CELSA Group transforms Nervacero’s the melting furnace to reduce the plant’s annual CO2 emissions by 10%


  • The intervention in the furnace of CELSA Group’s facilities in Nervacero will be financed by IDEA, as an investment to improve energy efficiency.

  • Currently the group already has one of the most sustainable steel production models, compared to most of the sector’s, since it uses electric arc furnaces, but works to eliminate emissions in the rest of the phases of the production process that still require the use of natural gas.


  • This initiative is part of the decarbonization plan that the company has underway, in which it has set itself the objective of reducing its scope 1 and 2 emissions by 50% in 2030 and being a Net Positive company in 2050.

    January 25th, 2023.- CELSA Group, a leading company in Europe in the manufacturing of circular and low-emission steel, has carried out the transformation of the melting furnace of the Nervacero steel mill (Basque Country), to make it even more efficient and reduce CO2 emissions derived from the smoke purification process which uses natural gas as energy.

    Thanks to the transformation of the furnace, Nervacero’s CO2 emissions as a whole will be reduced by 10% per year and natural gas consumption will decrease by 12% to 452Kw/t of steel produced.

    To this end, the company will request financing through the IDAE as an investment to improve energy efficiency.
    Nervacero’s electric arc furnace until now included a smoke purification system that consumed natural gas. After the investment made, the furnace will be similar to the ones that the Group has in the rest of its facilities in Spain, and that has a more environmentally sustainable scrap melting process.

    For the director of the Nervacero plant, Pablo Beitia, “the transformation of the furnace in our facilities is, without a doubt, a great step forward in the decarbonization objectives that the company has set, not just for Nervacero but for all of CELSA Group”. “Likewise, this initiative will help us improve energy efficiency, something really necessary today due to the increase and variability of energy prices,” adds Beitia.


    CELSA Group’s objectives: to be 100% circular and Net Positive

    The initiative to reduce emissions and improve efficiency in Nervacero is in line with the company’s strategy and its sustainability roadmap, which has set itself the objective of reducing its CO2 emissions (scope 1 and 2) by 50% by 2030 (compared to 2019 in CO2 intensity) and becoming a Net Positive company by 2050.

    Regarding its circularity objectives, CELSA Group expects to reach 98% circularity in 2030, and complete its circularity and be a Zero Waste company in 2050.
