Geocycle Belgium


Geocycle Belgium has been providing, sustainable waste management solutions for over 30 years, to industrial customers located in the Benelux, Germany, Italy and Northern France.

This includes the entire process of inventory, analysis, acceptance, possible pre-treatment and recovery of the waste.

In 2020, over 400.000 tons of waste were co-processed in the Obourg kilns. About 100.000 tons were pre-treated at the Geocycle platform in Seneffe, whilst the other 300.000 tons were directly delivered to the Obourg cement plant.

This is an example of the circular economy at its best: the energy and mineral content of the non-recyclable waste in closed circuit are recycled and recovered in the clinker manufacturing kilns. By means of co-processing, we are committed to a 100 % use of the waste, without leaving behind any residues.

Mineral waste

Contaminated soil, construction and demolition waste, waste containing Al, Fe, Si, decarbonated calcium sources (slag, ashes, …)


Dried sewage sludge, animal meal, wood dust, impregnated sawdust, contaminated plant seeds and other plant based debris


Solvents, water based solvents, waste oils, waste emulsions, polluted water

Geocycle Seneffe - Geocycle Obourg, our pretreatment platforms

The Geocycle platform in Seneffe can pre-treat the following waste streams:

  • Liquids - usually classified as hazardous waste - such as low flash points solvents. This unique concept, makes Geocycle Seneffe a reliable partner for the acceptance & processing of these waste streams coming from the Benelux area, but also from other European countries.
  • Solids to integrate into impregnated sawdust consisting of : sawdust / wood dust, a waste type mainly coming from the wood processing industry, and pasty sludges - usually hazardous - such as paint waste, bottom fractions from oil storage tanks and alikes.

Geocycle Seneffe has been classified as a high-level facility according to SEVESO standards since 2015.

The cement kilns in Obourg offer fully circular solutions for non recyclable waste and alternative raw materials.

Below a list of materials that are recovered and/or recycled in the cement manufacturing process:

  • Liquids such as solvents, hot solvents (which solidify at ambient temperature) and waste waters,
  • Dehydrated sludges/filter cakes which are dried and grinded in a dedicated installation called “Bemti”,
  • Impregnated sawdust,
  • Mineral waste based on Al, Ca, Fe and Si,
  • Fluff/SRF from waste processing sites.

Environment and Safety

The implementation and success of an environmental management approach within a company requires mobilization and engagement from all stakeholders: from the management to the workers, including the subcontractors and the visitors.

This is why well thought out and regular awareness campaigns are essential to achieve sustainable behavior change.

Strict respect of our legal obligations, reduction of our carbon footprint, reduction of air and water pollution, care for the biodiversity and our local stakeholders are therefore regularly monitored & discussed.
