NOVELTY - The system has a greenhouse (20) that is provided for pre-drying bio-solids to reduce volume and weight. A conveyer belt is operably connected to the greenhouse for conveying the bio-solids from the greenhouse to a pasteurization system having a burner-fan to introduce hot air to the bio-solids. The pasteurization system is provided with a pasteurization belt to hold the bio-solids at 70 degrees C for thirty minutes. A bio-filter system (40) is operably connected with the greenhouse and the pasteurization system for reducing odors. A bagging area is provided to collect a final product.    USE - System for converting bio-solids such as solid, semi-solid or liquid residue to Class A fertilizer used in rural farm area.    ADVANTAGE - The exchange rate meets the suggested national fire protection association standards to reduce the possibility of accumulation of combustible vapors for continuously vented areas having exposed bio-solids. The air that has absorbed moisture from the drying process is exhausted with the design of the greenhouses, so that the ability of the media to maintain the desired moisture content is improved.    DETAILED DESCRIPTION - A heat up belt is provided to accept the bio-solids from the greenhouse and the fan for raising the bio-solids temperature from ambient to 70 degrees C. The greenhouse has an air handler (100) for removing moist air and introducing fresh air. The exhaust fans (75) are provided for removing moist air and introducing fresh air. The bio-filter system is operably connected with the exhaust fans to remove odors from the air. The bio-filter system is operably connected with the air handlers to remove odors from the air. The heat up belt and the pasteurization belt are provided with an air permeable material. The burner-fan is fueled with natural gas, liquid petroleum, digester gas, landfill gas, methane or electricity. The greenhouse is provided with two pods having several chambers. A heat up belt and pasteurization belt are provided with a variable speed control. The bio-filter system has a wood-chip/organic mulch blend and a moisture content control. An INDEPENDENT CLAIM is included for a method for treating bio-solids involves introducing bio-solids to a greenhouse. The water content of the bio-solid is reduced by 30% to 40%. The bio-solids are converted to the pasteurization system. The air in the greenhouse is replenished with dryer air. The water content of the bio-solids is decreased to less than about 25% to achieve vector attraction reduction requirements. The hot air or gas is actively exhausted with an exhaust blower. The air is exchanged twelve times per hour. The temperature of the bio-solids is increased to about 70 degrees C by allowing hot air to permeate the bio-solids and traverses the length of the heat up belt lasts about ten minutes.
