Household Hazardous Waste Collections
Got a mercury-containing fever thermometer? Trade it in! Bring your mercury thermometer to a Household Hazardous Waste collection and receive a free digital fever thermometer. One per household while supplies last.
Some of your household products may be considered hazardous materials. Improper disposal of these hazardous materials may harm the environment and/or human health. We have a staffed Household Hazardous Waste receiving area at the Shady Grove Transfer Station and Processing Facility, free of charge to residents.
If your business generates hazardous waste, Ecowise, our program for small quantity generators, may meet your disposal needs.
This Household Hazardous Waste program is open to Montgomery County residents with home-generated hazardous waste. All patrons must present valid identification in the form of:
- Driver's License and vehicle registration
When a business cleans up a residence and takes possession of Household Hazardous Waste in the process, that waste becomes its hazardous waste and it must pay to dispose of this material through the Ecowise program, provided it meets the program's quantity requirements.
Shady Grove Solid Waste Transfer Station
The Household Hazardous Waste receiving area at the Transfer Station is located in the recycling drop-off section of the Public Unloading Area. Please use the Car Entrance to the facility.

Preparing Your Materials for Transport to the Collection Sites

- Check all containers to make sure lids are tight.
- If container leaks, pack contents and container in a larger package and use an absorbent material, such as cat litter, to soak up leaks.
- Group similar materials in the same area of your car to make unloading easier (ex.: group all oil-based paints together)
- Handle car batteries with damaged cases or missing filler caps with extreme care.
- Boxes with dividers make good packaging.
- DON'T mix or pour different or unknown materials together in the same container!
What to expect at the Collection Site

- On-site chemists will examine the materials and determine the proper packaging for transport and disposal of the hazardous materials.
