Posi-Shell®‘s mineral foundation offers a natural filter uniquely effective at controlling landfill odors. No cover system, including soil or other ADC’s, comes close to the odor suppression performance of Posi-Shell®. Landfill managers around the world rely on Posi-Shell® to keep the peace with neighbors and regulators.

For challenging odors generated by sewage sludge, landfill excavations, or composting operations, our innovative Odor-Shell® product can be used independently or in conjunction with Posi-Shell®. Unlike systems that attempt to address airborne odors, Odor-Shell® is topically applied using three synergistic mechanisms of sealing, filtering, and neutralizing to kill odors before they become a problem.
