A device for shredding a waste flow, wherein the waste flow at least comprises solid constituents as well as liquid constituents, the device comprising:

• a housing provided with at least one first inlet for introducing the waste flow, a second inlet for introducing supplementary liquid and at least one outlet for discharging the shredded waste flow with supplementary liquid, wherein the outlet is connected or connectable to a conduit system connected to the sewer system;
• at least one shredding unit arranged in the housing and comprising a shredding element drivable via a drive motor;
• a control unit configured to control at least the second inlet, the outlet and the shredding unit for the purpose of at least partially immersing the shredding element in the mixture of liquid constituents, solid constituents and supplementary liquid, to subsequently activate the shredding unit for the purpose of shredding the solid constituents of the waste flow with the shredding unit in at least partially immersed state and, as soon as the waste flow has been shredded, to discharge the shredded waste flow via the outlet of the housing.
