Where CO2 Means Green and Sustainability
Solidia Technologies offers cement and concrete producers a way to manage CO2 responsibly. Cement producers emit less CO2 during the production of Solidia Cement™, and concrete producers consume less during the curing of Solidia Concrete™.
Solidia Cement: Less limestone and lower kiln temperatures translate into less CO2 and lower cost
Despite their chemical and process similarities—both are made from mixtures of limestone, clay and sand fired at elevated temperatures in rotary kilns—Solidia Cement and Ordinary Portland Cement (OPC) have distinct profiles, particularly in terms of sustainability and performance. The Portland cement industry is working hard to reduce their environmental footprint. When OPC is produced, it releases about 800 kg of CO2 for each ton of OPC produced. Approximately three-quarters of the CO2 is generated from the decomposition of limestone, and the rest from the burning of fossil fuels required to heat the kilns.
By contrast, Solidia Cement’s chemistry requires less limestone and can be fired at lower kiln temperatures. As a result, Solidia Cement can be manufactured while consuming 30% less energy and reducing the emission of greenhouse gases and other pollutants by up to 30% when compared to OPC.

Solidia Concrete: Sequesters approximately 5% of its weight in CO2 during curing
Solidia Concrete and OPC concrete are both composed of sand and aggregate, bonded together by a cement paste that hardens during a curing process. But while conventional concrete cures by a reaction between OPC and water, Solidia Concrete cures through the sequestration of CO2. During curing, Solidia Concrete sequesters approximately 5% of its weight in CO2.
The resulting product is a versatile and durable replacement for conventional concrete.
Solidia Concrete cures only when it is exposed to a CO2 -containing environment. This unique characteristic allows precise control of the curing process, permits the incorporation of a broad range of sands, aggregates (including those that cannot be used by the traditional concrete industry) and reinforcements, and enables concrete manufacturers to operate at higher speeds while minimizing material waste. Solidia Concrete parts can be designed for compressive strength, abrasion resistance, and freeze-thaw cycling resilience that are equal to, or better than, those of conventional concrete.
Solidia Cement and Solidia Concrete: Reduce carbon footprint of concrete products by 70%
When the reduced CO2 emissions associated with Solidia Cement production are coupled with the ability of Solidia Concrete to sequester CO2 during curing, the carbon footprint of the concrete products can reduced by approximately 70%.
Solidia makes all this possible by leveraging the cement and concrete industries’ existing capital investments and supply and value chains. It will make the adoption of its technology easy and cost-competitive by lining up cement, CO2 and equipment partners to collaborate with our customers along each step of the process.
When the reduced fuel costs associated with Solidia Cement production are considered alongside the raw materials, process and performance advantages, and ease of adoption offered by Solidia Cement and Solidia Concrete, both the cement and concrete industries may indeed envision a future where sustainability meets profitability.
