“…The waste statistics are derived from the official statistics when modeling of the total Municipal Solid Wastes is required (e.g., Beigl et al, 2004;ParWtt et al, 2001;Hockett et al, 1995;Chen and Chang, 2000) or the sum of all recyclables (ParWtt et al, 2001) or single recyclable materials, like glass, plastics or metals or paper and cardboard (Bach et al, 2003Lebersorger et al, 2003 or single collection streams, like residual waste (Mertins et al, 1999;Grossman et al, Dyson and Chang, 2005;Jenkins, 1993;). Some of the models also address other ways of disposal of wastes, like private wiring, illegal disposal and informal collection, other than the officially reported waste streams.…”
