Air Liquide renews its collaboration with Solidia®

10 February 2020

After a successful pilot phase, Air Liquide renews its partnership with Solidia Technologies, a developer of solutions to reduce the environmental footprint of precast concrete manufacturing.

During the pilot phase initiated in 2016, a joint team of Air Liquide and Solidia Technologies experts has industrialized the innovative solution Solidia ConcreteTM, which uses carbon dioxide (CO2) to cure concrete. The combination of the consumption of CO2 during curing, and lowered carbon emissions achieved in the production of low-energy Solidia CementTM that is used to bind the concrete, results in an up to 70% reduced carbon footprint compared to traditional concrete.

As part of this partnership, Air Liquide is Solidia's preferred supplier of CO2 and the equipment used for its injection. In the United States, where sales of Solidia Concrete have been launched, Airgas, an Air Liquide company, supplies the carbon dioxide recovered and purified from CO2 emitted by other industries.
