Sampling of C&D Wastewood
 

Wood is one of the largest components of the C&D waste.  At C&D recycling facilities,
large pieces of  wood are typically separated from the mixed C&D waste in the tipping area. Wood in the remaining waste may still be removed by a variety of manual and mechanical means.
 

Separated wood is removed from tipping area.  Note pile of remaining mixed C&D waste in background (includes some wood).

Wood waste being processed at a C&D recycling facility
 

Wood is processed either at the C&D facility, or at another processing facility.  Tub grinders are commonly used.
 

In some cases, CCA wood can be identified in mixed wood stream (example, utility poles).
Identification is more difficult for dimensional lumber or weathered wood.
 

CCA-treated utility poles separated at C&D recycling facility.
 

Mixed wood recovered C&D waste.  Some pieces of CCA wood are evident.
 

Once the wood is chipped, separation of treated and non-treated wood becomes almost impossible.
 

In an effort to determine the amount of CCA wood typically present in 
Florida's C&D wood stream, samples of chipped wood were collected
from random locations of chipped wood piles at C&D recycling facilities.
