The use of the MSAP® Method greatly reduces odor potential, deters vectors and results in a superior compost product with higher levels of beneficial microbes. The Catalyst can also be utilized to enhance material breakdown in Aerated Static Pile (ASP), Covered, and In-Vessel systems. In addition, the Catalyst can be adapted to specifically target and breakdown hydrocarbons and a vast array of man-made pollutants. These contaminants are digested, metabolized, and transformed into inert byproducts, such as carbon dioxide and water.
