Keith E Forrester: Disposal of waste ash. Wheelabrator Environmental Systems, Banner Birch McKie & Beckett, August 20, 1991: US05040920 (29 worldwide citation)

Waste ash is controlled and adjusted in its water content to result in a compacted permeability of about 10.sup.-5 cm/s or less. With particle size distribution adjustments, the compacted permeability can be made even lower. The impermeable structure is useful as a cover or cap for existing landfill ...

Keith E Forrester: Immobilization of lead in bottom ash. Wheelabrator Environmental Systems, Banner Birch McKie & Beckett, September 14, 1993: US05245114 (17 worldwide citation)

Bottom ash arising from solid waste combustion has lead (Pb) sufficient quantity to sometimes fail the EPA TCLP test. Addition of water-soluble phosphate, especially phosphoric acid, increases the immobilization of lead (Pb) so as to make such residues in compliance with the toxicity tests over a su ...
