Mashpee household hazardous waste: 2026 dates and what comes next

How the Mashpee program works

The town page says hazardous waste collections are free to Mashpee, Bourne, Falmouth, Sandwich and Coast Guard Air Station residents. It asks you to bring proof of residency, and hours are 9 a.m. to 1 p.m. The 2026 list: April 18 at Sandwich High School, June 20 at Falmouth High School, August 22 at Mashpee High School, October 17 at Bourne Landfill. All four have passed.

Barnstable County runs the program and says the 2026 season has ended and the 2027 schedule and updated town brochures will be posted in spring 2027. Questions go to the county line, 1-800-319-2783. Residents who cannot attend can use another Cape town's event for a fee; the town page links the list and participation form.

What to bring and what is turned away

The town lists pesticides, herbicides and fungicides, gasoline and brake fluid, drain cleaners and solvents, oil-based and marine paints and stains, paint thinners and strippers, pool chemicals and two-part adhesives. Latex is the exception that surprises people: latex and acrylic paints and water-based stains are not hazardous. Dry them in kitty litter and put the box in household trash; recycle open dry cans.

Not taken: medical or biohazardous waste, explosives, ammunition, fireworks and flares, and smoke detectors (trash). Things the collection does not want go to the Transfer Station, such as used oil, batteries, fluorescent bulbs, TVs and propane tanks, some for a fee. Needles and syringes go to the DPW at 350 Meetinghouse Road, and unused prescriptions to the Mashpee Police Station drop box in the lobby.

Between collections, and what JUNKRUN does not take

The 2026 August event at Mashpee High School also ran free textile recycling and secure paper shredding (no businesses). Those are not on a schedule now either. Keep chemicals in the original containers, away from the heat of an unheated shed in winter, and off the floor of a cellar that floods.

JUNKRUN does not haul hazardous waste: paint thinner, pesticides, gasoline and pool chemicals. We can take the rest of the garage around them: a quarter trailer $209, a half $319, three-quarters $409, full $519, $159 minimum. Leave the hazardous items out of the pile and set aside for the next county Saturday.
