Abstract: The invention relates to a sewage pit (1, 60) for receiving and discharging waste material, particularly domestic, medical and/or industrial waste comprising liquid and solid constituents, to the sewer (52), the sewage pit comprising: —a housing (2, 3, 4) with a closable receiving space (9), wherein one or more of the walls of the housing is provided with at least one inlet (19) configured to carry the waste material into the receiving space, a flushing liquid feed (10) which is embodied to feed flushing liquid to the receiving space for bringing the waste material into suspension, and at least one outlet (29) which can be connected to the sewer and is configured to discharge the mixture of waste material and flushing liquid from the receiving space and to the sewer, —at least one pump (25, 26) connectable or connected to the one or more outlets which is configured to pump the mixture which has been brought into suspension from the receiving space and to discharge the mixture via the one or more outlets.

Abstract: Method and system for treating a waste stream. The waste is presented in containers, such as chamber pots and other containers for liquid and other kinds of waste. such waste can be supplied at different locations and is immediately comminuted. In a separating stage, the waste stream is separated into container material and actual waste. Actual waste is fed to a bioreactor where the water is purified so that it may be re-used, if desired. If biodegradable, the container material may be subjected to a fermentation step. Heat and gases released in the process may be used for heating 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 leaving 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.
