Abstract: 

The increasing development of stone cutting industries (SCIs) and the extensive use of the different types of stone for construction have led to the increased amount of generated solid wastes in our country, which requires proper environmental management. Considering the importance of the issue, the management of SCIs solid wastes was investigated in Qom province as a case study. Some 55 SCIs were selected and studied. Meanwhile, the disposal sites of the SCLs solid wastes were surveyed as to their environmental adverse effects.
The results show that there are 186 active SCIs active in Qom Province, all of which are located within at most 15 kilometers from the city of Qom in 4 areas: Kooh-e Sefid road, old Qom-Tehran road, Kashan road, and Isfahan road. The generated solid wastes are disposed of in 4 sites along these roads. Regarding the number of stone cutting machines (SCMs), these industries are of two types: 151 units have one SCM and 35 units have two. As to the frequency of such factories, most of them (77 units) are along Kashan road. On the average, 50% of the stone used in these factories changes into waste material. The highest amount of waste is related to quarts stones and the lowest pertains to granite stones. The SCIs having one SCM produce an average of 400 tons of wastes per year. The figure is about 600 tons per year for two-SCM units. The total annual amount of solid wastes generated by SCIs is estimated to be 81,400 tons, of which 15,000 tons (18%) are recycled. For complete recycling, the capacity of these factories should increase at least as much as 500 percent. There was no proper management at the disposal sites; therefore, it is necessary to take correct actions for the collection, recycling, and disposal of these waste materials by responsible organizations including the municipality.
