Less than half the carbon of conventional clinker, at the same price

Buyers of cement need three answers before switching: how much carbon it saves, what it costs, and whether there will be enough of it. This page sets out what we can share today and what is in the data pack.

The numbers we stand behind

>50%

Lower emissions than conventional cement from the first commercial tonnes, with further reductions expected as production scales.

Parity

Cost parity with conventional cement. Lower carbon without a green premium for the buyer.

Reclinker

~7%

Share of global CO₂ emissions caused by cement, roughly three times aviation. Most of it comes from clinker.

Where the saving comes from

In a conventional kiln, CO₂ comes from two places: limestone releasing it as it is heated, and the fuel used to heat it. Reclinker removes both from the clinker step.

No limestone

Our raw material is cement paste that has already been made once. No rock is quarried and none is calcined.

No fossil-fuel heat

The heat comes from an electric arc furnace that is already melting scrap steel. As the grid gets cleaner, so does our clinker.

No new kiln

The furnace already exists. We add separation and milling around it rather than a kiln line.

Two products, one melt

The same furnace run that makes our clinker also makes recycled steel, using cement paste in place of lime flux.

From thousands of tonnes to hundreds of thousands

Thousands of tonnes have been produced at 7 Steel UK in Cardiff and the first commercial sales are secured. The Series A funds the move to full commercial production in South Wales.

Now

First commercial sales from Cardiff, with milling through toll partners in South Wales.

2026 to 2027

Our own pilot milling plant, and processing scaled from thousands to hundreds of thousands of tonnes a year.

Next

Replication at electric arc furnace sites in Europe and the United States, using a standardised, repeatable plant design.

Large concrete users have signalled through the Innovate UK Advance Market Commitment that they plan to buy more low-carbon materials over the next five years.
