Questions and answers

Frequently asked questions.

Short answers about Greensteel UK, the mill and its steel.

What is Greensteel UK?

Greensteel United Kingdom (Greensteel of United Kingdom Limited) is developing a new electric arc furnace steel mill in the UK. It will make low-carbon structural sections, round bars, sheet piles and angles, principally from recycled UK steel.

When will Greensteel UK produce steel?

First steel is planned for 2029. The site will be announced shortly, followed by consents, investment and construction.

Where will the steel mill be built?

The site will be announced shortly. Locations across the UK have been assessed for grid power, water, rail access and a skilled workforce.

What will the mill make?

A proposed range of universal beams and columns, parallel flange channels and angles; round bars; and sheet piles. They are used in buildings, bridges, railways, flood defences, wind turbines, transmission towers and solar farms.

How will the steel be made?

Recycled UK steel is melted with electricity in an electric arc furnace, then refined, cast and reforged into new sections. There is no blast furnace and no coke ovens.

Why is electric arc furnace steel lower carbon?

World Steel Association global averages for 2024 put electric arc furnaces running on recycled steel at 0.71 tonnes of CO2e per tonne of crude steel, against 2.66 tonnes for the blast furnace route: around 73% less.

Can the furnace run on renewable power?

Yes. The furnace is designed with the latest power electronics, which draw a smooth, steady load and allow it to run on electricity from wind, solar and storage.

How many jobs will the mill create?

Hundreds of skilled jobs at the mill, and many more in construction and the supply chain, with apprenticeships and retraining for new and experienced steelworkers.

What is a steel passport?

A digital record for every product: where it was made, what it was made from, its certificates and its verified emissions, ready for embodied carbon reporting.

How does the project support the UK Steel Strategy?

It adds UK steelmaking capacity through electric arc furnaces, the route the Strategy sees as the most viable for decarbonised production, recycles UK steel at home and creates skilled jobs.
