Waste disposal methods

A method of removing waste material from an industrial site to thereby enhance payload efficiency, as compared to other methods of removing waste material, the method comprising:

• introducing a waste material into an enhanced-payload mobile vessel having an enclosed top portion when positioned at the industrial site, the enhanced-payload mobile vessel connected to a tractor or tractor-trailer, the waste material being comprised of composites of industrial site waste products selected from one or more of a sludge waste material, a solids-laden wastewater material, and a dry waste material so as to include both liquids-phase content and solids-phase content;
• transporting the waste material when positioned in the enhanced-payload mobile vessel along roadways to an off-site waste management facility;
• lifting a front end portion of the enhanced-payload mobile vessel by one or more lifting mechanisms so as to position the waste material to be dumped from a rear end portion of the enhanced-payload mobile vessel at the off-site waste management facility thereby to dispose of the waste material;
• and
• before the transporting at least portions of the liquids-phase content by gravity through one or more discharge ports positioned at the rear end portion of the enhanced-payload mobile vessel when the liquids-phase content layers above settled out solids-phase content to thereby retain the settled out solids-phase content in the enhanced-payload mobile vessel separately from the drained liquids-phase content such that a concentrated solids-phase sludge content remains at a bottom of the enhanced-payload mobile vessel.
