Phytoremediation gardens at Chimex
Sustainable development

Through the use of photoremediation gardens, the Chimex subsidiary's "100% clean water" project makes it possible to treat wastewater so effectively that it can be returned to the natural environment.

Phytoremediation gardens at Chimex


Today the "100% clean water" project makes it possible to treat the wastewater from a Chimex factory so effectively that it can be returned to the natural environment. A first for the chemical industry! "And what's so amazing is that the project was thought up by one of the factory employees," says Chimex Operations Director Karine Melloul. "We have now successfully completed phase one of the operation. Soon this innovative solution should make it possible, through the phytoremediation gardens (phytoremediation is a group of technologies using the bacteria that develop around plants as the main treatment agent) to restore wastewater to the natural environment, and to function in a closed circuit, re-using the water."

This means real savings in water consumption. Inaugurated in October 2011, the phytoremediation gardens at Mourenx enable savings in basic resources like water, while preserving the social aspects and landscapes of sites where the technology is set up. Above all, they represent the hope of cleaner, more responsible chemicals.

Chimex, L’Oréal's French subsidiary, specialised in the production of cosmetic ingredients using chemistry and biotechnologies, is a perfect example of environmental innovation and performance in the use of water. Six years of studies were needed to combine a physicochemical system with treatment by phytoremediation.
