  1. On-line Sorting Technology for CCA-Treated Wood

  2. Funding Received from Sarasota County through the Florida Department of Environmental Protection Innovative Recycling Grants Program

  3. Objective • Construct and Operate an On-Line System for Sorting Treated From Untreated Wood

  4. Background • Research conducted found CCA-treated wood in C&D waste piles • 6% in 1996 (12 C&D facilities) • 9 to 30% in 1999 (3 C&D facilities)

  5. Background U.S. Statistics for Southern Pine Production (From SFPA)

  6. Conceptual Design

  7. Conceptual Design (con’d)

  8. Tasks • Task 1: Obtain Permit and Construct Shelter • Task 2: Design and Construct Conveyor • Task 3: Lab Test and Develop Detector (Laser, LIBS vs X-ray, XRF) • Task 4: Install and Field Test Conveyor and Detector • Task 5: Operate Sorting System and Document Performance

  9. Overall Timeline

  10. Task 1:Obtain Permit and Construct Shelter

  11. Outline • Specifications and location of shelter • Construction process • Shelter construction contractors • Project management • Project schedule

  12. Shelter Description • Metal fabricated building • 30 by 40 feet, 15 foot eave height • Portal frame with open sides, 1:12 sloped roof • Engineered concrete slab

  13. Approximate Size and Roof Line

  14. Portal Frame

  15. Open Sides and Height

  16. Site Layout Machine Shop Proposed Parking Bin Wood Out Shelter C&D Materials Processing Area Wood In Office Trailer Parking Entrance C&D Material Storage Bins

  17. Shelter Location

  18. Construction Process • Metal fabricator - shelter design • County engineer - concrete design • Slab • Anchor bolts • Electric - separate subcontractor

  19. Anchor Bolt Detail

  20. Available Electric

  21. Shelter Contractor Quotes • Uni-Built, Tampa, FL • Dura-Steel, Vernon, FL • Trident, Sarasota, FL • Ranged $9,000 - $17,000

  22. Project Management • Review plans and permit documents • Coordinate inspection schedule of foundations, structural steel and electrical system • Review work in-place prior to scheduled inspection by Building Department • Prepare written summary of field inspections

  24. Task 2:Design and Construct Conveyor

  25. Conveyor (Task 2) • Preliminary Quotes • American Conveyor, Miami, FL ** • Powerscreen, Lakeland, FL

  26. Conveyor (Task 2) Most Recent Design

  27. Conveyor (Task 2)

  28. Task 3:Lab Test and Develop Detector

  29. LIBS vs XRF • Funds will be used for LIBS • Research with XRF will continue if equipment “borrowing” arrangement can be made

  30. Laser-induced Breakdown Spectroscopy (LIBS)

  31. LIBS Spectrum of CCA-treated Wood

  32. LIBS-based Sorting

  33. Sample Configuration of LIBS Probe

  34. Field-deployable Laser: Big Sky Laser

  35. Compact Spectrometer: Ocean Optics

  36. On-line Sorting Technologies

  37. XRF • ASOMA ----> Now Spectro • Contact Harold Soisson • Model 400

  38. XRF • Co XRF ----> Distributors of EDAX • Contact Steve Cox • Model, CT-2000 Note: As detection limit 5 mg/kg
