From the Pre-Sort Cabin, material flows on to our OCC Screen. Here, rigid cardboard floats over the screen and after final quality checking is conveyed directly to a dedicated storage bunker ready for baling.
The first section of the OCC Screen is fitted with hardened metal discs, which assist with breaking of glass bottles and jars and ensure that glass is removed from the mixed material at the earliest possible opportunity. The OCC screen discs are sized to separate material into two different size fractions:
The 0-100mm material falls through the OCC Screen onto a Debris Roll Screen (DRS). This DRS screen is sized to separate material of less than 50mm (principally glass and shredded paper) and once extracted this material is transported to our Glass Clean Up System where the lighter non-glass material is removed and recovered, using magnets and aspiration. The glass produced is transported directly to storage bunkers for collection by reprocessors.
The 50-100mm material, which tends to be highly compacted and flattened plastic bottles and tin cans, is conveyed directly to a second DRS screen. Here paper is removed by additional aspiration and any remaining glass is removed by further screening. The remaining plastic bottles and cans enter the Container Sorting section of the system, which is explained in more detail later on.
The 100mm+ material, mostly newspapers and magazines, smaller papers and the un-compacted plastic bottles and cans, flows through the OCC Screen and is conveyed to our NewSorter Screens. These screens separate the newspapers and magazines from the rest of the mixed material. The newspapers and magazines are then conveyed to our De-inking Screen, which removes any rigid paper (light card packaging). The newspapers and magazines are transported to a Quality Inspection Cabin, where material quality is checked and any remaining plastic film (plastic film tends to travel with all material streams and needs careful monitoring throughout the process) is removed. Film is transported by pneumatic extraction to dedicated processing bays. The finished newspapers and magazines are conveyed directly to a storage bunker ready for collection by reprocessors.
