Recycling & Green Chemistry
Liten has set its sights on solutions to make the technologies being developed for tomorrow's low-carbon energy systems more sustainable. The institute is developing innovative processes capable of addressing new reserves of materials and, specifically, mining waste and spent electronic components. The goal is to recycle the most critical materials in such a way as to limit environmental impacts and, more broadly, address the entire value chain from design, extraction, and use to end-of-life, recycling, and reuse in low-carbon energy applications.
Liten researchers are synthesizing materials and developing eco-processes to meet the needs of the energy industry. Developments begin in the lab and are then scaled up to prepare for transfer to the market while ensuring compliance with applicable regulations.
Liten stands out for its capacity to develop recycling processes specific to spent renewable-energy components. However, the institute is also investigating new recycling channels for secondary materials leveraging its proprietary technologies.
At the same time, Liten is developing eco-design approaches for components that enable the best possible use of recycling processes.
Hydrometallurgical and supercritical water processes are currently in the lead, offering substantial advantages such as:
This research is conducted by a multidisciplinary team spanning chemistry, chemical engineering, electrochemistry, materials analytics, and materials science.
It is intended for:
The processes utilized at Liten are at TRL 3 to TRL 5 to facilitate scaleup and transfer.
CEA-Liten is leading efforts to develop a high-performance, economically competitive, and sovereign permanent magnet manufacturing industry in France. The recovery and recycling of critical materials will be one of its main pillars.
Plastics in multi-layer packaging can be particularly difficult to recycle. The CEA is engaged in the EU MERLIN project that aims at designing innovative solutions for recycling processes of these plastic materials. Its goal is to develop processes to reuse low-quality recycled polyethylene (rPE) from the delamination of rigid and flexible food packaging and recycled PET (rPET) from the delamination of flexible packaging.
Evidence of its commitment to the circular economy, CEA-Liten, a CEA Tech institute, has developed an environmentally-friendly and energy-efficient method for recycling end-of-life solar photovoltaic panels.

CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
