CO2 negative facing bricks: Development and construction of a test installation for Vandersanden.

Our customer Vandersanden is introducing a revolutionary technique for making facing bricks that absorb instead of emitting CO2.

Customer request


The curing or hardening of the CO2-absorbing facing bricks was modeled and tested in the CEE Lab to attain an optimal specification for the test installation. The material must absorb CO2 under controlled conditions: temperature, moisture, air flow, time. Realizing this in a homogeneous and repetitive manner is the best way to guarantee consistent and qualitative products.

Based on the resulting parameters, the basic and detailed engineering of the curing room on an industrial TEST scale was realized. The prefabrication took place in the CEE workshops in Herentals. This TEST curing room was assembled and put into service at Vandersanden in Lanklaar in August 2020.


The installation contains all necessary elements and features:

  • 800 stones or 1500 strips can be treated at the same time
  • Humidification, heating, additive dosing, air rolling
  • Measurement of the process parameters
  • PLC control of valves, power controllers and motors to accurately realize the desired conditions  depending on the time
  • Registration of parameters and graphical visualization, accessible from the company's own network
  • Necessary safety features (pressures, temperatures, gas concentrations, LOTO)

This TEST curing room enables Vandersanden to develop the new product range in all facets and characteristics, according to composition, shape, color and technical requirements for building materials. Optimizing CO2 and energy consumption of the curing process is also part of the objectives.

CEE will continue to contribute to the realization of the industrial production process.
