Develop a PFD(Process Flow Diagram) to separate cardboard, paper, plastics, glass by color, and ferrous metals from commingled waste that has the composition given in Table 3-4. Your flow diagram should incorporate the use of a trommel screen and one or more magnetic separators.

TABLE 3-4 Typical physical composition of residential MSW excludinn ranualan hazardous wastes. b Twenty percent of the households in the United States are assumed to have food waste grinders. Additionally, it is assumed that the percentage of food waste ground up and discharged with wastewater is 25 percent. Current (1990) recycling rate for the United States assumed to be 11 percent.
