Holmes, W H

A waste to fuel processing system is claimed wherein solid municipal waste is converted to usable industrial fuel. The waste is deposited in a relatively large ''pick'' or receiving pit having mechanical means for removing very bulky, outsized material. The remaining waste is delivered by conveyor to a first rotating trommel having holes that are at least one foot in diameter. Combustible material over a foot in diameter which is rejected by the first trommel is reduced by coarse shredding and remixed with the other combustibles at the packaging apparatus. Material that passes through the holes of the trommel is delivered by conveyor to a second rotating trommel having holes that do not exceed 2.5 inches in diameter. In the second trommel, frangible material along with small stones and dirt drops through the holes and the remaining waste is delivered by conveyor to packaging apparatus, such as a baler or compactor, for conditioning it for use as fuel.
