Household Hazardous Wastes

Drop-Off Events to Collect Residential Hazardous Wastes


To assist residents with proper disposal of hazardous wastes, the Frederick County Division of Solid Waste and Recycling hosts free drop-off events each year for household hazardous material disposal (not for commercial waste).

The date for the spring 2022 event has not yet been set by the hazardous materials contractor. 

Get automatic notifications and reminders for these events! Click the “Recycling Schedule” link on our home page to sign up for free email, phone, text, or mobile notifications of our events! These events are also advertised in the Frederick News Post several weeks in advance, as well as posted to our Facebook page.

See event flyer here for complete details on what is - and is not- accepted as household hazardous waste.

These events do not take place at the landfill. Recent events have occurred at NYMEO Field/Keys Baseball stadium parking lot, 21 Stadium Drive, Frederick 21703. (Enter from New Design Road, not by turning off of South Market Street.) Thank you!

Compact Fluorescent Light Bulbs (CFL) 

According to the U.S. government Energy Star program, a compact fluorescent light bulb (CFL) uses 75% less energy and lasts about 10 times longer than an incandescent bulb! Part of what makes these bulbs work so efficiently is the small amounts of mercury they contain. This also means that they need to be handled carefully, and like any other potentially hazardous substance in your home, they need to be disposed of outside the regular waste system.

Note: Please don't toss CFL bulbs in your regular household trash!

Proper Disposal

  • Any fluorescent bulbs may be brought to the County's Household Hazardous Waste Drop Off events.
  • Some businesses, including The Home Depot and Lowes, accept CFL bulbs for recycling year round (see their websites for more information).

More detailed information on compact fluorescent light bulbs, including disposal options and what to do if a bulb breaks in your home, can be found at the EPA website.
