Evaluating the quantity and composition of solid waste generated in Kashan during 2009-10

Solid waste management is considered to be one of the most immediate and serious environmental problems confronting urban governments in developing countries. Qualitative and quantitative variety of waste composition, uncontrolled urban development and the lack of appropriate waste management technology cause particular problems that solving them needs a careful study and the coordination of science and experience in the form of a proper management. This descriptive study was carried out on solid wastes generated in Kashan over a limited timeframe of 12 months during 2009-10. One sample was randomly taken per month according to the standard instruction and subsequently the physical analysis of it was performed. The average daily waste generation rate in Kashan is 185 tons, of which 75.5% are putrescible materials. The average daily waste generation is tantamount to 638 g/capita while the average density of the waste was 194 kg/m3 at transfer station. The most frequent metal measured in the leachate solid waste was iron. According to the results, high percentages of solid wastes in Kashan were allocated to plastic and corruptible materials, and then the paper and cardboard. Considering that the prevention of adverse environmental effects of solid waste is a priority and applying proper management techniques can help to achieve this, public education for the waste separation at the source, waste reduction and subsequently reduction of the leachate volume as well as the proper manner of recycling, collection and disposal of the waste are recommended.
