How do you dispose of Glow Sticks and are they safe?

One of the disadvantages of using glow sticks is that there is no environmentally safe way that you can recycle them. As each one has chemicals inside, the plastic casing cannot be reused nor can it be repurposed. 

The reason why glow sticks produce light is that there are two main ingredients that cause a chemical reaction.

Although the casing is made of strong plastic, be careful of young children or pets chewing on the plastic. Although the chemicals are not that toxic, it is not advised to ingest them. If a child swallows some of the chemicals, make sure to rinse his or her mouth immediately. Speak to your doctor if the child has swallowed a lot.
