Smog-Reducing Granules

The 3M™ Industrial Mineral Products Division recently launched 3M Smog-reducing Granules to help remove smog pollution using roofing shingles. Integrated throughout a shingle’s surface, 3M’s roofing granules are designed with a specialized photocatalytic coating applied to the base mineral. The specialized coating on the granule is activated by the sun’s UV rays, while blending inconspicuously into various shingle color combinations. As sunlight hits the shingles containing the smog-reducing granules, radicals are generated and transform nitrogen oxide gases into water-soluble ions improving air quality. This smart solution for pollution mitigation can help communities contribute toward their NOx emission reduction efforts.

 

 

 

 

 

 

 

 

 

The roofing granules are a first for residential asphalt shingles. The new 3M granules will help roofing manufacturers develop high-quality, aesthetically-pleasing shingles that can turn any roof into an active smog reducing catalyst, essentially becoming smog’s worst enemy. Smog-reducing technology, embedded into mainstream roofing materials, is a great step forward in addressing air quality and climate concerns.
