If you're wondering what to do with old paint cans, you're not alone. It's important to dispose of them properly to avoid contaminating the environment and causing issues for sanitation workers. The disposal method will depend on the type of paint and where you live. For example, oil-based paints should be taken to a household hazardous waste collection site, whereas latex or water-based paints can sometimes be disposed of with regular trash, but only once they are completely dried out or solidified. If you're not sure whether the paint is completely dry, it's best to treat it as hazardous waste. Other options for paint disposal include recycling, donating to local charities or shelters, or offering it for free online.

Proper disposal of latex paint
Alternatively, you can pour the paint into a lined cardboard box or trash can. If you have more paint, pour it in layers of about an inch, waiting for each layer to dry before adding another.

Before disposing of latex paint, always check your local regulations as rules vary from city to city. Some municipalities may prohibit old paint disposal, while others have specific paint stewardship programs or hazardous waste collection days.

Disposing of oil-based paint
Oil-based paints are considered hazardous household waste and cannot be poured down drains or solidified and placed out with the trash. Therefore, it is important to dispose of them thoughtfully and carefully.
If you have oil paint that you’d like to dispose of that hasn’t been mixed with a solvent, spread the paint onto some paper waste (such as a newspaper), loosely roll it up, and leave it to dry in a well-ventilated space. Once the paint has hardened, you can dispose of the paper with regular household waste.
If you have mixed oil paint with a solvent, you should store the paint in an airtight metal container before disposal. Once you’re ready, take the container to your local disposal centre. Ensure your container is definitely airtight if it’s travelling inside your car, and make sure there is good ventilation.
If you have a large amount of oil-based paint, you can take it to your city or county's hazardous waste facility. Many cities also host hazardous waste drop-off events at least once a year.
Alternatively, you could donate your leftover paint to a local shelter, drama club, children's charity, or scout troop.

Drying paint before disposal
If you have a small amount of paint left in the can, you can simply remove the lid and let the paint dry out on its own. Place the can in a location where children or pets cannot reach it, and let it sit for a few days. You will know the paint is dry when it is no longer wet to the touch and has a solid consistency.
For larger quantities of paint, you can speed up the drying process by adding absorbent materials such as cat litter, sawdust, or shredded newspaper to the can. Stir the mixture until it becomes semi-solid, and then let it air dry. This method is especially useful if you are dealing with water-based or latex paint, as it helps to solidify the paint and prevent spills during disposal.
If you are disposing of oil-based paint, it is important to note that it is considered hazardous waste and must be handled with caution. Oil-based paint can release flammable fumes as it dries, so it is crucial to work in a well-ventilated area and follow your local guidelines for hazardous waste disposal. Some localities have specific drop-off sites or collection days for hazardous waste, so be sure to check with your local waste authority.
Once the paint is completely dry, you can dispose of it in your regular trash. You can also dispose of the absorbent material, such as cat litter, by placing it in trash bags and throwing it into the regular trash. Remember to review your local guidelines and regulations for paint disposal, as they may vary depending on your location.

Local disposal regulations
In some cities, latex paint is also classified as hazardous waste and must be disposed of accordingly. This is because wet paint can contaminate the garbage and cause issues for compactors, garbage trucks, and sanitation workers. Therefore, it is crucial to ensure that any paint you put in the trash is completely dry. One way to do this is to leave the paint can open for several days until the contents are dry. Another method is to mix the paint with kitty litter or a commercial paint hardener to speed up the drying process.
If you have a large amount of paint to dispose of, you may need to repeat the drying process multiple times. Alternatively, you can use a paint tray liner or a cardboard box lined with trash bags to contain the paint as it dries. Once the paint is dry, break it up into small pieces and dispose of it with your regular trash. Remember to remove the lids from the paint cans or cut them open so that waste haulers can see that the cans are empty or contain only dried paint.
In addition to proper disposal, you may also consider donating your leftover paint to local shelters, drama clubs, children's charities, or scout troops that can use it for various projects. This helps to reduce waste and support these organizations with their decorating or set-design needs.
