LIGHT WEIGHT PACKAGING SORTING PLANTS 18-19 Scales for monitoring and weighing of collection vehicles Vehicles with packaging waste collected from streets arrive at the sorting facility passing through access control and weighing (scales). In order to transport the collected material more efficiently, when the street collection vehicles need to travel distances greater than 40km from the place of collection to the destination plant, it is convenient to unload the material at intermediate locations (transfer stations) for compacting and subsequent transport in larger containers. In this case the material arriving at the plant has a greater density, which must be considered when sizing the treatment capacity of the facility. Unloading area for transported waste After weighing the vehicles and identifying their origin and schedule, they are led to the covered reception area where the transported waste is unloaded in the area or location indicated by the discharge and feeding operator. Positioning and stacking of unloaded waste The loading shovel stacks the unloaded waste vertically, optimising the surface available for storage prior to treatment. This process can include several components of bulky waste with sizes or shapes (as in mattresses, large packages, bicycles, etc.) that hinder the work and could affect the sorting equipment to be used. Using the loading shovel the operator must place these in a specific container located on this or another surface.
