Cuprous oxide is made from copper, and it can be used as a pigment or fungicide. It is an unstable compound, so it should not be used under stress. However, it is also used in a variety of other applications, including as an antifouling agent. To avoid getting sick, it is important to know all of the precautions that you should take when handling it. Some of the main things to keep in mind are the dangers of inhaling it and the proper methods for disposing of it.
As far as disposal goes, you can either dispose of it at a waste disposal facility, or you can recycle it. The process for figuring out how to recycle your cuprous oxide can vary depending on your state. You may need to consider the environmental regulations that your state has, as well as federal disposal rules. Depending on the amount, you should store your cuprous oxide in a cool and dry place. If you have a large amount, you may want to contact your local government to learn more about the recycling options that are available to you.
