World’s first net zero-emissions cement production trial starts

Production trials are starting on the world’s first commercially available zero-emissions cement.

The process developed at Cambridge University combines scrap steel recycling with cement clinker production.

It uses recycled concrete as a flux rather than limestone.

Over the planned two-year trial period, the Cement 2 Zero project will investigate both the technical and commercial aspects of upscaling Cambridge Electric Cement production to produce 20 tonnes of the world’s first zero-emissions cement.

This will then be used in a construction project.

The project team involves academics from the University of Cambridge, and experts at Tarmac, Atkins, Balfour Beatty and the Materials Processing Institute, where the production and testing are taking place.
