The question is about the type of waste that should be recorded when a pharmacy's compounding process consistently yields more drug than is needed. This excess is stored until it is used or expired. In the context of waste in healthcare, this scenario is a clear example of overproduction.
Overproduction refers to situations where more product is produced than is required at that time. This is a form of waste because it leads to unnecessary storage and potential disposal if the product expires or becomes obsolete1.
