Waste & Wastewater Treatment
In-Vessel Compost Maturation Tank (VCMT)
Patented In-Vessel Compost Maturation Tank (VCMT) technology that accelerates the composting process from several weeks to just days, producing odor-free, high-quality compost without the need for large outdoor areas. The system uses dual counter-rotating augers, heated pressurized aeration, UV sterilization, and enzyme injection to rapidly convert organic waste into ready-to-use humus. Available in horizontal (cylindrical) and vertical (silo) configurations for municipal, agricultural, and industrial applications. Protected under US Patent Application #20090145188.
