Tennessee environmental officials say crews will be in Fayette, Hamblen and Roane counties this weekend to collect hazardous waste.

The Tennessee Department of Environment and Conservation says its mobile household hazardous waste collection units will be in the three counties on Saturday.

There is no cost or appointment necessary, and a person does not need to live in the county to participate, the department said in a news release Monday.

Drop-off locations are at the Fayette County Landfill in Somerville, Hamblen County Solid Waste in Morristown and Roane County Recycling Facility in Harriman.

Among the items eligible for disposal are cleaning fluids, pesticides, mercury thermometers and thermostats, fluorescent lamps, lithium and button batteries, aerosols, adhesives, medications, brake fluid, swimming pool chemicals, paint thinner and used needles in sturdy containers, the department said.

Ineligible items include ammunition, explosives, alkaline batteries, paint, electronics and empty containers that should be discarded in normal trash, officials said.
