Original motivation for project

Original Motivation For Project

Ash Disposal Problem, 1995


Fcshwm year 1 1996 1997

FCSHWM Year 1 (1996-1997)


Year 1 c d wood testing

Year 1: C&D Wood Testing

  • Processed Wood at C&D Recycling Facilities

    6% CCA by Weight

Fcshwm year 2 1997 1998

FCSHWM Year 2 (1997-1998)


Year 2 ash leaching studies

Year 2: Ash Leaching Studies

  • 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

Untreated

Treated

  • Sorting Studies, Laboratory

    • Chemical stains, low capital costlabor intensive

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