Abstract: A diaper system for infants including a disposable, biodegradable inner insert and a reusable, washable outer cover. The insert is disposed next to the baby's body and absorbs liquid waste and captures solid waste. The cover holds the insert securely in place on the infant and serves as a backup for retention of liquid and solid waste. Periodically, the system is changed whereby the cover is removed, the insert is then removed from the infant and disposed of in garbage or the like, where it later biodegrades. The baby is cleaned and a fresh insert is applied. The same or a new cover is then applied and secured to hold the insert in place. The process can be repeated indefinitely and a relatively small number of reusable covers (for example 2 or 3) can be used, and cleaned periodically, with a larger number of disposable and biodegradable inserts (for example approximately 100 per month). Embodiments of the disposable insert and reusable cover are also disclosed.
