Técnicas Reunidas contributes to SERVET project to recover strategic raw materials

The project investigates advanced technologies for recovering copper, silicon, tantalum, niobium, silver, and tin from consumer waste and complex industrial waste.
It is funded by the Center for Technological Development and Innovation (CDTI) and the Ministry of Science, Innovation, and Universities under the Science and Innovation Missions program for the 2025 call for proposals.
 

The SERVET project (Research on New Circular Economy Processes in the Service of Strategic Sovereignty) helps address one of the most significant strategic challenges for the European Union and, more specifically, for Spain: ensuring secure and sustainable access to certain critical and strategic raw materials (CRMs) through the recovery of waste from consumer products and complex industrial streams that currently lack an efficient recovery pathway.

To this end, it proposes the design of a new circular, efficient, sustainable, and technologically advanced value chain, based on the selective recovery of strategic materials present in waste such as photovoltaic and hybrid panels, printed circuit boards (PCBs), end-of-life vehicle (ELV) fluff (ELVs), steel mill slag, and other complex solid industrial waste. 

The project focuses particularly on the recovery of copper (Cu), silicon (Si), tantalum (Ta), and niobium (Nb), elements that are essential for the energy transition, digitalization, the automotive sector, and the electronics industry. 

It will also investigate the recovery of silver (Ag) and tin (Sn), metals of high industrial value, in order to maximize the economic viability and overall efficiency of the process and thus contribute to strategic sovereignty in alignment with Mission 5 of the Misiones program call for proposals.

To achieve its objectives, SERVET will integrate disruptive technologies to ensure advanced and sustainable recovery through a systemic and interdisciplinary approach that will combine a wide range of activities: advanced pretreatments; intelligent conditioning and sorting of post-consumer waste; selective hydrometallurgical technologies for the extraction of CRMs from complex waste matrices; pyrometallurgical processes to recover critical raw materials from secondary fractions; and online analysis systems using advanced optical technologies (RGB, HSI, LIBS, NIR, Raman) with artificial intelligence algorithms for real-time characterization and quality control.

These technologies will enable the reintroduction of recovered materials into new high-value applications, such as hybrid solar panels or functional conductive inks, thereby closing the full circularity cycle.

The SERVET project is being carried out through a consortium led by the company FRAGNOR (TRADEBE), which coordinates the work of five other companies: Técnicas Reunidas, Atlantic Copper, Abora Energy, LENZ Instruments, and INM (Ingeniería Navarra Mecánica). Four leading technology centers (GAIKER, EURECAT, LUREDERRA, and CENIM-CSIC) are also participating, contributing advanced scientific capabilities in analysis, characterization, and pilot validation. 

The project will last four years and has a total budget of €6,013,229.00, to which Técnicas Reunidas is contributing €1,587,069 to develop hydrometallurgical processes that enable the recovery of Ag, Si, and Cu from a combination of silicon dust waste from solar panel recycling and PCB powder. 

SERVET will have a significant impact on industrial and regional ecosystems by recovering complex waste, preventing its accumulation, and reducing environmental risks, while increasing the efficient recovery of critical raw materials, thereby reducing dependence on imports. All of this is fully aligned with several of the UN’s Sustainable Development Goals (SDGs)—innovation, sustainable industry, climate action, quality employment—and with reindustrialization and the creation of skilled jobs in regions with low industrial density.

Consequently, thanks to its comprehensive and multidisciplinary approach, SERVET will contribute to strengthening the strategic autonomy of Spain and the European Union as a whole in critical sectors, fostering a fairer, more resilient, and more inclusive economy.
