Never Burn Treated Wood

Chemicals such as creosote are used when treating wood, which creates toxic ash and emissions when burned. These particles lodge in soil and groundwater and take many years to break down, so never burn wood if you think it has been treated.


Take Care With Sawdust

Avoid breathing in sawdust from treated wood, and do not add it to compost or scatter on the ground.

Ways to Reduce


Choose a Different Wood

Redwood and cedar are both naturally pest-resistant. Suppliers are also starting to offer more non-toxic treated wood options.
