This paper describes out the present status of generation, on-site handling, processing and storage of industrial waste in Tehran. In this investigation, 67 large scale factories of different industrial groups were randomly selected. Above cited functional elements of these factories were surveyed. In this investigation a close contact with each factory was required, thus a questionnaire was prepared and distributed among these factories. The relaionship
between daily weight of the industrial waste (Y) and number of employer of each factory (x) is found to be Y=547.4+0.58x. The relationship between daily volume of industrial waste (V), and daily weight of waste generated in each factory (Y) can be described by V=1.56+0.00078Y. About 68% of the factories have
their own interim storage site and the rest of the factories do not possess anyon-site storage facility.
