Hoffmann Green Cement Technologies (ISIN: FR0013451044, Ticker: ALHGR) (“Hoffmann Green Cement” or the “Company”) (Paris: ALHGR), an industrial player committed to the decarbonization of the construction sector which designs and distributes innovative cement without clinker, is participating, in collaboration with Eiffage Génie Civil, in the construction of an industrial prototype dedicated to the recycling of deconstructed glass wool for Isover, a leader in sustainable building insulation and a subsidiary of the Saint-Gobain group.

Concrete pours made with Hoffmann Green H-UKR cement are multiplying and are currently used by teams from Eiffage Génie Civil for the construction of the foundations of a prototype workshop for the Isover company located in Chemillé-en-Anjou ( West of France). In the continuity of his Isover Recycling offer, the world’s first recycling offer for used building glass wool, the company is accelerating its development in favor of a circular economy in the building sector. It has started work on the low carbon footprint industrial prototype dedicated exclusively to the recycling of glass wool. With commissioning scheduled for 2023, this unprecedented pilot facility meets the strong ambitions of the Saint-Gobain Group to achieve carbon neutrality by 2050.

Julien BLANCHARD and David HOFFMANN, Co-founders of Hoffmann Green Cement Technologies, declare: “It is an honor for us to participate in this exceptional project by delivering our H-UKR cement to build the foundations. This unprecedented project is totally in line with what we have wanted to embody since the creation of Hoffmann Green: the promotion of the circular building economy by recycling industrial waste It is thanks to initiatives such as those developed in collaboration with Isover and Eiffage Génie Civil that the decarbonisation of the construction sector will take place.

Jérôme Saulnier, Technical Director of Isover France and Switzerland, explains: “The realization of this revolutionary industrial prototype with melting by submerged burners will make it possible to recycle glass wool in industrial quantities to transform it into cullet (broken glass). This facility will reduce our consumption of raw materials: this cullet will be used in the manufacturing process of our insulation products and will also reduce our energy consumption, our carbon emissions and improve the life cycle of our products. The use of this low carbon impact concrete for the construction of the building contributes to our sustainable development approach.

Benoît LE MEE, business manager of the Nantes branch of Eiffage Génie Civil, explains: “Improving the environmental performance of our projects, in particular by reducing CO2 emissions on our sites, is one of the objectives of our 2022 performance policy. The use of Hoffmann low-carbon concrete has become obvious for this project. creation of a building to recycle used glass wool.


Founded in 2014 and based in Bournezeau (Vendée, West of France), Hoffmann Green Cement Technologies designs, produces and distributes innovative, extremely low-carbon cements – with a carbon footprint 6 times lower than that of traditional cement – ​​which, at equivalent and without modification of the concrete manufacturing process, superior performance to traditional cement.

With an industrial 4.0 site powered by a fleet of solar trackers and two new sites under construction, the Group has industrialized a real technological breakthrough based on the modification of the composition of cement and the creation of a sector without heating, without clinker and low power consumption. manufacturing process that makes it a leading and unique player in a cement market that has not experienced significant development over the past 200 years.

In the context of climate emergency and energy price inflation, Hoffmann Green Cement is thus actively participating in the energy transition by producing clean cement that consumes 10 to 15 times more energy than Portland cement, by working creating eco-responsible buildings and encouraging the circular economy and the preservation of natural resources. Thanks to its unequaled and constantly improving technological know-how, supported by efficient and cutting-edge teams, Hoffmann Green Cement Technologies addresses all markets in the construction sector, in France and abroad.
