County Resident Household Hazardous Waste

What makes a household material hazardous?

Household hazardous materials are common products you may use around the home. They must be used, as directed, in a particular, careful manner. Household hazardous waste that is improperly disposed of presents a health threat and may contaminate the water, soil, air or other natural resources. Special handling of these materials is required to minimize environmental risk and protect our health.

A substance is considered hazardous if it ignites easily, reacts or explodes when mixed with other substances, is corrosive or toxic. Check for labels that bear the words or symbols for: caution, warning, danger, poison, or toxic.

Latex Paint

Important Note: Latex paint is not considered household  hazardous waste. Latex paint is commonly used as interior and exterior paint. Read the paint container label to identify the type of paint. Latex paints clean up with water and soap. Oil-based paints clean up with mineral spirits or turpentine. Oil-based paint is hazardous waste and needs to be disposed of as hazardous waste.

How to dispose of latex paint

  • If you have a fuller can of latex paint: 
    • open the can in a safe, well-ventilated space
    • carefully mix in kitty litter, dirt, or sand until it becomes a thick consistency without overflowing
    • allow the paint mixture to dry to a consistency similar to peanut butter
    • place the lid back on the can and dispose of it in your household trash
  • If you have a little bit of latex paint: 
    • open the can and leave it in a safe, well-ventilated space
    • allow the paint to dry solid
    • place the lid back on the can and dispose of it in your household trash

Why are there only a couple of Household Hazardous Waste Collection Days a year?

Because of the diversity of hazardous products and the different disposal techniques needed, it can be very costly to properly dispose of household hazardous waste. The Solid Waste Division covers these costs for you.

What happens to the collected household hazardous waste?

Because this form of waste is highly varied, each category requires special handling and processing. The Solid Waste Division works with a reputable contractor. The collected materials are sorted by their type and required handling. Materials collected by Calvert County are recycled or disposed of in special hazardous waste containment, incineration facilities or reprocessed.
