Mecaware at the heart of discussions on sustainable battery recycling at RS2E Day

On October 15, 2025, Mecaware took part in the "Recycling and Green Batteries" theme day organized by the RS2E network at Chimie ParisTech's Grande Bibliothèque. Mathieu Bordy, Laboratory Manager, together with Maxime Ducreux, Scientific Development Engineer, took the opportunity to present Mecaware's innovative approach to lithium-ion battery recycling.

‍

The event brought together a number of academic, industrial and institutional players committed to building a European recycling industry: IFPEN, ENS Lyon, ICGM, Ampère, Phenix, TIAMAT, Renault, Orano, as well as several leading research teams.

The ICGM and the Phenix laboratory are research teams, so perhaps this duplicates the end of the sentence.

Technical exchanges serving the same ambition: better recycling, useful recycling

‍

The day's events highlighted several trends that are shaping the industry:

• development of sulfate-free, more environmentally friendly processes;
• increased use of selective approaches and process modelling ;
• growing interest in direct recycling, especially for graphite;
• European regulatory pressure to meet 2031 targets and guarantee the integration of battery-grade recycled materials.

Mecaware's contribution: sulfate-free, flexible and circular technology

In this context, Mathieu Bordy presented Mecaware technology, based on sulfate-free CO₂ chemistry, enabling selective recovery of lithium, nickel, cobalt or even copper, in battery grade quality.

His speech also served as a reminder:

• the strategic challenges of European sovereignty over strategic metals ;
• l'importance de poursuivre la montée en pureté pour une réincorporation directe dans les nouvelles batteries; "montée en pureté" then "montée en puissance" next line, perhaps worded differently: "l'importance de poursuivre le travail avec les acteurs en aval pour la réincorporation des matériaux produits dans les nouvelles batteries"?
• Mecaware's industrial roadmap, with the ramp-up from the pilot plant to multi-site deployment, as close as possible to waste sources.

An ecosystem in motion, a role to play

‍

Mecaware's participation in this event illustrates the importance of working hand-in-hand with research and industry to build a new circular battery value chain in Europe. This collaborative dynamic will be decisive in securing materials, reducing the environmental footprint and supporting the development of truly sustainable electromobility.
