Waste disposal facility and process therefor

Process for non-polluting disposal of solid wastes collected at a first location, which comprises:

• conveying said wastes along a predetermined path through a plurality of stations;
• reducing the size of said wastes to a predetermined maximum in one station;
• stoichiometrically firing said sized wastes at a temperature below about 2200.degree.F;
• firing said materials a second later time in an oxygen-rich atmosphere;
• and
• directing the gaseous components obtained from said second firing to selected stations along the path of movement of said wastes prior to firing to dehydrate said wastes.

Process for converting solid wastes and waste liquid hydrocarbons to a non-polluting form, which comprises:

• adding a quantity of presized wood to the solid wastes;
• passing said solid wastes and wood through a sizing mill to reduce the same to a predetermined maximum;
• temporarily storing said sized solid wastes and wood;
• dehydrating said stored wastes and wood;
• placing said dehydrated wastes and wood in a rotating kiln;
• storing the waste liquid hydrocarbons in ventilated tanks;
• firing said wastes and wood in said kiln with said waste hydrocarbons and ventilation air from said tanks in an oxygen-starved atmosphere;
• completing combustion of said wastes and wood in an oxygen-rich atmosphere;
• and
• recirculating part of the gaseous materials obtained from the completed combustion into the oxygen-starved atmosphere of said kiln.

Process for converting solid wastes and waste liquid hydrocarbons to a non-polluting form, which comprises:

• storing the waste liquid hydrocarbons in ventilated tanks;
• mixing the waste liquid hydrocarbons with the solid wastes;
• stoichiometrically firing said mixture with ventilation gases from said tanks added thereto;
• and
• subsequently firing said mixture in an oxygen-rich atmosphere.
