Treated Wood Waste (TWW) Is Accepted At All Salinas Valley Recycles Locations
TWW is considered a Hazardous Material
TWW contains hazardous chemicals that pose a risk to human health and the environment. Arsenic, chromium, copper, creosote, and pentachlorophenol are among the chemicals used to preserve wood and are known to be toxic or carcinogenic. Harmful exposure to these chemicals may result from touching, inhaling or ingesting TWW particulate (e.g., leaching liquids, sawdust and smoke).

Treated wood is wood that has gone through a treatment process with chemical preservatives to protect it against pests and environmental conditions. Typically, treated wood is used in exterior applications where ground or water contact is likely.
Treated wood can often be visually distinguished by its appearance. There are several signs to look out for when determining if a piece of wood has been treated or not. What are some things to look for when determining if wood is treated or not?
- Treated wood end tag
- Wood manufacturer stamp codes
- Indentations on the surface of the wood (as seen in the photo above)
- When cut, staining is visible around the perimeter only
- Discoloration (e.g. green or dark brown appearance)
- Odor
Example of pressure treated wood showing indentations from treatment.

TWW is charged at the garbage rate because it is buried in the landfill. Regular lumber or clean wood is brought in at a reduced rate because it is recycled. Please separate treated from non-treated wood wastes to receive the reduced rate.
