Rules & Restrictions
Saturdays ONLY (April through November) from 8am to 4pm at the Alpha Ridge Landfill located at 2350 Marriottsville Road, Marriottsville, Maryland 21104. There are typically three special Saturday collections during the winter off-season.
Residents using the HHW program are required to show their drivers licenses as proof of residence in Howard County.
- DON'T mix different or unknown materials together in the same container.
- Bring materials in their original container or in a secure, clearly labeled, leak-proof container.
- Make sure lids are tight.
- If the container leaks, pack contents and container in a larger leak-proof package and use an absorbent material (such as cat litter) to soak up leaks.
- Group similar materials to make unloading easier.
When arriving at the Residents' Convenience Area, you will be directed to the HHW drop off area and asked to move your items to one of the analyzing tables.
On-site chemists will examine the materials. They may ask for your help in identifying any unlabeled materials that you have brought. Based on their analysis, they will determine the proper packaging for transport and disposal of the hazardous materials.
Additional Resources
Buy Responsibly
- Use white vinegar, salt and water for surface cleaning and baking soda as a toilet cleaner. Detox your home with these easy alternatives.
- Only buy what you need. If you have some left over, share it with friends, neighbors or community groups. Remember that the large economy size ends up costing more when you don't use it all and must dispose leftovers.
- Purchase non-toxic household cleaning products, or safer alternatives, whenever possible. Not all brands contain hazardous materials.
- Use latex paint instead of oil-based paint.
Use Responsibly
- Always read and follow all directions and precautions on labels.
- Never mix products unless directed. Some products are chemically incompatible and may react to cause fumes, fires, or explosives.
- Avoid contact with skin and eyes. Wear protective eyeglasses, gloves and clothing when handling hazardous materials.
- Use products for their intended purpose.
Store Properly
- Keep hazardous materials OUT OF CHILDREN'S AND PET'S REACH, in a dry, secure place.
- Separate flammable, corrosive and poisonous products.
- Keep hazardous products away from food and sources of heat or sparks.
- Store materials in their original containers with the labels intact.
