In combination with the composition of input waste stream and elemental analysis of waste components, specific load contribution of various elements in unsorted waste stream (i.e. input waste stream of C&IW) was determined. In order to calculate the specific load of an clement in input waste stream. the mass fraction of that component in input waste stream was multiplied with the concentration of the element in that component of input waste stream. Composition of input waste stream is published in a previous study [21] and concentration of elements is taken from elemental analysis of components (see Table l). The specific load contribution of an element in the components of input waste stream was based on the weight % of component (on dry basis) in the waste stream and concentration of element in that component on dry basis as well
