FUNCTION Area where the waste transported by collection vehicles to the sorting plants is unloaded and stored. DESCRIPTION These are large covered and closed spaces, with the exception of the access gates. They are connected with the treatment building where the sorting equipment is housed through the first equipment, the primary feeder. TYPES These areas are classified into two types: • Reception pits provided with gantry crane and grapple hook. • Reception yards for handling with loading shovel. For package sorting plants with standard characteristics and capacity, the unload yard or are reception system is considered. If the treatment capacity of the facility is high (6,7 and 8 t/h) or if it is combined with “remainder fraction” treatment plants, the reception and storage type is generally an unload pit for packaging adjoining the conventional pits of the remainder fraction treatment plant. Depending on the primary feeder position, various alternatives to these two types can be obtained. Reception and storage CHARACTERISTICS • The design of the unload yard or storage pit is such that the average storage volume is two days of production, in order to solve potential stoppages in case of jams, breakdown, power outages etc. • To avoid undesired collisions of the trucks and feeding shovel, the unload area must be free of any intermediate supporting columns. The shovel and truck manoeuvres and construction costs recommend an optimum minimum width of 25 to 30 metres without columns. • The unload area must have access gates that can open for the collection vehicles.
