The pour took place on EcoPark South, the first phase in North London Waste Authority’s plans to create a £1.2bn sustainable waste management hub and energy recovery facility at the existing Edmonton EcoPark.

The mix used on the project reduces the carbon footprint of the construction project by up to 70% when compared to traditional concrete.

Developed over four years using waste from steel slag Vinci Construction’s Exegy ultra-low carbon concrete has already been tested on several project in France but now makes its debut in the UK, where Taylor Woodrow is building a new flagship Resource Recovery Facility.

Nerissa Patel, project manager for Taylor Woodrow, said: “We are proud to have led the first use of Exegy ultra-low carbon concrete in the UK.

“Ultra-low carbon concrete is a key factor in our journey towards carbon neutrality and this marks an exciting step towards achieving it.”

Steve Crompton, director of Quality and Product Technology for Materials West Europe, Cemex, said: “We have been working with Vinci and Ecocem in France to investigate how alternative cement technologies can accelerate the reduction in CO2 in readymix concrete and are delighted to be involved with the project at Edmonton EcoPark to demonstrate how this new technology can contribute to ultra-low carbon emissions in concrete.”
