Wienerberger reduces its carbon impact with innovative Eco-Stock® technology

This collaboration set up on the clay roof tile production site in Pontigny (89) will reduce the factory's CO2 emissions by more than 450 tonnes per year, thanks to the installation of a technological innovation: 'Eco-Stock®.

Last September, Wienerberger presented its environmental strategy aimed primarily at reducing CO2 emissions by 15% by 2023, 40% in 2030, until reaching carbon neutrality in 2050. To achieve its objectives, many actions have have already been implemented, such as the construction of heat exchangers on several structural brick manufacturing sites, saving 6 MWh/year on the gas consumption of a site, but also the use of 000% electricity green from a wind farm, among other things, or even the signature of a partnership with ADEME through a FRET100 system, for the reduction of CO21 emissions in the transport of materials.

Pursuing its environmental commitments, Wienerberger France is now joining forces with the company Eco-Tech Ceram for the installation of an Eco-Stock® on its historic site in Pontigny (89), specializing in the manufacture of roof tiles. Aléonard brand.

A true innovation dedicated to the energy transition in the industrial sector, the Eco-Stock® makes it possible to recover and store the fatal heat (or waste heat) rejected by the six intermittent furnaces of the factory. This heat accumulated in the Eco-Stock® will then be redirected wisely and at the right time to the dryers, which are also intermittent. Thus, these same dryers will no longer need gas to operate. Results: the site will considerably reduce its carbon impact by eliminating the emission of the equivalent in Co² of 6 km of car.

What is Eco-Stock?

A technological innovation from the Eco-Tech Ceram company, Eco-Stock® is a thermal storage system that can reach temperatures of up to 1°C and makes it possible to manage the intermittency and variability of deposits and energy consumption. The Eco-Stock® is able to capture, store and restore carbon-free energy that is less expensive than that resulting from the combustion of fossil fuels (natural gas, oil, etc.) by controlling the duration, power, temperature and flow rate of energy. The system makes it possible to make the best use of renewable and recovered energies in accordance with the performance requirements of the industry.

“We are very proud to launch this Eco-Stock® project on our Pontigny site, thus benefiting from the latest technological innovations from Eco-Tech Ceram. This facility, aimed at reducing CO2 emissions, is a new step in our decarbonization strategy with the ultimate goal of carbon neutrality by 2050.” comments Frédéric Didier, Managing Director of Wienerberger France.

“As the climate and energy crises intensify, we welcome our partnership with Wienerberger and are very pleased to be able to support this giant of the ceramic industry in its low carbon transition. With the Eco-Stock, we were able to offer them a turnkey technical solution that was fully financed, with the support of ADEME. By contracting with ETC invest, Wienerberger will therefore buy carbon-free and competitive heat to replace fossil natural gas, all without having to invest”, declares Antoine Meffre, President and Founder of Eco-Tech Ceram.
