Household Hazardous and Electronic Waste Disposal

The City and County of Broomfield typically hosts two one-day Household Hazardous and Electronic Waste drop-off events each year: one in the spring and one in the fall. Both events require an appointment.

Drop-off events will take place at the Broomfield Municipal Shops located at 3951 W 144th Ave. in Broomfield, CO 80023.

Participate in the 2026 Spring Event, or the Boulder County Hazardous Waste Facility accepts household waste free of charge year-round. They are located at 1901 63rd St in Boulder and can be reached at 720.564.2251. Appointments are not required to drop off materials. 

The 2026 Spring Event will be held on Saturday, May 2, from 8 a.m. - 12 p.m. 

We will begin accepting appointments on April 6, 2026.

Acceptable items:

Electronic waste is also accepted during this event. Please note that there is a 3-item limit on electronics. For example, 2 TVs and 1 computer would be the max for one household. Corded appliances, such as microwaves and vacuum cleaners, can usually go in the regular trash or to a scrap metal facility. Check with your local trash hauler for acceptable items. 

If you have additional questions or need more information, please call 303-438-6329 Monday - Friday, 8 a.m.-5 p.m.  or email sguyot@broomfield.org.

Tips to help reduce the amount of HHW generated:

READ LABELS: Read and follow directions carefully!

THINK SMALL: Use the correct amount of product recommended. For example, with pesticide use, twice as much is not twice as effective and may be twice as toxic!

NON-TOXIC ALTERNATIVES: Purchase the least toxic product available. Danger, Caution, Warning, Harmful, Poison, Toxic, Corrosive, Volatile, Flammable, Inflammable, Combustible or Explosive—these words should alert you to the hazardous nature of the product. Choose water-based products over solvent-based ones. Avoid aerosols if you can. Avoid products containing chlorinated compounds, petroleum distillates, phenols and formaldehyde.

STORE PROPERLY: Always store products in their original containers with labels. Store unsafe products away from small children and pets.

DON’T MIX: Some household products, when mixed, can form dangerous fumes or may become explosive. Never mix anything with products containing chlorine or ammonia.

PLAN AHEAD: Buy only what you need to avoid or minimize waste. Don’t be tempted to buy a gallon if you only need a cup. Think about how you are going to dispose of any materials you have left over. Give leftover products to a responsible neighbor or friend who can use it up rather than throwing it out.
