Radioactive recycling


The RECUMO facility transforms radioactive residues into reusable raw materials.

From 2026 onwards, the nuclear research centre SCK CEN will transform radioactive residues into low-enriched uranium and will purify them in its brand new RECUMO facility. These residues resulting from the production of medical radioisotopes on the site of the Institut National des Radioéléments (IRE)

Belgium is amongst the world’s elite in nuclear medicine. It owes its reputation to the Belgian Nuclear Research Centre (SCK CEN) and the Institut National des Radioéléments (IRE). This dynamic duo is behind a quarter of the global production of medical radioisotopes. These are radioactive particles used to detect and/or treat cancers, heart diseases and other illnesses.

RECUMO guarantees the security of supply of medical radioisotopes around the world.

“We have been producing them for more than 50 years, that is to say five decades of making a difference for millions of patients. To keep fulfilling this public health role, we needed a structural solution for radioactive residues resulting from the production process.”
Erich Kollegger, IRE CEO

Circular economy

In practical terms, the nuclear research centre SCK CEN will transform radioactive residues into low-enriched uranium and will purify them. The goal is to recover uranium so that this high-quality material can be reused.

“We are giving a second life to these radioactive residues. They become reusable raw materials that can be used as fuel for research reactors or as ‘targets’ for the production of new radioisotopes" - Peter Baeten, SCK CEN director-general.

State-of-the-art technology

For the purification process, RECUMO uses state-of-the-art radiochemistry technology. This is not the first time that SCK CEN has made use of this technique. In the 1980s, it was already performed in laboratories. Today, IRE and SCK CEN have developed, optimised and fine-tuned it. In 2020, we could apply it on a semi-industrial scale.

The construction of a European first

In March 2022, the competent authorities have officially approved this project. The Federal Agency for Nuclear Control (FANC) has granted the establishment and operating permit, while the Flemish Region has issued the environmental permit. In February 2023, the two project partners launched the ground-breaking ceremony.

Completion of RECUMO building: 2025

Belgium is the only country in Europe that will have such a unique facility. The completion of the facility is planned for 2025. Shortly after that, SCK CEN will commission the facility and start purifying the residues. The facility will be processing the current residues and those resulting from the production until 2038. These residues come from IRE in Fleurus.


A watchful eye

The RECUMO project of SCK CEN and IRE is being implemented in close cooperation with the Directorate-General for Energy of the FPS Economy, SMEs, Self-employed and Energy, and under the supervision of the Federal Agency for Nuclear Control (FANC), Euratom and the United States. They impose safety and security standards and carry out checks to ensure that these are strictly complied with.
