The small weighing house completes the central waste deposit. As a steel box under an oval concrete roof it visibly stands out against the design of the other buildings. It is circled by a band-like steel frame with a tin casing varnished in orange. In contrast to this, the longitudinal sides are made of sound insulated glass. The rest room and the storeroom are concealed behind closed elements.
