Tegulys, a tile and brick manufacturer in the Haute Corrèze region of France, needs heat to power its dryer and firing process. However, more than 50% of the heat consumed in the baking oven is lost. With the Eco-Stock®, it is possible to capture and store the waste heat of the baking oven in order to recover it, at the desired time, in the dryer and the pre-baking chamber.

Aware of the economic and environmental profitability of such a project, the New Aquitaine region and theADEME have subsidized part of the infrastructure. Our network of partners then enabled Tegulys to finance the rest of the infrastructure via a financial lease.

“We are the first industrial site to have welcomed the Eco-stock® solution developed by the Eco-Tech Ceram company in 2019. The trust and support of the New Aquitaine Region were decisive in validating the merits of this solution and customizing it. Finally, we are doubly satisfied: the Eco-Stock® solution allows us to improve the energy efficiency of the firing process but also to increase our production capacity.”

As part of their commitment to decarbonization, Wienerberger wanted to create a partnership with Eco-Tech Ceram.

The Pontigny site (Yonne – Burgundy Franche Comté region) is going to equip itself with a thermal accumulator, our Eco-Stock®, to transform their heat losses into sustainable solutions.

Our thermal accumulator recovers the heat from their ovens to send it back to the dryers. This leads to a reduction in energy consumption of their tile factory which represents more than 480 Tons of CO2/year, or the equivalent of more than 3.5 million km per year for a normal car.

Its commissioning is scheduled for the first quarter of 2023.

“ With its Eco-Stock® solution, Eco-Tech Ceram will allow us to recover waste heat from the six Pontigny kilns and to use this waste heat in our dryers. This will allow us to avoid any gas consumption in the dryers and to save 480 tons of CO2 per year. ”

ArcelorMittal is one of the largest steel producers in the world and the Dunkirk site represents one of the largest production capacities in Western Europe. Wishing to play its part in the fight against climate change by reducing its CO2 emissions by 35% in Europe by 2030, the company is committed to numerous energy efficiency initiatives at its industrial sites in France.

Our prototype has shown the profitability of our solution for the recovery of waste heat for the drying of agglomeration sludge. This allows ArcelorMittal to avoid using fossil fuels to dry its sludge and to avoid paying the extra cost of transporting wet sludge.

See the data sheet

“The work we did with Eco-Tech Ceram allowed us to identify and prioritize several solutions for recovering waste heat: for drying sludge, for producing steam, hot water and electricity. Eco-Tech Ceram also provides a network of third-party financiers and financing solutions. The first Eco-Stock® was commissioned in April 2022 at the Dunkirk site. “
