This invention was developed by combining a series of technologies to work in concert to convert wastes to useful commodities. A vast improvement over just moving waste to different locations. Combustible materials such as municipal garbage, tires, plastic, paper, etc. are converted to gases in a high temperature, oxygen starved oven, that has proven capable of burning without emitting smoke or unacceptable emissions. The gases are burned in high temperature after-burners creating energy that is used to generate electricity and heat. In other words co-generation using tires and garbage for fuel. The Thermophilic Digester draws heat from the burner to create an ideal environment to enhance the production of enzymes. Electricity is supplied from the co-generation unit to operate the pumps, choppers and compressor. Air is injected in perforated pipes that are situated in the bottom of round horizontal tanks to provide oxygen for the bacterial function and convectively circulates the sludge without the need for mechanical paddles. This system reduces maintenance and operating costs. The odours and gases generated by the digestors in the treatment process are drawn off and channelled into the oven and afterburners. The undigestible solids that remain are used as fertilizer. In the event they contain heavy metals as occurs in some areas these are recovered by dissolving said metals with sulphur dioxide in a closed circuit system and separating same by precipitation and filtration.
