Household hazardous waste in Sandwich

How the collections work

The county runs a regional program for Bourne, Falmouth, Mashpee, Sandwich and Joint Base Cape. Collections are on Saturdays, town residents participate for free, proof of residency is required, and non-residents must register in advance on the website. The 2026 stops rotated between Sandwich High School on April 18, Falmouth High School on June 20, Mashpee High School on August 22 and the Bourne Landfill on October 17, each 9 a.m. to 1 p.m.

The county says the 2026 season has ended and the 2027 schedule and brochures will be posted in spring 2027. We found no 2027 date for Sandwich. The program line is 1-800-319-2783.

What they take and what they refuse

Accepted: oil-based paints, stains, varnishes and thinners, lawn and garden chemicals, household cleaners, pool and hot tub chemicals, gasoline and automotive fluids, mercury items and lithium batteries. Not accepted: vehicle and household batteries, propane tanks, smoke and carbon monoxide detectors, fluorescent bulbs and fire extinguishers. Latex paint is not hazardous waste, and Sandwich's own Transfer Station lists non-hazardous paints, stains and wood finishes as accepted.

Sandwich's rules sheet adds that cathode ray tubes go to the free annual collections, and the FAQ sends oil or gas soaked rags to one of four annual Upper Cape collections.

Between collection days

Chemicals do not wait well in a garage over winter. Keep them in original containers, upright, away from heat, and write the date you moved them. Do not mix products or pour them down drains: the county's stated purpose is to protect Cape Cod drinking water.

A hazardous-waste day is not a clean-out service. It does not take furniture, mattresses, appliances or building debris. JUNKRUN takes the non-hazardous rest: a quarter trailer is $209, a half $319, three-quarters $409, a full trailer $519, $159 minimum. We do not take paint thinners, pesticides or other hazardous chemicals; put those aside for the county day.
