Household Hazardous Waste Disposal

Household Hazardous Waste
Household hazardous waste (HHW) is any product labeled as toxic, poison, corrosive, flammable, combustible, or irritant that is disposed. A typical home can contain a vast array of HHW from products used for cleaning, painting, fertilizing, lubricating, and disinfecting the house, pool, yard, workshop, and garage.

The City recommends three action levels: 1) use it up, 2) clean it up, and 3) dispose of it properly.

FREE and Convenient Curbside Pick Up: The City's franchise haulers are required to offer free curbside pickup of HHW as part of the City's refuse collection agreements.  Waste Management and Valley Vista are the two franchise haulers that service the Diamond Bar community.

  • Valley Vista: Residents that receive refuse collection service by Valley Vista can schedule a free HHW curbside pick up by calling 800.442.6454

Acceptable materials to bring to a roundup include most paints, glues, solvents, cleaners, batteries, pesticides, pool and photography chemicals, oils, and fuels. Items should be securely contained and clearly labeled before taking them to a roundup. Under no circumstance should you ever mix materials. Explosives, ammunition, radioactive materials, regular trash, waste from businesses, and tires will not be accepted at a roundup.
