Lafarge has signed a partnership agreement with US start-up cement technology company Solidia Technologies* to industrialise an innovative technology that could reduce the environmental footprint of precast concrete.

The technology allows lower CO2 emissions in the cement production process, and involves the capture of CO2 in precast concrete manufacturing. Overall, CO2 emissions could be reduced by up to 70%.

As part of the agreement, Lafarge will work with Solidia to demonstrate feasibility of commercial-scale production in the first half of 2014. The two companies will collaborate to market this technology as a new solution for the precast sector.

This partnership illustrates Lafarge’s commitment to bring to the market innovative solutions contributing to building better cities. Lafarge Research Centre, one of the world’s leading research facilities in building materials, holds a portfolio of more than 1 000 patents which has tripled since 2005.

Lafarge has been working for over 20 years to reduce its environmental footprint and, in particular, its CO2 emissions. These have been reduced by nearly 25% per ton of cement since 1990.

Solidia Technologies is a cement and concrete technology company with patented processes that make it easy and profitable to use CO2 to create superior and sustainable building, construction and industrial products.

Solidia’s processes cure concrete with CO2 instead of water and use a sustainable cement as binder, reducing the carbon footprint of concrete products up to 70%, lowering production costs, and enhancing performance. Solidia Concrete offers broader application choices in durability, strength, material reduction, and casting – using the same raw materials and equipment but less water, energy and time.
