12. The Contribution of Wood to C&D Debris
13. Survey of Disposal Facilities in Florida Provide data/information on the occurrence of CCA-treated wood in the waste stream.
14. Survey of Disposal Facilities 23 facilities were visited across the state between February 26 – May 4
Class III landfills
C&D landfills
Materials Recycling Facilities (MRFs)
Class I landfill (one facility)
Staff observed that there is very little difference in the type of waste accepted at Class III landfills and C&D landfills.
17. Survey of Disposal Facilities
18. Preliminary Data!!
Total # of loads observed = 342
Est. total volume of all loads = 6501 yd3
# of loads containing wood = 319 or 93% (319/342)
Est. total volume of wood = 1566 yd3 or 24% (1566/6501)
# of loads contained treated wood = 141 or 41% (141/342)
Est. total volume of treated wood = 261 yd3 or 4% (261/6501)
Survey of Disposal Facilities
20. Due to safety issues, the source of the loads (residential/ commercial, construction/ demolition/ renovation, etc.) could not be determined for all loads. Survey of Disposal Facilities
21. Dedicated Loads (Deck/Dock)
22. Dedicated Loads
23. So, the PRELIMINARY data indicates that only 1.5% of the 342 loads were “dedicated loads”.
24. Dedicated load from a dock builder
25. The identification and removal of CCA-treated wood is VERY difficult in some instances.
27. Identification of treated wood is difficult when the wood is painted.
28. End tags help identify CCA-treated wood
30. Is it CCA, ACQ or Copper Azole?
31. Color differences between untreated and treated wood (NOT WEATHERED)
32. Mixed wood debris
33. Weathering and paint make identification difficult
34. Treated wood may be hidden in landscaping and yard waste
35. Survey of Disposal Facilities Of the 141 loads that contained treated wood:
63% were identified by the greenish hue
37% were from a structure that is typically treated (fence, deck, dock, etc.)
10% were identified through consultation with landfill staff, hauler, or other expert
5% were identified by end tags
*note: some loads were identified using more than one method

42. How waste enters MRFs
43. Waste Sorting at MRFs
45. A concrete tipping floor such as this makes picking and sorting easier
46. Some landfills have more area for walking around the waste to sort out recyclables
47. Most landfills have little room for sorting waste after tipping
48. Phone Survey
49. Contractors – 14
Decks – 6
Demolition – 5
Docks – 31
Fencing – 140
Marine – 34
Woodworks - 2
Businesses that participated
50. Typical Uses Decks, Boardwalks
51. Typical Uses Fences
52. Typical Uses Docks
53. Typical Uses Utility Poles
56. Phone Survey Results General contractors reported CCA-treated wood was in SOME of their loads
Deck Builders reported that nearly ALL the decks were CCA-treated
Demolition Contractors reported that VERY FEW of their loads contained CCA-treated wood
Dock Builders reported that MOST docks were CCA-treated
57. Fence Builders
21% reported less than half of their discarded wood waste was CCA-treated
2% reported that half of their discarded wood was CCA-treated
38% reported that most of their discarded wood waste was CCA-treated
39% were unsure how much of their discarded wood was CCA-treated
58. Marine Contractors
14% said a small amount of their wood waste was CCA-treated
12% said most of their wood waste was CCA-treated
56% said all of their wood waste was CCA-treated
18% were unsure how much of their discarded wood was CCA-treated
60. Waste wood disposed in a roll-off
