A new type of carbon capture and utilisation (CCU) technology will be implemented in a pilot installation at Lehigh’s Redding California cement facility, with an expected 60% reduction in CO2 emissions per tonne of product.
HeidelbergCement’s US subsidiary Lehigh Hanson and Silicon Valley-based materials technology company Fortera confirmed the news last week (12th March), stating that they have joined forces for the effort.
Under the project plans, both partners will construct and operate a small commercial plant where CO2 will be captured from the kiln exhaust and converted into a cementitious material.
The final product will be the first cementitious material produced commercially from CO2 captured directly from a cement kiln and will be suitable for use as a new low carbon supplementary cementitious material (SCM) in the production of high-quality concrete with a lower CO2 footprint.
