Cement production is responsible for approximately 5-7% of global manmade carbon dioxide (CO2) emissions. Given the scale of worldwide demand for cement, a more sustainable production method could have significant environmental benefits.
BP has invested in Solidia Technologies®, a company that has developed two technologies – one that reduces the amount of energy needed to make cement and another that captures and stores CO2 in concrete.
The first technology, Solidia's cement technology can be used in traditional cement kilns and reduces greenhouse gas emissions during the manufacturing process by reducing both limestone consumption and kiln temperature. Solidia has also developed a curing process that uses CO2 instead of water to turn cement into concrete. The CO2 is permanently and safely stored inside the concrete. As much as 80% of the water used to form the concrete products can be reclaimed for future concrete manufacturing.
Together, the technologies could reduce the carbon footprint of cement and concrete production by up to 70% compared to the manufacture of Ordinary Portland Cement and concrete.
Solidia Technologies can also enable both cement and concrete manufacturers improve their profitability through more efficient use of raw materials coupled with a significant energy savings. The company is planning to deploy its technologies at cement and concrete plants around the world, with manufacturing facilities using Solidia's technologies currently in operation in North America and Europe.
