Saturday afternoon at Solvay Employee Park, more than 700 people dropped off some hazardous household wastes.
The waste collection happens every two years across Southeast Ohio.
Anything from pharmaceuticals, batteries, motor oil, cleaning agents, and pesticides were among the items dropped off to be properly disposed of.
Organizers say the collection is a safer alternative to throwing those chemicals in your trash.
"There's materials in here that are considered oxidizers so if they're mixed with the wrong material they can create a fire or explosion. We have chemists on site that separate those materials", says Robert Reiter, District Coordinator Southeast Ohio Joint Solid Waste Management District.
Reiter says those chemists take a lot of precautions when handling a large amount of hazardous materials like these.
Another collection is happening in Zanesville on August 2nd.
