  • Municipal solid waste sorting system and method
    Publication number: 20090032442
    Abstract: A method, and associated system, of sorting municipal solid waste (120) into types of materials, the method including the steps of: sorting the solid waste (120) into an oversize fraction (180), a midsize fraction (170) and an undersize fraction (160); using at least manual-based (210, 330), density-based (234, 310), further size-based (346) and metal-based (318) sorting means to obtain a partial oversize fraction (236), a first partial midsize fraction (348) and a second partial midsize fraction (350); combining the partial oversize fraction (236) and the first partial midsize fraction (348) to produce an oversize-midsize combined fraction (237), and combining the undersize fraction (160) and the second partial midsize fraction (350) to produce an undersize-midsize combined fraction (412); and, using further sorting means to further sort the oversize-midsize combined fraction (237) and the undersize-mid-size combined fraction (412) into types of materials.
