SOLUTION BY: SOLIDIA TECHNOLOGIES www.solidiatech.com
Using CO2 to Make Concrete Cement manufactured by Solidia requires less energy to produce than conventional types, and is hardened by injecting industrial waste CO2.
SOCIAL : Solidia’s concrete recycles water, reducing the impact of the construction and building sector on water scarcity. ECONOMIC : Solidia’s technology saves the industry time and water, while using existing materials, making it easy and affordable to switch to sustainable building materials.
Solidia’s technology can sequester CO2 into construction and building materials. Solidia uses a chemical reaction during production requiring less limestone and lower temperatures than conventional methods, resulting in reduced CO2 emissions. To make concrete, the cement and sand mix is hardened utilizing mainly waste CO2 instead of water. According to Solidia, the technology can reduce CO2 emissions by up to 70% compared to conventional production. Solidia’s concrete is ready in about 24 hours, compared to 28 days with conventional methods. The durability and strength of Solidia’s concrete was independently verified by CTLGroup. Solidia has partnered with Lafarge, a building materials company operating in 61 countries, through which their technology will be commercialized. The first materials to be introduced to the market are paving stones, roof tiles, and concrete blocks. Why a Sustainia100 solution? The production of cement, used to make concrete, is responsible for up to 5% of total global carbon emissions.1 By binding waste CO2, rather than water, into the material instead of releasing it into the atmosphere, Solidia effectively reduces the carbon and water footprint normally related to concrete production.
