The management of medical waste is of great importance due to its potential environmental hazards and public health risks. This study was carried in ١٢ teaching hospitals of Tehran University of medical sciences (TUMS). The goals of this study were initiated to characterize solid wastes generated in healthcare hospitals, to report on the current status of medical waste management and to provide a framework for the safe management of these wastes at the considered hospitals. The methodology is descriptive, cross–sectional and observation and consisted in the use of surveys and interviews with the authorities of the healthcare facilities and with personnel involved in the management of the wastes. The results showed that medical wastes generated in hospitals are extremely heterogeneous in composition. ٤٢% of wastes are collected in container and plastic bag. In ٧٥% of hospitals under the study, the stay–time in storage sites is about ١٢–٢٤ hours. ٩٢% of medical wastes of hospitals are collected by covered–trucks. In ٤٦ % of hospitals, transferring of medical waste to temporary stations is done manually. The average of waste generation rates in the hospitals was estimated to be ٤.٤٢ kg\bed\day<\div>

Waste management for municipal solid waste is considered a public health services, providing citizens with a system of disposing of their waste in an environmentally sound and economically feasible way. The amount and composition of waste generated comprise the basic information needed for the planning, operation and optimization of waste management systems. In this study, paper and plastic quantity changes in the MSW (municipal solid waste) of the region ١٠ of Tehran city in ٢٠٠٩ were evaluated. This study was conducted in ٦ months, in the summer and autumn seasons of ٢٠٠٩, at the region ١٠ of Tehran city. In this study, paper and plastic in the solid wastes were segregated and analyzed by SPSS software. The paper parameter of solid wastes was consisted of folder paper, cut board and used newspaper. The plastic parameter of solid wastes was consisted of plastic materials, plastic house shoes, plastic sack, nylon sack, linoleum, radiology photograph and PET. Samples were collected and weighed daily. The total quantity of paper and plastic portion of this region solid waste were ٢٠٣٩٣٠ Kg and ١٨٠١٠١ Kg, respectively. The percentage of paper and plastic portion of this region solid waste also were ٦.٨٢ and ٦.٠٣, respectively. The analyses showed a significant difference between these parameters and season, some months and days (P–value<٠.٠٥). So, because of the results of this study and economical issues, the paper and plastic segregation from generated source point and recycling them are important.<\div>

The objective of this research was to study the quality and compare the compost product of Khomein and Tehran compost facilities. For investigation the chemical quality of these materials, some indices such as organic materials, carbon, nitrogen, phosphorus, potash and heavy metals which consisting of lead, cadmium, mercury and chromium were measured. Microbial quality of samples was defined by assessing the amounts of coliforms, salmonella and parasites ova. The average amounts of considered parameters of Khomein and Tehran composts were: organic materials (٣٧.٧٧, ٢٩.٨٠%), carbon (٢٢.١٤, ١٨.١٢%), nitrogen (٢.٠٨, ١.٦%), lead (٢٢٩.٦, ٥٩.٤٤ ppm), and chromium (٧٠.٢, ١٩.٧٥ ppm), respectively. The microbial quality of these compost samples were in agreement with compost class B. This study showed that organic materials in Tehran’s samples were better than Khomein’s samples, but these parameters were lower than compost class ٢. The carbon, nitrogen and potash percents in these samples were desirable but, phosphorus was not in sufficient. The heavy metals concentration especially lead and chromium in Tehran’s samples were higher than Khomein’s samples, but these samples were usually in agreement with guidelines of compost. Due to the defined microbial qualities, these composts could be used as amendment agents for poor soils<\div>
