Your go-to guide for waste & recycling in the Twin Cities.
Treated wood contains toxic chemicals such as arsenic, a known carcinogen. Never burn treated wood and don't throw it in with the rest of your trash.
Treated lumber including railroad ties and wood furniture is saturated with chemical preservatives that inhibit fungal decay and extend the life of the wood, but some of the chemicals used are toxic. Select, use and dispose of treated wood carefully to protect the health of your family and the environment.
The only safe disposal option for treated wood in the Twin Cities area is to take it to a lined landfill or another facility that accepts treated wood.
Check with your hauler to see if treated wood is accepted for landfill disposal and if there are any fees or preparation requirements.
County household hazardous waste collection sites don’t accept treated wood of any kind.
Consider treated wood alternatives for your next outdoor construction project. Ask your lumberyard or home repair retailer for non-toxic treated wood options.
