    All commodities are unloaded at the tipping area and then loaded into a hopper to be fed into the MRF. *Material is first pre-sorted to remove all materials that we do not recycle. Examples are common household items that are not recyclable such as coffee makers and fans, as well as wood, trees, food etc..*After the trash is sorted out, the material passes through an OCC screen. The OCC screen separates the cardboard from other material by guiding it across many rollers that are spaced far enough apart for other material to fall through as the occ glides across the top. The separated occ is dropped onto a conveyor which leads to the collection point for the occ. *The material that drops through the OCC screen is then fed into the scalping screen and glass breaker. Glass falls through a series of decks composed of metal rollers to crush the glass into tiny pieces as it falls. The crushed glass is fed to a conveyor which leads to its collection point. Before it is collected, a cyclone blower cleans the glass by collecting paper mixed in with the glass. The scalping screen guides all other non-glass materials across the top to another conveyor. *After the occ screen and the scalping/glassbreaking screens, the material is passed through two different screens, with the goal of removing as much newspaper as possible. Non-news material falls through the screen to conveyors underneath. *The Newspaper is hand sorted after going through the screens to remove excess material. *The optical sorter separates PET (soda bottles mainly) from other materials by shooting jets of compressed air at the PET that passes through. A photodetector (light sensor) sees how much light reflects off of an object and accepts it or rejects it depending on how much light reflects off the object. A two liter of dr peppper shown in this picture. *After the material has run through all of the screens, it is fed up to the main sorting line where the rest of it is hand sorted and dropped down into separate bunkers depending on the commodity. *An eddy current is used to separate the aluminum cans from other material. It creates a magnetic field that propels the aluminum over the trash shoot to the aluminum bunker. Eddy Currents are electric currents induced within conductors by a changing magnetic field in the conductor. These circulating eddies of current have inductance and thus induce magnetic fields.*The bunkers are emptied onto the conveyor that leads to the baler*An aluminum bale*Loaded trailer of boxboard cuttings*Left side: aluminum cans, milk jugs.
