Técnicas Reunidas participates in the CHAINERGY project to reduce dependence on critical raw materials and strengthen European energy autonomy

• CHAINERGY will research new materials and advanced processes for energy storage and generation, promoting the circular economy and the recovery of strategic resources.
• The project is funded by the Center for Technological Development and Innovation (CDTI) and is supported by the Ministry of Science, Innovation, and Universities through the Science and Innovation Missions 2025 program.
 

The main objective of the project is to develop sustainable technological solutions that reduce dependence on critical raw materials (CRMs) and advance toward a more resilient energy transition. 

CHAINERGY was launched in response to the challenges posed by the Critical Raw Materials Act (CRMA), adopted by the Council of the European Union (EU) in March 2024. 

This regulation sets ambitious targets for 2030; including extracting at least 10% of critical raw materials within the EU, processing 40% locally, and recycling a minimum of 25%, thereby reducing dependence on third countries and strengthening European strategic autonomy.

In this context, CHAINERGY aims to develop new active materials and devices for energy storage and generation, promote phosphorus recovery processes, and improve recycling technologies for end-of-life lithium-ion batteries. All of this is done with the aim of maximizing the value of available resources, reducing dependence on scarce materials, and promoting circular economy models.

CHAINERGY will investigate alternative materials—such as magnesium and manganese silicides—which are abundant, cost-effective, and have a low environmental impact, for the production of thermoelectric generators (TEGs), replacing bismuth, tellurium, or lead, which present economic, geopolitical, and environmental limitations. In this way, it will contribute to strengthening the EU’s position in a technology that is fundamental to various industrial sectors, such as the automotive and aerospace industries, within a global market projected to exceed $1.4 billion by 2030.

The project also focuses on new dry synthesis routes to develop advanced battery materials, reducing waste generation and replacing critical materials, such as cobalt or lithium, with more readily available alternatives.

As part of the CHAINERGY project, Técnicas Reunidas will drive the development of technologies for phosphorus recovery from sewage sludge and agro-industrial waste, generating high-value-added products that promote the circular economy and reduce geopolitical dependence on phosphorus, an objective considered strategic.

In addition, CHAINERGY will develop advanced technologies for safe disassembly and automatic sorting, using computer vision and computed tomography to efficiently and sustainably access the valuable materials present in batteries, which will improve recycling processes and traceability.

CHAINERGY is led by the company HI IBERIA and includes the participation of Técnicas Reunidas, Ferroglobe, Empresarios Agrupados, RIMSA, and AUTLAN. Several leading technology centers (LEITAT, CENIM, CIAE, and ICMM-CSIC) are also collaborating on the project, contributing complementary scientific expertise. The joint efforts of all these entities will ensure that the anticipated challenges are addressed comprehensively.

The project will last four years and has a total budget of €5,264,910, to which Técnicas Reunidas is contributing €1,222,876. 

In summary, CHAINERGY represents a strategic commitment for Spain and for the EU as a whole, as it will contribute to achieving a more sustainable, competitive, and resilient energy transition, based on innovation, the circular economy, and the reduction of external dependencies.

Técnicas Reunidas leads PERMANET to boost the circular economy in rare earths

The European PERMANET project is making progress in developing innovative solutions to improve the recovery of critical raw materials from electronic waste and industrial materials, helping to reduce Europe’s dependence on imports and strengthen its strategic autonomy.

In a recent interview, Peter Fleming Rubio, PERMANET Project Coordinator representing Técnicas Reunidas, highlighted the company’s key role as project coordinator, leading its overall implementation, governance, and alignment with European Commission and industry standards. He also emphasized the importance of comprehensive management to ensure quality, risk mitigation, and the project’s long-term impact.

In addition to its coordination role, Técnicas Reunidas leads Work Package 3 – Hub 1, focused on the sustainable supply of rare earths. In this area, it is driving the development and scaling up of its proprietary RARETECH™ technology, aimed at producing rare earth carbonates and oxides from monazite concentrates sourced from various sources, including primary deposits and secondary materials. This process yields commercially viable products free of radioactive components, contributing to a safer and more sustainable supply chain.

PERMANET is structured around three technology hubs covering the entire value chain: from the sustainable supply of rare earths, through circular innovation in recycling, to the advanced production of magnets and their validation in industrial applications such as electromobility, energy, and industrial equipment.

The project stands out for its comprehensive approach, which combines research, technological development, and industrial scaling, with the aim of establishing a resilient and circular European value chain centered on rare earth permanent magnets.

Técnicas Reunidas’ participation and leadership reinforce its position as a key player in the development of technological solutions for the challenges associated with critical raw materials and the transition toward a more sustainable economy.

