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. “

Villeroy & Boch has chosen to surround itself with committed players in order to bring about a real environmental and energy transformation of its production facilities in Valence d’Agen, and to this end is presenting a complete multi-year decarbonization program.

The technology we are going to implement will allow us to significantly reduce gas consumption and CO2 emissions on the plant’s two largest consumers. The company aims to save 5.5 GWh on its annual energy consumption, thus avoiding the emission of 1,000 tons of CO2 per year (global perimeter of the entire site).

Commissioning is scheduled for the spring of 2023.

“We produce ceramic products, a material that lasts over time thanks to a traditional know-how internationally recognized for its manufacturing quality. We had to quickly start our energy transition in order to make this noble material compatible with the ecological challenges to come. Manufacturing in France, in a sustainable way, in synergy with local actors, skills, and resources will make Villeroy & Boch a model of Social and Environmental Responsibility! “

The main objective of this project is to demonstrate the Eco-Stock®, a waste heat recovery solution by thermal storage, in a real environment on a European heavy industry production site. To this end, the Eco-Stock will be adapted to the specifications of the industry’s tunnel furnaces.

This solution solves one of the industry’s biggest challenges – increasing energy efficiency while reducing CO2 emissions and saving money.

This Eco-Stock® is installed in real conditions on an industrial site, at Villeroy & Boch in Valence d’Agen, the international ceramics giant. The Valence d’Agen plant has embarked on a genuine environmental and energy transformation of its production facilities.
