According to the present invention waste 7 is dried by applying the waste 7 to a floor 4 comprising several floor segments 34, 44, 46 and by conveying the waste 7 by a push floor mechanism in which only a part of the floor segments 34, 44, 46 is moved at a time in a direction of movement 8 or a counter direction 61. The energy for drying the waste 7 is provided by warm air 11 through openings 38 in the floor segments 34, 44, 46 from a pressure chamber 3 through the floor 4 into the waste 7 and through the waste 7.
