Local Household Hazardous Materials (HHW) Collection Programs 

The Annotated Code of Maryland, Environment Article § 9-1801, defines Household Hazardous Waste (HHW) is any waste material, including garbage or trash, derived from a household that would be listed as hazardous waste under the Resource Conservation and Recovery Act but for the fact that the waste is derived from a household.  Household hazardous waste may include:  agricultural chemicals, cleaning agents and solvents, paint, pesticides, and preservatives.

Maryland does not regulate HHW as hazardous waste and Federal law allows for the disposal of HHW in household trash.  However, due to the potential of HHW to cause physical injury, contaminate septic tanks or wastewater treatment systems, and present hazards to children and pets, MDE recommends the proper recycling/disposal of HHW materials at local HHW collection programs.

Many Maryland counties have programs in place to collect HHW such as mercury, paint, paint thinner, pesticides, herbicides, batteries, and to a lesser extent medications.  The chart below shows the counties, names of contacts and current status of these programs. Some counties have HHW day only once a year so contact your county to find out when the next collection day is and ask what materials they will accept.
