An improved flowable fill material and method for producing same that
provides a medium for disposal of waste wood or other reclaimed debris,
including wood treated with anti-microbial and/or anti-fungal materials
including those containing copper, chromium and arsenic bearing
compounds. The flowable fill material, comprised entirely of recovered
and/or recycled materials, provides a medium for the safe disposal of
chipped wood or other recovered waste by effectively encapsulating wood
chips and substantially retarding further decomposition. Encapsulation of
treated wood substantially reduces leaching of arsenic and/or other toxic
substances contained therein. The systematic mixing of water, Class C fly
ash, and wood chips in specific proportions carries out the present
invention.
