In a method for managing waste (W) deposited in disposal packages (6-F1, 6-F2, 6-F . . . 6-Fn) and introduced into a vacuum operated waste collection system (1) wherein waste is conveyed through transport piping (3), from waste inlets (2) to a waste collection container (5) for storing waste before removal and wherein the disposal packages carry readable information (7-F1, 7-F2, 7-F3 . . . 7-Fn), disposal packages containing one of multiple waste fractions (F1, F2, F . . . Fn) are received through a common waste inlet, subsequent to identifying each disposal package by comparing read waste fraction information carried thereby and being unique for each fraction, with stored fraction data, comparing the identified disposal packages to a fraction time schedule for matching package information to fraction time schedule time periods belonging to the respective fraction, whereby access to the waste inlet is allowed for each package during the time periods belonging thereto and is blocked for each package at all other times.
