CELSA Group launches the HYMET project to promote the recovery of its waste with renewable hydrogen

  • The group currently recovers more than 90% of the waste it generates in its steel production process and will reach 100% by 2025.
  • The company will allocate about 2 million euros in the development of the project and has a grant of 1.2 million from the Center for Industrial Technological Development (CDTI).
  • The initiative allows to accelerate the implementation of the “Innovation and Sustainability Plan” to promote the circular economy and reduce CO2 emissions, which CELSA Group has in place.


Barcelona, 13 de julio de 2022.- CELSA Group, a leading company in Europe in the manufacture of circular and low-emission steel, has launched the HYMET project that aims to study new technologies applicable in the steel industry for the revaluation of by-products of the process itself and decarbonization through the use of renewable raw material, like hydrogen.

The HYMET project has an estimated total budget of 5.8 million euros and has been supported by the Centro para el Desarrollo Tecnológico Industrial (CDTI) through the MISIONES call and has a grant of 3.9 million euros. CELSA Group’s investment is of about 2 million euros and the company receives a grant of 1.2 million euros from the CDTI.

HYMET proposes the study and technological maturation of innovative solutions in three vectors of the future for decarbonization and industrial circularity such as: the recovery of industrial waste (husk that is produced in rolling mills, mainly) through an innovative reduction reactor that uses renewable reducing agents;  the generation of green hydrogen through high efficiency electrolysis technologies and finally, the study of CO2 capture and its integration again through electrolysis technologies for the generation of synthesis gas.


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

CELSA Group’s strategic objectives are to achieve complete circularity in the next five years and become a Net Positive company by 2040, ten years ahead of the European Union’s decarbonization forecasts.  For this reason, for the circular steel production company, which currently generates around 70,000 tons/year of various by-products in its production process in Spain, of which about 90% are valued, HYMET opens a potential way towards its objectives in the medium and long term.

After a first phase of study and technological maturation, CELSA Group will continue to invest efforts until the industrial deployment of the results obtained with this project.


Consortium that promotes the project

This initiative has been promoted by a group of leading companies in each of the technologies under study: TÉCNICAS REUNIDAS S.A., AMES PM TECH CENTER SAU, ARIEMA Energía y Medioambiente, S.L. and AE S.A.

To strengthen greater chances of success in development, HYMET has the participation of important technological centers, leaders in the sectors covered by the project, such as the Institut de Recerca en Energia de Catalunya (IREC), various centers attached to the Consejo Superior de Investigaciones Científicas (CSIC), such as the Instituto de Tecnología Química (ITQ),  the Instituto de Cerámica y Vidrio (ICV) and the Laboratorio de Investigación en Fluidodinámica y Tecnologías de la Combustión (LIFTEC), as well as the University of Huelva (UHU).


About CELSA Group

CELSA Group is Europe’s leading producer of low-emission, circular steel. It recycles ferrous scrap to produce steel in electric arc furnaces, the most sustainable system in existence. Its integration throughout the steel value chain makes it a circular reference company.

It has more than 120 workplaces in the world and generates direct, indirect, and induced employment for more than 70,000 professionals. Annually it recycles 8 million tons of ferrous scrap that it destines to the production of steel, and also contributes to the recycling of another 1.5 million tons of materials, thus avoiding the accumulation of waste in landfills and obtaining again products of high value for society, avoiding the use of natural resources. The company is made up of 6 business groups with steel mills, rolling mills, processing plants, distribution companies and recyclers.
