Metso secures engineering contract for Rio Tinto’s BioIron process

Rio Tinto is planning to test the BioIron process on a larger scale at a specially designed continuous pilot plant.

Rio Tinto has awarded a design and engineering contract to Metso for a continuous pilot plant (CPP) for the BioIron process.

A low-carbon iron-making process, BioIron uses ore sourced from mines in Pilbara, Australia. It involves raw biomass, an alternative to metallurgical coal, as a reductant and microwave energy.

This will convert iron ore to metallic iron in the steelmaking process.

Rio Tinto is planning to test the BioIron process on a larger scale at a specially designed CPP, which will have a capacity of one tonne per hour, to help decarbonise the steel value chain.

Under the contract, Metso will undertake the detailed design work of the CPP’s reduction furnace and certain other equipment for the BioIron process.

The contract builds on the companies’ joint work developing the BioIron process, for which effectiveness has been successfully demonstrated during small-scale pilot tests carried out at Metso's Research Centre in Frankfurt, Germany.

Rio Tinto steel decarbonisation general manager David Leigh said: “This work is the key next step in the development of the BioIron technology and builds on the success of the research and development team.”

Metso Ferrous director Matthias Gabriel said: “We are very excited to continue the close working relationship with Rio Tinto and to provide engineering and design support as we move to the next phase of development of the BioIron technology.”

ESG 2.0 marks a shift towards stricter environmental rules

ESG is moving into a different era, which we call ESG 2.0. While ESG 1.0 was driven by voluntary corporate action, spurred by pressure from activist consumers and investors, ESG 2.0 is being driven by a new wave of government policies. The EU has taken the regulatory lead, with rules introduced or in the pipeline that will price emissions, regulate the use of the terms ‘ESG’ and ‘sustainability’ in marketing materials, and make ESG reporting mandatory. The US has taken a different approach, favoring less regulation and more financial support in the form of tax breaks for clean industry (renewables plus nuclear and hydrogen). China is planning to expand its emissions trading system to more sectors, decarbonize its heavy industry, and ramp up its use of renewables. The new policy direction is mainly motivated by the ambition to hit net zero emissions targets. But on top of this, governments are now competing for clean industry and trying to challenge China’s leadership on the production of the world’s green technologies such as solar panels and batteries, as well as the production and refinement of materials needed for energy transition such as lithium. These driving forces are leading to policy that will impact every sector, not just heavy industry, and will keep ESG near the top of the regulatory agenda over the longer term.
