We used to repair electric motors for the local council in Liverpool. Went to pick a job up one day and was talking to a couple of guys about recycling etc and the extra work it creates sorting it out. I was 'informed' that any programmes you see on TV of workers at a transfer station/tip is just propaganda. No such jobs exist(ed) at that time with the exception of glass pickers. Any refuse collected each week goes through the same processes. The waste is taken to a transfer station, it is dumped and then fed on to conveyors, any bags are automatically split open to expose the contents. As the belts move forward they pass under magnetic belts which draw up ferrous metal, (which may also pick up other items with metal attachments such as wood/plastic etc), they then go through light blowers which blow off things like loose paper, tissues etc. Broken glass is left on the belt but intact bottles, glasses etc are now picked off by hand and thrown in bins next to the operators. Non magnetic metals such as brass/alloys etc usually stay on the belts after the have passed over screening mesh to let smaller things fall through. Cardboard is blown off by stronger blowers, (though lighter bits often get blown off with the paper).
All the ferrous metal is sent to a scrap yard for shredding if the depot doesn't have it's own shredding machine. The shredded metal, (usually small pieces about 1" square are then shipped to places like China for reprocessing. The paper/cardboard is sent to the paper mills and plastics are shipped abroad for recycling as we do not have the facilities in this country.
Inevitably a lot of the waste slips through and still ends up in landfill but there is no necessity to wash things out because, as someone said earlier, anything that is recycled goes through various processes such as washing, heating, firing etc that contaminants are either skimmed off the top or drained from the bottom.
