Household Hazardous Waste
Each Household Hazardous Waste (HHW) Collection site is open one day per month from 12 p.m. to 7 p.m. and the service is free. Waste must be dropped off only when a Household Hazardous Waste Collection vehicle is present.
Collection Site Rules
You can not leave your car and walk up to the site. You MUST remain in your car at all times for safety reasons. Mixing cars and with pedestrians potentially walking up to the collection site from any and all directions is never a good idea and when you add handling and sorting hazardous waste, it increases the safety risk for everyone.
Expect to wait if you visit before or just after a collection site opens; it is common for a line to form in the 30 minutes before a site opens. Expect to wait if you visit a site after 4 pm when many try and stop on their way home from work.
Expect extended wait times after holidays.
Please be patient if there is a line. Our staff must look at each container to ensure it is placed with compatible materials.
Only small (no larger than trunk-sized) loads are accepted at the collection sites. There are limits on certain types of waste; please see accepted materials for those limits. Larger loads or major clean-out loads must be taken to the Hazardous Waste Facility at the Ada County Landfill. The facility is open Fridays and Saturdays from 8 am to 6 pm.
HHW Collection is closed on the following holidays:
- New Year's Day
- Memorial Day
- Independence Day
- Labor Day
- Thanksgiving Day
- Christmas (Please note: if a collection site is open on Christmas Eve, the site will close early at 4:00 p.m.)
Do not leave items at a site when collection vehicle is not present as it creates hazardous conditions and violates Boise City Code.
What Is Household Hazardous Waste?
Household Hazardous Waste (HHW) comes from products used for cleaning, home improvements, automobile maintenance, and lawn and garden care contain ingredients that can harm human health and the environment. Properly disposing of these hazardous products will keep our community safe and clean.
Items such as solvents, paint/stain/varnish, yard/garden products (including pesticides and herbicides), batteries, automotive products (including gasoline and oil), compact fluorescent light tubes, TVs, and computer monitors are considered hazardous waste.
If something is hazardous, the label will contain one of these signal words:
- Environmental Hazard
If the label contains one or more of these words, it is hazardous waste and is accepted at household hazardous waste collection sites. Do not throw hazardous waste in with your trash, recycling or compost.
Proper Lithium Battery Disposal
Did you know that improper Lithium Ion battery disposal can be a safety hazard to collection truck drivers? Lithium Ion batteries can catch fire if disposed of incorrectly.
In 2020, Boise Fire responded to a trash trailer fire at Republic Services that was caused by the improper disposal of a Lithium Ion battery.
View our disposal tips video to learn how to properly dispose of batteries and keep our collection drivers and equipment safe.
Below is a list of common battery types and how to dispose of them properly
- Alkaline - (AA, AAA, C, D)

Commercial and Businesses
Who Can Participate?
Businesses or organizations located within Ada County that are considered a Very Small Quantity Generator (VSQG) under the Resource Conservation and Recovery Act (RCRA) and/or generate wastes regulated under the Universal Waste Rule (e.g. fluorescent and compact fluorescent light bulbs).
Under RCRA, VSQG must meet three conditions:
- Produce less than 220 pounds of hazardous waste each month
- Produce less than 2.2 pounds of acutely hazardous waste [as defined in 40CFR261.31, 261.32, 261.33(e)] each month
- Store no more than 2,200 pounds of hazardous waste on site
Calculating How Much Waste Your Business Produces
To determine generator status, you must do the following:
- Look at all waste streams generated at your facility
- Determine which waste streams are hazardous
- Estimate the quantity of hazardous waste generated and stored each month (Use the standard of one gallon equals eight pounds to estimate total pounds.)
If your business includes more than one location, calculate quantities from each location separately. If the total amount of wastes generated at your facility is less than 220 pounds per month AND you also meet the other criteria, your business is eligible to register for the program.
Waste to Register

Electronics accepted include televisions, computers (monitor, keyboard, mouse, and CPUs), printers, fax machines, and scanners.

However, used amalgam or teeth containing amalgam fillings is considered biomedical waste and is not accepted. Cell phones are also accepted.

Cost depends on the type of waste that is generated and is charged by the pound. Businesses are charged disposal costs only. There is no fee for electronics.
