DST™ Dust-Suppression Technology

Enhance worker safety by significantly reducing silica dust

DST™ Dust-Suppression Technology enhances worker safety by significantly reducing potential exposure to silica dust. This technology, which began as a collaboration with a customer who asked us to create a treated sand aligned with stricter OSHA regulations, is gaining significant momentum. Roofing, glass, construction materials and building products companies are choosing this breakthrough technology as part of their engineering control plan to significantly reduce potential exposure to silica dust. 

These companies have confirmed the dust-suppression integrity with multiple in-plant trials. Significantly, these production trials match Covia's internal R&D air quality simulations, which we simplified for you in the video.
