Residents can safely dispose of old car batteries, oil, paint and other household hazardous waste free of charge when the Wastemobile continues its 22nd year of service with a stop in Bothell Sept. 9-11.

The Wastemobile will be in the parking lot of the Seattle Times building at 19200 120th Ave. N.E. and will be open from 10 a.m. to 5 p.m. each day.

“This service is a safe, easy and convenient way for all residents across King County to dispose of their household hazardous waste,” said Jay Watson, program administrator. “There is no charge to drop off these unwanted products, because residents already pay for this service through their garbage and sewer utility bills.”

Created in 1989, the Wastemobile was the first program of its kind in the nation. It is operated by King County Solid Waste Division as part of the Local Hazardous Waste Management Program, and travels throughout the county from the spring through fall.

Since its inception, the Wastemobile has collected more than 14,000 tons of hazardous household waste from 333,000 residents.
