Where do I take old paint

At the Montgomery County Solid Waste District Transfer and Recycling Facility, 1001 Encrete Lane, Tuesdays, 8:00 am - 2:00 pm or Saturdays, 8:00 am - 2:00 pm. www.mcohio.org/departments/solid_waste/household_hazardous_waste_disposal.php

Do they take styofoam and cardboard

Solid waste transfer will take it

I believe they have a hazardous waste disposal but you may want to call on the cost and where to drop them off. If there is no wet paint left, cans are empty and paint is dry inside and lids are off, you can just throw them away in the regular trash.
