Sizewell C will reuse over 15,000 tonnes of recycled concrete from Sizewell A.

The concrete, sourced from the turbine alternator plinths at Sizewell A, has been repurposed following the demolition of the turbine hall as part of the older site’s ongoing decommissioning led by Nuclear Restoration Services.

After rigorous safety testing, the recycled materials have been transported a short distance to Sizewell C’s Main Construction Area, where they will be used as sub-bases for various foundation platforms.

The collaboration between Sizewell A and C reduces the need for newly mined aggregates, cutting both costs and carbon emissions. Additionally, reusing this material lessens the number of trucks transporting aggregate through East Suffolk.

Damian Leydon, Site Delivery Director for Sizewell C, highlighted the project’s environmental impact.

"By reusing this material, we’re reducing the number of trucks transporting aggregate through East Suffolk, while further reaffirming our commitment of minimising our environmental impact during construction," Leydon said.

This innovative approach marks a significant shift towards sustainable construction, ensuring that existing resources are effectively utilised with minimal waste.
