Five thousand pounds of hazardous waste which may have ended up being improperly disposed of in Warren County was collected Saturday.“The idea is to keep this stuff out of the landfills and streams,” said Patrick Story of Clear Harbor, the company contracted to collect hazardous waste for the state of Tennessee. “We collect roughly 3,000 to 5,000 pounds from Warren County per year.”Clear Harbor conducts two or three collection events each weekend at various towns across the state. Saturday was Warren County’s single collection day, the event held at Three Star Mall parking lot.“We mostly see things like pesticides, motor oil, antifreeze, detergents, and light bulbs,” Story said, noting the items should not be thrown out with regular trash since they pose environmental hazards.
