Household hazardous waste in Falmouth: the Barnstable County collections

School parking lot on a Saturday morning set up with cones, tarps and plastic bins for household hazardous waste collection

How the Cape's program works

Collections on Cape Cod are a collaboration between Barnstable County and individual municipalities. Falmouth belongs to a regional group with Bourne, Mashpee, Sandwich and Joint Base Cape. In 2026 the stops were April 18 in Sandwich, June 20 at Falmouth High School, 874 Gifford Street, August 22 in Mashpee and October 17 at the Bourne Landfill, all Saturdays, 9 a.m. to 1 p.m.

Town residents participate for free and need proof of residency; non-residents must register in advance. The county number is 1-800-319-2783.

What to bring and what to leave home

Accepted by the county: oil-based paints, stains and varnishes, paint thinners, lawn and garden chemicals, household cleaners, pool chemicals, gasoline and automotive fluids, and mercury items. Latex paint is not hazardous waste: the town says to dry it out or mix it with cat litter and put it in the trash.

Not accepted at the collection: unknown or unlabeled materials, medical waste and sharps, plus batteries, propane tanks, smoke detectors and fluorescent bulbs. Batteries and bulbs have their own sheds, free and sticker-free, on the lower level of the Waste Management Facility. Small businesses can call Cape Cod Cooperative Extension at (508) 375-6699.

Between collection days

Falmouth's guide says to hold oil-based paint, pesticides and household chemicals for the collection day. Keep them in their original containers. A seasonal home closing in October has a problem: the last 2026 collection, in Bourne, was October 17, and the next stop is not scheduled yet.

The next scheduled event listed on the town's recycling page is a Fix-It Clinic on November 14, 2026 at St. Barnabas's Church (sign-up is by form). It does not take hazardous waste. JUNKRUN does not take hazardous materials either; paint, solvents and chemicals stay out of the load. We take the furniture, boxes and appliances around them, from ${min}.
