Household Hazardous Materials (HHM)

What Are Household Hazardous Materials (HHM)?

  • HHM are products found in the home that are flammable, corrosive, poisonous or potentially hazardous.
  • HHM products typically found in the kitchen, bathroom, workshop or garage contain hazardous ingredients that poses human health and environmental risks when managed improperly.
  • Household electronics, such as TVs and computers, often contain hazardous and toxic materials that pose environmental risks if they’re taken to a landfill or incinerated.

What’s Accepted for HHM Drop Off

The HHM Facility accepts most solid, liquid, compressed gas and aerosol products typically used in the home that are flammable, corrosive or poisonous. There’s no charge to residents for a HHM drop-off.

  • Product labels with signal words like “danger,” “warning” or “caution,” followed by a statement of the principle hazard(s) (“combustible,” “caustic,” “toxic”) are indications you have an HHM requiring precautionary measuring during its use and proper waste management disposal.
  • The HHM Facility/Electronics Collection and Recycling Center is open only to residents and County employees for drop-offs. Business and commercial hazardous materials are not accepted.

Look Up Your Item & How To Prepare

Unaccepted Materials

Latex Paint

If the can is less than 25 percent full of latex paint, it may be solidified at home by the resident for disposal via curbside trash collection. For the home disposal process, you should wear old clothing, gloves and eye protection. Work in a well-ventilated area. Add kitty litter to the open latex paint cans. Stir in enough kitty litter to achieve a very thick paste. Place the cans in a trash bag inside your trash cart for collection. If the can is more than 25 percent full of latex paint, arrange for drop-off at the HHM Facility by calling 703-228-5000.

Mercury

Each mercury thermometer contains one gram of mercury, enough to contaminate a 20-acre lake. Devices containing mercury should be dropped off at the HHM Facility.

Motor Oil

Motor oil should be dropped off at the HHM Facility.

  • Use a dirt-free pan that can hold as many quarts as your car’s crankcase, a pan that has not been used for paint, cleaning solvents, antifreeze or other chemicals besides motor oil.
  • Pour your used oil from the drain pan into a container with a leak-proof lid, such as a rinsed-out plastic milk jug. Use a funnel to avoid spills. Don’t mix or blend your oil.
  • If you change your oil filter, drain the old one by punching a hole in the top and inverting it over your drain pan. Dispose of the old filter by putting paper towels over the hole. Then put the old filter and paper towels in the box your new filter came in. Place the box in the trash.
  • To reuse your used oil container, put the lid back on and save it for your next oil change. Store it away from children and pets.

Battery Collection Points

Fire Stations Accepting Rechargeable, Lithium, Silver Oxide and Mercury Batteries

  • Regular household (alkaline and zinc carbon) batteries should be disposed of in your regular trash collection.
  • Rechargeable batteries, as well as lithium, silver oxide, and mercury batteries, should be dropped off in special collection boxes located at most Arlington County fire stations or at the HHM Facility.
  • Car batteries can be collected with curbside recycling. You need to submit a request by calling 703-228-5000. Car batteries can also be dropped off at the HHM Facility.

Compact Fluorescent Light Bulbs

CFLs contain mercury and shouldn’t be thrown in the trash.

CFL Drop-Off Sites

Fluorescent Tubes

Fluorescent tubes are one of the most popular and widely used lighting options available, but contain mercury and thus must be correctly disposed.

Do not throw fluorescent tubes in the trash. Please take these bulbs to the HHM Facility at Water Pollution Control Plant for proper disposal.

E-CARE

Chemicals

An E-CARE drop-off event is held on a Saturday in spring and fall, offering Arlington residents the chance to safely and quickly dispose of HHM, metal, batteries, lighting and other accumulated items without tossing them in the trash. Bicycle donations are also accepted at E-CARE. The HHM facility is closed on Saturdays when E-CARE takes place. Find out more about the E-CARE.
