Household Hazardous Waste

Household Hazardous Wastes are chemicals that are used in our daily lives and can be found in most of our homes - in the workshop, under the sink, and in the garage. These chemicals are corrosive, flammable, toxic, or reactive, and can cause damage to the environment and/or public health if they are not handled and disposed of properly. The City of Nashua and surrounding communities work together to provide opportunities for residents to safely dispose of unwanted hazardous waste. Residents of Nashua, as well as Amherst, Brookline, Hollis, Hudson, Litchfield, Merrimack, Milford, Mont Vernon, Pelham and Windham are eligible to participate in any of the events.


Household Hazardous Waste Collections have ended for 2023 and will resume in April for the 2024 season. Thank you to all who participated.

There will be one drop off location outside of Nashua in 2024 - to be determined at a later date.

The cost is $15 per vehicle, for up to 10 gallons or 20 pounds. Please carpool if possible!

How to Safely Handle & Transport Household Hazardous Waste

  • Keep materials in original containers, securely closed. Leaking or broken containers must be placed inside other containers.
  • Pack containers in sturdy boxes lined with a trash bag and if necessary, padded with newspapers.
  • Never mix chemicals together.
  • Never smoke or eat while handling or transporting hazardous materials.
  • Leave children and pets at home when transporting hazardous waste to a collection event.
  • At the collection site, do not leave your vehicle unless instructed to do so.
