A world first at Wienerberger Francethe world leader in terracotta! They entrusted us with the installation of a system to capture and recover waste heat from several kilns and dryers simultaneously!

And the results speak for themselves: they will be able to reduce their energy consumption by 15% and avoid the emission of 500 tons of CO2 at their Pontigny site!

We have just commissioned a new waste heat recovery solution:

  • Pressure-controlled fume extraction on several intermittent baking ovens, ensuring product quality
  • Heat capture and storage in our Eco-Stocks® (2.3 MWH at 600°C)
  • This decarbonated heat is used in several intermittent dryers to control humidity and, here again, ensure product quality.

The entire technological innovation was financed by ETC Invest, with the support ofADEME and ADEME Investissement. In concrete terms, this means thatETC Invest sells the decarbonized heat to Wienerberger France(at a competitive fixed price for the next 10 years).

Wienerberger France now benefits from many advantages without investment:

  • Better control of production conditions through supervision of kilns and dryers
  • Reducing CO2 emissions
  • Reduce energy bills and dependence on fossil fuels
  • Protection against gas price volatility (tariff shield) thanks to fixed price for decarbonized heat.

Wienerberger France has placed its trust in us, and we have kept our promises.
