Year 2 ash leaching studies
Year 2: Ash Leaching Studies Beginning of Project

  • Leaching Studies, ash

    • Hazardous when CCA-treated wood represents 5% of wood burned

    • Solvents can extract metals from ash, citric acid very promising (40 to 100% As removed)


Year 2 sorting
Year 2: Sorting Beginning of Project

Untreated

Treated

  • Sorting Studies, Laboratory

    • Chemical stains, low capital costlabor intensive

    • X-ray methods, high capital costsuitable for on-line system
