Garbage collection and bulky waste
If the garbage disposal is not included in your rent, you should cancel your contract with the waste management company within the appropriate amount of time.
Update: Jan 2014
Check the details of your particular waste management company. In general, you will need a proof of your deregistration in order to cancel, either by a written statement or on the website of the company.
The pick-up of bulky waste is normally also included in the service. Therefore, if you are leaving your flat and there are items which you are not taking with you, you should call the waste management company in time to set up an appointment for the pick-up of any bulky waste.
