Use good machinery and use it well • Simple technology and materials handling: • Avoid over compacting cans or cans and plastic fractions during collection • Tipping loose cans into wire baskets helps to filter out smaller contaminants, e.g. glass, and can make visual inspection easier • Controlling the rate of flow along conveyors with chains • Fit grilles in holding hoppers • Set conveyors at a high angle so that heavy objects fall back • Ensure eddy currents are well positioned and sufficient for the volumes handled • Check the positioning of skips. Use marks on the floor to ensure they are always replaced correctly after emptying
Use good people and treat them well • Housekeeping: • Ensure balers are cleaned to remove traces of other materials (e.g. paper, plastic) before baling of UBCs starts • Check the settings on eddy current separators regularly; for example is the splitter plate set to give the maximum sort? • Pay regular attention to the cleaning of floors, skips etc. This not only reduces the opportunity for contamination to occur, it is also an important aid to maintaining health and safety in the work environment and improving staff motivation. • Staff training: • Your staff are the key to successfully cutting contamination • Contamination can be prevented by staff being more aware of the potential problems, and understanding the need to be vigilant
Open loop ‘multi-material’ collection and sorting schemes In general it is difficult (and costly) to separate the small aluminium fraction from multi-material schemes. Therefore it is recommended to separate it early in the sorting process which in combination with improved separation techniques will result in higher yields, better quality and more value. There is the additional advantage of higher consumer involvement . Glass household waste, including paper + ‘light fraction’ = plastic bottles (PET), metal containers (beverage cans, etc.) and beverage cartons (if necessary) Glass Paper + Light fraction Glass Paper fraction Light fraction
