LIBERTY Steel UK successfully trials ecoke to reduce CO2 emissions

In a major step forward in its decarbonisation journey, LIBERTY Steel UK has successfully completed trials of ecoke. The trials open up significant opportunities both for LIBERTY’s business and potentially for the broader steel industry globally. 

What is ecoke and why does it matter?

Ecoke is a sustainable new raw material that can replace anthracite, the main source of charge carbon in electric steelmaking. This means it has the potential to reduce steel’s carbon footprint by as much as 30%. 

Another benefit to this replacement is that it comes with no downsides to the production process. The ecoke briquettes are delivered to site in similar packaging to the anthracite and ecoke is charged into the electric arc furnace in the same manner as the anthracite via the scrap basket.

In addition to the environmental benefits, this could also result in substantial economic benefits too through the reduction in carbon credits.

How did the team achieve this?

The steelmaking team at Aldwarke Cast Products (ACP) in Rotherham performed a review of the processes to identify opportunities to reduce its CO2 emissions. The team identified anthracite as the main source of charge carbon in electric arc furnace production – accounting for between 86 and 97%. 

A steering team was formed in Rotherham to replace anthracite with environmentally sustainable alternative. The group considered all available options and finally identified CPL Industries as local supplier of a biofuel called ecoke.

Scott Jackson, Plant Manager at ACP of LIBERTY Speciality Steel said: “The success of LIBERTY’s ecoke trials is a major step forward for our GREENSTEEL strategy. The major reductions in CO2 emissions ecoke enables, without any downside to the production process, can help to further decarbonise our production and the wider steel industry.”

The ecoke initiative is part of LIBERTY’s drive to lead transformation of steel manufacturing through its GREENSTEEL strategy. Production at LIBERTY’s electric arc furnace in Rotherham generates just 10% of the direct emissions compared with traditional coal-based blast furnaces which produce the vast majority of the UK’s steel output.
