Treated wood waste
Treated wood usually designates as dangerous waste. Wood is “treated” (i.e. dipped, sprayed, or pressure-treated) with chemicals that protect it from natural decay caused by insects, fungi, and other environmental factors. These chemicals pose risks to human health and the environment.
Businesses that handle treated wood waste — most commonly construction and demolition sites — can often manage these materials under the treated wood exclusion.
If you are a household or individual with treated wood waste, either reuse it as treated wood (original intent), or dispose of it in household trash or a moderate risk waste facility. Never burn, compost, or mulch.
How do businesses manage treated wood waste?
Determine if you can manage your treated wood waste under the treated wood exclusion. If you cannot manage your treated wood waste under the exclusion, then designate the waste and manage it accordingly.
