Hazardous waste day in Dedham, MA

Household hazardous waste boxed in a plastic crate in a garage: paint cans, jugs, batteries and fluorescent tubes

The 2026 collection and the next one

The 2026 collection guide lists the day as Saturday, July 25, 2026, 9 a.m. to noon, in the DPW parking lot at 55 River Street. The town says it offers free household hazardous waste collection events throughout the year, run by the Health Department and Public Works, and that dates are added to the page and the town calendar as they are announced. Nothing is announced for the rest of 2026 or early 2027. The Health Department page still shows October 4, 2025 as its "next" date, which has passed. Call 781-751-9220 (Town Hall, third floor, 450 Washington St) or the DPW at 781-751-9350, and sign up for the town's email alerts so the date reaches you.

The 2025 day was free for residents with proof of residency, with a disposal fee of $25.00 per unit for TVs and computer monitors, cash or check payable to the Town of Dedham. The 2026 guide says its events are free for residents and need proof of residency, and does not list a TV fee.

What it takes and what it refuses

The town's hazardous waste page lists what the collections take. Automotive: motor oil and filters, antifreeze, brake fluid, gas and gas mixtures, automotive batteries, car waxes and polishes. Paints and solvents: oil-based paints and stains, thinners and strippers, varnishes, aerosol paints. Garden: insecticides, herbicides, weed killers, rat poison. Cleaners: oven, drain and toilet bowl cleaners, furniture polish, bleach and ammonia. Also pool chemicals, mercury thermometers and thermostats, fluorescent bulbs, rechargeable and button batteries, propane tanks and fire extinguishers.

Not accepted: latex paint, alkaline batteries, prescription medications, sharps and medical waste, asbestos, radioactive materials, smoke detectors and appliances. The town's advice for latex paint is to dry it out and put it in the regular trash. Alkaline batteries and smoke detectors also go in the trash.

The July 25 flyer in the 2026 guide was narrower: it listed fire extinguishers, motor vehicle batteries, propane tanks and tires as not accepted at that event. So confirm the list with the Health Department when a date is posted. Tires, lead acid batteries, motor oil, fire extinguishers and 20-pound propane tanks are taken at the monthly DPW Saturday (see Dedham DPW Saturdays). Appliances go by appointment with Boston Carting at $41.42. Sharps are a separate program: residents can drop them off at the Health Department during Town Hall hours, in an FDA approved sharps container.

Holding it until the next date

Keep products in their original labeled containers, tightly capped and sealed so they cannot leak, in a box or crate. Store them in a cool, dry garage or basement shelf, away from the furnace, water heater and children. Never mix products, and do not pour anything down a drain or onto the ground. Old gas goes in an approved can with a tight lid. If you are clearing a house, move the containers to one shelf so the rest of the cleanout can proceed.

JunkRun cannot take hazardous waste. We clear everything around it: furniture, boxes, appliances and the rest of the garage or basement. A full trailer is $519, a half $319 and the minimum visit is $159. Tell us when you text what is on the shelf, and we leave it set aside for the collection.
