Reju is a textile-to-textile regeneration company created within Technip Energies, focusing on polyester waste as feedstock for circular materials. It operates from the Paris region and markets “regeneration hubs” as industrial sites that convert end-of-life textiles into inputs for new polyester production.

What it does

Reju develops chemical regeneration pathways for polyester, emphasizing traceable, high-quality outputs aimed at re-entering mainstream textile manufacturing. The company frames its work around infrastructure buildout and policy alignment for circular textiles.

Recent projects

Reju opened “Regeneration Hub Zero” in Frankfurt in October 2024 as an early facility and, in May 2025, announced the Chemelot Industrial Park in Sittard (Netherlands) as the site for its first industrial-scale regeneration center (“Regeneration Hub One”).
