Critical Raw Materials and the Circular Economy

Critical raw materials are essential for the energy transition, digitalization, and industrial development. In a global context marked by geopolitical tensions, high levels of external dependence, and growing regulatory demands, the recovery of these materials has become a strategic challenge for Europe and for advanced economies.
 
Through its DDTP division, Técnicas Reunidas develops proprietary technologies that enable the recovery of key elements—such as rare earths, manganese, phosphorus, gallium, and metals found in batteries—from industrial waste, byproducts, or secondary sources. Our solutions combine efficiency, sustainability, and economic viability, driving circular economy models that strengthen strategic autonomy and reduce the environmental footprint. With a forward-looking vision, our technology helps ensure the supply of critical materials for the industries of tomorrow.

Técnicas Reunidas, through its In-House Technology Development Division (DDTP), has developed RARETECH®, a Spanish technology capable of recovering strategic elements essential to society’s technological progress and development in a way that is both economically viable and environmentally friendly.

Development of flexible technology that enables the recovery of manganese for the utilization of zinc ores whose manganese content makes them unmineable using conventional zinc extraction technology.

PHOS4LIFE® technology provides a method for recovering phosphorus in the form of phosphoric acid from incinerated sewage sludge ash.

RECYCLION® technology contributes efficiently and safely to the supply of critical metals in the industrial value chain for electric and connected vehicles (ECVs), promoting a sustainable model that is integrated into a circular economy and has a smaller environmental footprint.

GAXTRACT® technology is a hydrometallurgical solution designed for the selective recovery of gallium from byproducts and industrial streams. The metal obtained is used in high-value applications such as LEDs, integrated circuits, NdFeB magnets, and photovoltaic technologies.

The technology developed is designed to recover metals from waste photovoltaic panels, specifically: silicon (Si), silver (Ag), copper (Cu), and aluminum (Al) from the panels' cells.
