Most nail polishes contain hazardous materials such as formaldehyde. This means that most nail polishes need to be disposed of as hazardous material to avoid contaminating the environment. Following these simple steps will allow you to safely dispose of nail polish.
Pour the polish onto newspaper. Allow the polish to dry completely out of the reach of children or pets.
Leave the lid off of the nail polish container, and allow the remaining contents to dry out.
Dispose of the newspaper, brush, and the nail polish bottle in the regular dustbin when they are dry.
Dispose of old nail polish by taking it to your local hazardous waste treatment facility. If you have large amounts of polish to dispose of, you may be able to contact your local hazardous waste treatment facility to pick it up.
Contribute your old nail polish to a woman's shelter. It can be thinned out with polish thinner and used by the women who may not be able to afford or may not have access to such beauty items.
Instead of using newspaper, you can pour the polish into another disposable container and allow it to dry.
Do not simply throw away bottles of nail polish because they can contaminate the earth and are very flammable. Do not pour old nail polish down the sink or toilet because this can contaminate the waterways.
