Biological Waste Digestant

MBI-500™ is an economical, proprietary combination of biologicals used to accelerate biodegradation of wastes found in grease traps, food processing plants and lagoons, septic tanks, and agricultural waste collection systems.  It degrades unsaturated fat, oil, milk, starch, protein, and other biologically- derived waste. The metabolic processes of MBI-500™ microbes produce biochemicals and enzymes that break down targeted wastes. MBI-500™ comes as a ready-to-use liquid formulation.

MBI-500™ includes multiple strains of facultative microbes which remain active in aerobic or anaerobic conditions.
