Ahlstrom, a supplier of high-performance, fiber-based materials, received the French trophy of the Ecological and Economical Technologies for its photocatalytic filter media utilized in what is said to be the first anti-odor building for the storage of sludge. The competition was organized by ADEME (French environment and energy control agency), and the prize was presented during Pollutec Horizons 2007, held in Villepinte, France.

The modular anti-odor building comprises an Ahlstrom filter media integrated in the flexible wall structure that captures and destroys the organic pollutants to purify the air. The technology, developed and patented by Ahlstrom, consists of a photocatalytic media “combining a layer of active carbon with a nonwoven, which successfully fixes the titanium dioxide, a natural catalyst,” says an Ahlstrom press release. The carbon stays active for four years.
