by regularly investing in polyvalent production units in combination with increasingly high-performance installations in terms of environmental protection.


Our pre-processed solution in Obourg (BEMTI)

In Obourg, a unique pre-treatment installation (“BEMTI” = "Boue d‘Épuration Municipale et de Traitement Industriel") has been installed to dry and grind waste coal sludge mixed with sewage sludges, industrial sludges and fly ashes. The final material has energy content and mineral content replacing traditional fuel and primary mineral materials.
