Household Hazardous Waste
This item should never be put in a curbside bin. For more information visit our household hazardous waste page.
Pressure treated, preserved wood, or treated wood waste (including the sawdust), referred to as TWW, has preserving chemicals like arsenic. When outdoor structures built with preservative treated wood – such as decks, gazebos, fences and retaining walls – are demolished and discarded, the wood is considered TWW.
TWWDisposal.org has fact sheets and outreach materials on the appropriate handing, disposal (lanfills that accept TWW), and other management of treated wood waste for facilities that may receive or handle treated wood waste. Spanish translation is now enabled on the website.
Painted, engineered, stained, laquered, plywood/composite, and wood painted with "copper green" may go in the garbage.
