Household Hazardous Waste

Hampstead residents have the opportunity to responsible dispose of household hazardous waste (HHW) twice a year.  Each spring and fall we participate in an event that involves surrounding towns.

Upcoming Household Hazardous Waste Collection Days:

Fall 2022: in Kingston NH- October 29, 2022 9 am to noon  12 Main Street, Kingston, NH (DPW- directions on the flyer)

Please note that Hampstead residents must show proof of residency.

See below for items GENERALLY accepted at HHW events.  As a rule of thumb, products that have the following words on the labels are accepted: caution, toxic, combustible, poison, flammable, warning, and danger.  Note that latex paint is NOT a hazardous material since it is water based.
To dispose curbside you must harden it with paint hardener, sand, or kitty litter, and ensure it has time to set or dry up.

ALSO, the Hampstead Town Garage accepts old gas and oil and empty propane tanks the 1st and 3rd Saturday of each month.  The Town Garage is located at 35 Stage Road (Rt. 121)
