UK: Cambridge Electric Cement (CEC) has launched the two-year trial of its Cement 2 Zero project, aimed at scaling up production of its net zero-CO2, demolition waste-based alternative cement. It aims to produce 20t of the material for use in a low-impact construction project. CEC’s method, developed at the University of Cambridge, is based on the conversion of demolition waste into a slag-forming material within a steel furnace.
Developer Julian Allwood said “By combining steel and cement recycling in a single process powered by renewable electricity, we could supplement the global supply of the basic construction materials to support the infrastructure of a zero emissions world and to enable economic development where it is most needed.”
