Accepted Materials


Household Hazardous Waste (HHW)

The following list of materials can be brought to a Boise City mobile collection site. However, space is limited and we cannot accept large quantities of items. 

We can take up to 25 items or small loads that will easily fit into the cargo area of a small SUV or trunk of a car. Larger quantities or pickup truck-sized loads of household hazardous waste must be taken to the Household Hazardous Waste (HHW) Facility at the Ada County  Landfill. If you have questions about specific materials, call the Boise Public Works Department at (208) 384-3901.

Note: Do NOT leave items at a site when a collection vehicle is not present. Leaving toxic chemicals unattended creates hazardous conditions and is a violation of Boise City Code 8-10-4.01 and 8-10-5.08. The sites are CLOSED on New Year's Day, Memorial Day, July 4th, Labor Day, Thanksgiving, and Christmas.
