Latex paint must be dried up before collection. You can either mix it with kitty litter until solidified or you can brush residual out on a plywood board.
Environmental Recycling, located at 527 E Woodland Circle in Bowling Green, will accept latex and non-latex, old and new paint for proper disposal. This business charges a fee for disposal, so you may want to call first for rates. The contact number is 800-284-9107.
