SORTING PLANT STANDARDS Adaptation of selected material and rejected waste management at 2 t/h plants. • Quality controls for selected materials. In manual sorting plants it is not necessary to perform quality controls on materials that are manually sorted. • Storage silos prior to material compaction. Selected material silos do not need to be automated, as the transport of the material to the press feeder can be performed by hand truck or loading shovel. There must be as many silos as there are selected materials to be compacted in the multimaterial press (PET, HDPE, FILM, beverage cartons and mixed plastics). • Multimaterial press. Used to compact material stored in the automated silos. Depending on the amount of material stored, a forklift or loading shovel will dump its contents on a feeder/doser placed transversely to transport the selected material to the press. • Metal press. As most of the metal present is steel, this is pressed in a continuous arrangement. Aluminium is stored in containers or in a buffer conveyor for separate compaction at the end of the shift. • Film press. In plants with capacity under 7 t/h there is no specific press for this material; the multimaterial press is used. • Containers. Containers from 3 to 5 m3 are needed to store aluminium and empty it into the metal press bin. In addition, open containers from 25 to 30 m³ are needed to store bulky material and bales of compacted metal. • Rejected waste material management system. For capacities under 5 t/h it is considered ideal to install an autocompactor to manage and transport the rejected waste. • Storage of selected materials. For manual plants it is considered that selected and compacted material must be stored in a minimum surface area calculated for two and a half deliveries of each material, approximately 180 m2. 4
