CELSA Group will supply Acciona with circular and low-emission steel for the construction of the new airport in Palma de Mallorca


  • The company will supply corrugated steel produced through its circular and low-emission system, a production model that was key in Acciona’s selection, the company in charge of the works, which has prioritized a supplier capable of offering a product that contributes to reducing the carbon footprint of the installation.

  • The metals resulting from the demolition of the old terminal will be treated and delivered to CELSA Group, which will use them as raw material to produce the steel needed for the new facility, thus completing the circularity of the process.

  • Thanks to CELSA Group, the two sustainability objectives required by the manufacturer are achieved: to advance in circularity, since the steel obtained from the demolition will return to the airport in the form of new material, and to reduce CO2 emissions associated with the products used in the works, which in this case will be more than 40.


February 8th, 2023.- CELSA Group, Europe’s leading company in the manufacture of circular and low-emission steel, will produce and supply Acciona with the steel necessary to carry out the refurbishment and expansion works of the terminal and modules A and D of Son Sant Joan airport in Palma de Mallorca.

The company will supply the 7,000 tonnes of corrugated steel produced through the electric arc furnace system, that is, with low emissions, and from the use of metals resulting from the demolition of the old terminal completing a circular economy process.

The steel produced by CELSA Group has a better environmental performance, due to its circular origin and low carbon footprint. This will be possible thanks to the fact that the authorized manager in charge of the waste of the old Palma terminal will process the metals resulting from the demolition of the old terminal and supply it to CELSA.

CELSA will use this material to produce corrugated steel by electric arc furnace, in this case, powered exclusively with electricity of renewable origin, and will subsequently deliver the steel to Acciona that will use it in the construction of reinforced concrete structural elements in the reform and expansion of the new terminal.


Meeting decarbonisation and circularity objectives

In this way, two fundamental sustainability objectives are achieved. On the one hand, progress is being made in circularity in the use of materials contemplating the entire value chain, since the steel that is managed during the demolition will return to the airport in the form of material to be used in its remodeling and expansion. On the other hand, a notable reduction of more than 40% is achieved in the emissions associated with the product compared to the average of plants that produce with a similar technology in Spain. This means avoiding, as a result of this action, the generation of more than 1,900 tonnes of CO2 eq. emissions compared to the use of a conventional product.

This action is in line with ACCIONA’s positioning as a provider of sustainable infrastructure and renewable energy solutions and the various initiatives it carries out to reduce emissions associated with its supply chain. ACCIONA has already carried out similar initiatives to reduce emissions in works such as the construction of the CEIP Amanecer in Torrevieja or the reform of the Cartagena Arsenal.

About Acciona

ACCIONA offers sustainable infrastructure and renewable energy solutions worldwide. The company’s business strategy is aligned with those activities that the European Union’s Taxonomy of Sustainable Activities identifies as driving a decarbonized and sustainable economy. Thus, in 2021, 93% of ACCIONA’s eligible CAPEX was aligned with the demanding requirements of this standard.

ACCIONA has adopted absolute targets for reducing direct and indirect emissions in its activity, which the Science Based Targets (SBTi) initiative considers consistent with the objective of limiting the increase in global temperature to 1.5ºC, in line with the Paris Agreement. In 2021, scope 1 and 2 emissions were reduced by 19% and scope 3 emissions by 28% compared to the base year (2017), all in line with these science-based commitments.

The company has extensive experience in airport works. In Spain, he was responsible for the construction of the terminal building of the Adolfo Suárez airport in Madrid, the new runway of Malaga airport and the new terminal of Alicante airport. Abroad, it has executed works such as the runway of the new Western Sydney International Airport (Nancy Bird Walton), in Australia; the control tower of the new airport in Lima (Peru) or the expansion of Fiumicino Airport in Rome. The company also provides airport and handling services at various international airports.
