Method and system for treating a waste stream in a care institution. The waste is presented in containers, such as chamber pots and other containers for liquid and other kinds of waste. According to the present invention, such waste can be supplied at different locations (2) (departments) and is immediately comminuted (3). This is followed by a separating stage (4) in which the waste stream is separated into container material and actual waste. The actual waste, such as urine and feces is fed to a bioreactor where the water is purified so that it may be re-used, if desired. If it is biodegradable, the container material may be subjected to a fermentation (38) step. The heat and gases released in the process may be used for heating the contents of the fermenter and/or generating power. It is also possible to feed kitchen waste., which may optionally have been comminuted, to the fermentation. The stream which leaves the fermentation may be separated into hard components which are filtered off and composted and into softer components which can be fed to the purification installation (5).
