As we have stated numerous times over the years: Paint disposal – Oil-based paint should not be placed in the trash. KC Recycling Depot collects oil-based paint. Latex (water-based) paint that is dried may be thrown away in the trash as long as the lid is off. To help latex paint dry, mix equal parts of kitty litter or sawdust into your paint and it will dry quickly.
If you are found to have placed paint in the trash you could be cited and billed for any cleanup that may result from the spillage of the paint.
