Abstract: A method and an apparatus for sorting waste into different waste types. A first division of the waste is effected into at least two waste types in that each waste type is placed in a bag or container (100, 101) which is provided with at least one marking which indicates the waste type for which the bag is intended. The containers are collected and mixed together for transport to a common sorting plant in which the containers pass an identification mechanism (6) establishing, with the aid of the marking on the bag, the type of waste for which the bag is intended. The information is transmitted to a recording and control system (7) which, via a signal transmission device (73) switches a separating mechanism (9) for adjusting the same into a position in which the bag, on its passage of the sorting plant, is brought into a position reserved for that type of waste indicated by the marking on the container.