Técnicas Reunidas leads the project that will create the first European value chain for the production of permanent magnets

  • The project, known as PERMANET, is of great strategic importance for addressing the European Union’s (EU) weakness in the manufacturing of products that are essential for digitalization and the energy transition.
  • Its goal is to increase the EU’s annual production capacity for permanent magnets twentyfold by 2050.
  • It will be carried out by 34 partners, including companies, research centers, clusters, and universities.
  • The manufacture of permanent magnets requires access to technologies for the production of rare earth elements, an area in which Técnicas Reunidas has extensive experience and technological solutions that it already supplies to the market.

 

Técnicas Reunidas has been designated as the lead company for the PERMANET Project (PERmanent MAgnet Network for the European Transition), promoted by the European Commission (EC) under its Horizon Program, whose objective is to create the first complete European value chain for the production of permanent magnets.

This chain will include the extraction, processing, and refining of rare earths, which form the basis for the production of permanent magnets; the manufacture of the magnets themselves; and their subsequent recycling.

In addition to leading the project, Técnicas Reunidas will undertake, at its Technology Center, the development of technology that will enable the production of rare earths from minerals and secondary sources for subsequent use in the manufacture of permanent magnets.

The company has proven experience in this field, as it already supplies its own technology, RARETECH, to the market, which enables the production of rare earth concentrates in the form of carbonates from minerals.

Strategic Value and Geopolitical Risk

This is a project of high strategic value, as permanent magnets are a fundamental material for the manufacture of more than 200 product groups that are essential for digital development and the energy transition, particularly for the manufacture of motors for electric vehicles, wind generators, and transformers.

Furthermore, they are subject to high geopolitical risk. Currently, EU production of permanent magnets is extremely low, barely reaching 1,000 tons per year, and is not expected to cover more than 20% of European needs by 2030. Increasing this capacity would require a sharp rise in rare earth imports from China, the world’s leading producer, which currently supplies virtually all of the EU’s demand for these materials.

This excessive dependence on China could become even more serious in the near future, due to the growing demand for permanent magnets to drive the electrification required by the energy transition and the recent decision by Chinese authorities to restrict the export of rare earth processing technologies.

For this reason, the EC approved a Critical Raw Materials Act last year, the regulations for which were established last March, “as demand for rare earths is expected to increase exponentially in the coming years.”

A strong boost to the production of permanent magnets

The PERMANET project is part of this effort to overcome the limited production capacity and weak development of certain segments currently affecting the EU’s permanent magnet production value chain.

The project aims to increase European production of permanent magnets to 2,800 tons per year by 2037, 7,800 tons by 2040, and 21,600 tons by 2050, which would already cover nearly 50% of the EU’s needs in that year.

To this end, the project involves 34 partners (17 large companies, seven SMEs, four research centers, two universities, and four clusters from a total of eleven European countries) and will have a budget of approximately 21 million euros, with a grant of nearly 16 million. It is estimated to last 40 months.

Javier Limpo, director of the In-House Technology Development Division at Técnicas Reunidas, emphasized that “this project, which is essential for advancing European independence in the field of energy transition, will strengthen Técnicas Reunidas’ position as a technological leader in the extraction and recovery of rare earth elements.”

Australia’s St George Mining hires Técnicas Reunidas to process rare earths in Brazil

• The two companies have entered into a strategic engineering partnership under which Técnicas Reunidas will conduct processing tests on high-concentration rare earths at the project being developed by St. George Mining in Araxá, a municipality in the state of Minas Gerais.
• Araxá is the largest hard-rock rare earth deposit in South America and one of the largest in the world.
• Técnicas Reunidas will contribute its proprietary technology, called RARETECH®, to the project, which enables the production of rare earth concentrates in the form of carbonates from ores.
• At the end of last February, the Spanish company also reached an agreement with the Australian firm Osmond Resources to provide RARETECH® technology for the European Union’s first comprehensive rare earth production project, which is being developed in Jaén.
• RARETECH® is part of Técnicas Reunidas’ portfolio of proprietary technologies for the recovery of critical raw materials, rare earths, and other products that the Spanish company has already supplied or submitted for bidding in the United States, Japan, Austria, Switzerland, Australia, Spain, South Africa, Brazil, and Turkey.
 

The Australian company St George Mining Limited has announced the signing of a memorandum of understanding (MoU) with Técnicas Reunidas under which it will contract the Spanish company to conduct sample processing tests at the rare earth deposit in Araxá, a town in the Brazilian state of Minas Gerais.

St George Mining is the 100% owner of this high-grade niobium and rare earths deposit, which is the largest hard-rock deposit in South America and one of the largest in the world. In fact, it is also larger than the main rare earths mine in the U.S., located in the California town of Mountain Pass.

The Australian company, which specializes in developing critical mineral recovery projects, has described the agreement as a “strategic engineering partnership to access cutting-edge European rare earth processing technology.” In particular, it has highlighted the proprietary technological solutions that Técnicas Reunidas has developed for the recovery of critical materials and, more specifically, the fact that it is the lead company in the EU-funded PERMANET project, which aims to create the first European value chain for the manufacture of permanent magnets.

