Presentation Transcript

  1. Augmented Sorting of Recovered Wood Waste Using Stain and X-Ray TechnologiesRecently Awarded by the FDEP Innovative Recycling Grants Program to the Town of Medley

  2. Objectives • Evaluate two innovative technologies for identifying and removing CCA-treated wood within recovered wood waste. • PAN Indicator Stain • X-ray Technology (hand-held units)

  3. Tasks Phase I • Sort 10 tons (minimum) of dimensional C&D waste wood using visual methods, PAN stain and XRF unit • Document speed and costs. Phase II • Picking Line Sorts • No augmentation • With stain • With XRF • Documentation

  4. Host Facility Project Collaborators

  5. Why Are New Methods Needed for Sorting?

  6. Time consuming but inexpensive For a few samples Suited for on-line applications Sorting Technologies (Previous Work) Chemical Stains Arsenic Test Kit Laser (LIBS) X-ray (XRF)

  7. Chemical Stains • Low Capital Cost, Labor Intensive • Chemical stains • Chrome Azurol • PAN Indicator** • Rubeanic Acid Untreated Treated Stains Are Not Arsenic Specific

  8. On-Line Technologies (Previous Work in Sarasota County) Laser Induced Breakdown Spectroscopy (LIBS) X-Ray Flourescence Spectroscopy (XRF)

  9. DETECTORS laser x-ray

  10. X-Ray Fluorescence Technology

  11. Theory of X-Ray Fluorescence Incident X-ray from the analyzer strikes an electron occupying the lowest shell Electron is ejected An upper-shell electron drops down to fill the vacancy X-ray characteristic to this elements’ energy is emitted Nucleus Ejected e- Transitioned e- Incident X-Ray Emitted X-Ray

  12. XRF Field Photos
