MAXIBROME, Séché Environnement's innovative bromine regeneration process

Since 2015, the TREDI site in Saint-Vulbas (a subsidiary of the Séché Environnement Group) has been pioneering a process for regenerating bromine-bearing brines. This technology is capable of recovering up to 99% of the bromine contained in this waste, which is considered to be hazardous and was previously destroyed through incineration. This waste is transformed into bromine, which can be reused directly by the chemical and pharmaceutical industries.

Maxibrome: more regenerated bromine with fewer CO₂ emissions!

The TREDI Saint-Vulbas teams are now going one step further. By adding oxygen during the combustion phase, Maxibrome can now boost the site’s regenerated bromine production capacity by 60%.

Maxibrome has given TREDI Saint-Vulbas world leadership status in bromine regeneration.

A circular economy loop

Expertise in this circular economy loop will help:

• Avoid the extraction of a rare natural resource, which is usually sourced from the Dead Sea region
• Increase French and European sovereignty by reducing dependence on a predominantly imported material
• Lower water consumption, since Maxibrome uses up to 3,000 times less water on average than virgin bromine production
• Rein in greenhouse gas emissions; producing one ton of regenerated bromine emits 20 times less CO₂ on average than producing one ton of virgin bromine

This unique expertise in Europe is contributing to efforts aimed at decarbonizing the chemical and pharmaceutical industries.

Strengthening industrial sovereignty

Now capable of fulfilling nearly one third of national demand with its regenerated bromine, the TREDI site in Saint-Vulbas offers a secure local solution for supplying this chemical element, which is essential to many industrial processes. As such, Maxibrome is playing a role in reinforcing industrial expertise in France and Europe.

“Maxibrome perfectly reflects our expertise in the circular economy. Manufacturers can now harness the resources in their waste and incorporate them into their manufacturing processes. By producing regenerated and decarbonized local resources, Séché Environnement is helping protect natural resources, promote industrial relocation and create a net-zero economy,” explains Maxime Séché, CEO of the Séché Environnement Group.

This new industrial innovation bears testament to a €12 million investment and is fully in line with the circular economy strategy and environmental protection approach that define the Séché Environnement Group’s DNA.
