Can you throw away old paint?

You can throw away old paint but how you dispose of it depends on the type of paint and your local regulations. It is best to try to find a paint recycling program so the paint can be used for some other project and not wasted. If that’s not possible, tip latex paint into a plastic container lined with kitty litter or paper scraps, then let it dry and toss it into the trash. (However, if the latex paint is really old, like 1980s), take it to the hazardous waste facility as it may contain toxic chemicals.) If it’s oil-based paint, take it to a hazardous waste facility. The steps for dealing with both types of paint are explained above.