Scope of Técnicas Reunidas’ work

The initial scope of the work to be carried out by Técnicas Reunidas will consist of applying RARETECH® technology for the refining of rare earth mineralization, including the production of mixed carbonate and rare earth oxides, and for the separation and fractionation of rare earth elements.

Additionally, there is a possibility that St George Mining may request additional work from Técnicas Reunidas, which would include the design of a flow diagram and an industrial plant for rare earth processing operations, among other tasks.

St George Mining, which already has its Brazil project in an advanced stage of development and has half a dozen more in Australia, has emphasized that the engagement of Técnicas Reunidas has the potential to open European markets to Araxá’s rare earths and joins the strategic alliances the Australian company has already signed with REalloys in the U.S. and with MagBras in Brazil.

John Prineas, CEO of St George Mining, stated that “we are very excited to work with Técnicas Reunidas to further evaluate the optimal processing route for Araxá’s rare earths, as their reputation and experience in this type of activity is unmatched.”

Técnicas Reunidas’ proprietary technologies for the recovery of critical materials

It is worth noting in this regard that, at the end of last February, the Spanish company also reached an agreement with the Australian firm Osmond Resources to provide RARETECH® technology for the European Union’s first comprehensive rare earth production project, which is being developed in an area of over 220 square kilometers located in the north of the province of Jaén.

RARETECH® is part of the wide range of technological solutions that Técnicas Reunidas has developed, through its In-House Technology Development Division and its Technology Center, for the recovery, processing, and refining of critical minerals and essential metals, as well as other products generated through the circular economy. These in-house technological solutions are already implemented or are being bid on in markets in the United States, Japan, Austria, Switzerland, Australia, Spain, South Africa, Brazil, and Turkey, among other countries. 

In addition, the company actively participates in the development of national and international projects related to critical raw materials, particularly within the framework of the Misiones Programs of the Center for Industrial Technological Development (CDTI) of the Ministry of Science, Innovation, and Universities, and the Horizon program of the European Union.

Técnicas Reunidas promotes the SINCER project to recover base metals from metallurgical waste

• The project stems from the need to explore new methods and processes for the processing, recovery, and recycling of key metals from mixed industrial waste generated by the metallurgical industry, which is currently discarded.
• SINCER is funded by the Center for Technological Development and Innovation (CDTI) and supported by the Ministry of Science, Innovation, and Universities through the Science and Innovation Missions 2025 program. 
 

Last January, activities began on the SINCER project (Industrial Symbiosis for Circularity and the Economy of Critical Raw Materials), whose purpose is to investigate the recovery of critical metals present in industrial waste from various sources generated by the metallurgical industry.

Its main objective is to promote effective industrial symbiosis through research into sustainable technologies aimed at the recovery and valorization of essential metals, such as manganese (Mn), silicon (Si), magnesium (Mg), nickel (Ni), or chromium (Cr), and key metals, such as zinc (Zn) or iron (Fe), present in such waste.

In particular, the project aims to close material cycles and facilitate their reincorporation into both the original processes and new strategic applications; for example, in batteries, magnets, and alloys. 

The project is being carried out by a consortium led by the company FERROGLOBE, which coordinates the work of five other companies: Técnicas Reunidas, SIDENOR, AUTLAN, Magnesitas Navarras, and Semantic Systems. Nine research organizations are also participating: GAIKER, CTC, CETIM, Idonial, Tecnalia, Leitat, the University of Barcelona, the University of Navarra, and Lurrederra. 

SINCER will generate viable processes that will enable the companies in the consortium to recover and purify elements contained in byproducts that currently have no commercial outlet, converting them into reusable raw materials and thereby reducing their external dependence on raw materials in their production processes.  

Specifically, the plan is to recover up to nine waste streams from the operations of four industrial partners in the consortium (FERROGLOBE, SIDENOR, AUTLAN, and Magnesitas Navarras). For its part, Semantic Systems, a technology company specializing in industrial Artificial Intelligence (AI) and blockchain solutions, is responsible for designing an interoperable digital ecosystem that enables full traceability of the value chain.

To achieve its objectives, SINCER will combine hydrometallurgical and pyrometallurgical processes, along with advanced conditioning and separation technologies, in order to maximize resource recovery and improve the circularity of strategic raw materials. These activities will be led by Técnicas Reunidas, which has extensive experience in these processes and technologies. 

The project will last four years and has a total budget of €7,333,603, to which Técnicas Reunidas is contributing an investment of €2,039,289. 

Ultimately, SINCER will help consolidate a robust circular economy centered on critical raw materials, helping to reduce external dependence and generating high-value scientific and technological knowledge for industry.
