This Saturday, Nov. 17, is the last day this fall on which Boston residents can drop off household hazardous waste to be disposed of for free. 

Residents may bring up to 50 pounds of products labeled toxic, flammable, reactive, corrosive or poisonous, such as: oil-based paint, motor oil, pesticides, solvents, glues, bleach or ammonia-based cleaners, weed killers, photo chemicals, pool chemicals, car batteries and used motor oil.  

Note: Latex or acrylic (water-based) paints are no longer accepted at hazardous waste days. They are not hazardous and can be safely disposed at home. Other items that won't be accepted are: asbestos, explosives, medical waste, fire extinguishers and TV and computer screens. See this flyer for a full list. 

Residents must show proof of Boston residency before they will be allowed to drop off any items. 

The hazardous waste dropoff location on Saturday is at the West Roxbury Public Works Yard, 315 Gardner St., West Roxbury, from 9 a.m. to 2 p.m.
