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 theEco-Stock®it’s possible to capture and store waste heat from the baking oven, so that it can be used at the right time in the dryer and pre-bake chamber.

Aware of the economic and environmental profitability of such a project, the Nouvelle Aquitaine region andADEME 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, a giant in industrial bricks and tiles, has decided to form a partnership with Eco-Tech Ceram.

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

Our thermal accumulator recovers the heat from their ovens to send it back to the dryers. The result is a reduction in energy consumption at their tile factory of over 480 tonnes of CO2/year, equivalent to more than 3.5 million km per year for a normal car.

It was commissioned in early 2024.

“ 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. Enabling Wienerberger to use 100% waste heat for drying its roof tiles, all the while eliminating 100% of natural gas consumption and achieving carbon-free drying.. “

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 means that ArcelorMittal does not need to use fossil fuels to dry its sludge, and no longer has to pay the extra cost of transporting wet sludge.

“The work carried out with Eco-Tech Ceram enabled us to identify and prioritize several solutions for recovering waste heat: for sludge drying, and for steam, hot water and electricity production. 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 at Valence d’Agen. The manufacturer then prepared a comprehensive multi-year decarbonization program.

The technology we’ve implemented has significantly reduced gas consumption and CO2 emissions at the plant’s two biggest consumers. The company is aiming to save 8 GWh on its annual energy consumption, thus avoiding the emission of 1,400 tonnes of CO2 per year (global scope for the entire site).

“The plant will thus reduce its gas consumption by 42% compared with 2021. Without this saving, the site would be threatened by rising gas prices.”

The main objective of this project is to demonstrate theEco-Stock®our solution for recovering waste heat by thermal storage, in a real-life environment on a European heavy industry production site. To this end, the Eco-Stock® is installed in real conditions on an industrial site: Villeroy & Boch in Valence d’Agen, the international ceramics giant. It is directly adapted to the specifications of the tunnel furnaces of the site.

The Valence d’Agen plant has embarked on a genuine environmental and energy transformation of its production facilities.

This solution solves one of the major challenges facing industry today: increasing energy efficiency while reducing CO2 emissions and saving money.

“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! “

In 2018, Aubert & Duval, a giant in high-end metallurgy, established a decarbonization strategy.

The goal? Reduce their greenhouse gas (GHG) emissions by 45% in 2030 (123,000 tons of CO2 equivalent emissions). After five years, they needed to find other levers and turned to Eco-Tech Ceram.

The project? Hot fumes from the metallurgist’s furnaces will be directed to a heat exchanger. With it, hot air will be produced which will feed the burners. As a result, the manufacturer expects to reduce CO2 emissions from its gas furnaces by 20-25%.

“We have already reduced our emissions by 39%, but with the mitigation of the pandemic and the jolts in aviation, we expect to see some pretty significant upturns in activity. To meet our decarbonization trajectory, we need to go much further! That’s why we turned to Eco-Tech Ceram, a company that specializes in energy efficiency.”
