The production of cement is responsible for approximately 5-7% of global man-made carbon dioxide (CO2) emissions. Given the scale of global cement demand, a more sustainable method of production could have significant environmental benefits.
Solidia Technologies aims to do this in two ways – by manufacturing cement using less energy and by capturing and storing CO2 in concrete. These two technologies offer the potential to reduce the carbon footprint of concrete production up to 70%, and water consumption by 60-80% compared to the manufacture of Ordinary Portland Cement1.
Solidia’s cement technology, can be produced in traditional cement kilns and reduces greenhouse gas emissions during manufacture by 40% through reducing the kiln temperature and amount of limestone used. Solidia also has developed a concrete curing technology that permanently and safely consumes CO2 to harden concrete products, leaving 3-5% of the finished product weight as solid CO2. The water used to form the concrete products can be reclaimed for future concrete manufacturing.
Solidia has made its technologies easy to adopt for any application anywhere in the world using the industry’s existing infrastructure, raw materials, formulations, production methods and specifications. Solidia is planning to deploy these technologies at cement and precast concrete plants around the world, with manufacturing facilities currently in operation in North America and Europe.
