The vendéen Hoffmann Greenspecializing in low-carbon cements, is participating, in collaboration with Eiffage Génie Civil, in the construction of an industrial prototype dedicated to the recycling of deconstruction glass wool for the account of Isover, leader in sustainable building insulation and subsidiary of the Saint-Gobain group, in the town of Chemillé-en-Anjou (49). In the continuity of its Isover Recycling offer, the first in the world to recycle used glass wool from buildings, the company is stepping up its development in favor of a circular building economy. It thus began the low-carbon-footprint construction of the industrial prototype dedicated exclusively to the recycling of glass wool. With commissioning scheduled for 2023, this unprecedented pilot facility meets the ambitions of the Saint-Gobain Group to achieve carbon neutrality by 2050.
