62-63 • 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 considered necessary, depending on plant capacity, to store aluminium (if it is not collected in a buffer conveyor) and empty it in a metal press bin. In addition, open containers from 25 to 30 m³ are needed to store bulky material and bales of aluminium and steel. • Rejected waste material management system. For capacities under 5 t/h it is considered optimum to install two autocompactors 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 building with a minimum surface area calculated for two and a half deliveries of each material, approximately 180 m2.
