hazardous waste

Industries play an important role in the development of societies. The generation of large volumes of industrial waste with complex characteristics makes their management a challenge. In addition to occupying the land, the accumulation of these wastes causes environmental pollution. The main purpose of this study is to identify industrial wastes in the industrial zone of Gilan province and to investigate their management system. In this study, 11 industrial zones in Gilan province were investigated in 15 industrial groups. Astara industrial zone has the lowest number of units with six active units, and the largest number of active units under investigation is Sepidroud industrial zone (41 units) and then Rasht industrial zone (37 units). The food industry group with 50 active units (24%) has contributed the most in investigating the type and amount of industrial waste in Gilan province. Based on the data of the study, the total amount of industrial waste is 45926 tons per year. In addition, the main special genaration wastes are 60314 liters of used oils and 16707 tons of different types of wastes per year. The metal industrial group generated the largest amount of industrial waste with the genaration of 32917 tons per year. Also, the cellulose and synthetic oil industrial group units have the highest amount of hazardous waste genaration per year with the genaration of 29,600 liters and 6,300 tons, respectively. Based on the data obtained from the industrial units, the total sales and recycling methods accounted for 54.1% and disposal for 45.9% of cases. Obtaining information on industrial waste flow in Gilan province provides the opportunity to recover and save identified resources. In addition, many economic and environmental benefits are obtained by making a decision and implementing proper waste management.

In the metropolis of Tehran,hazardous household waste is buried due to lack of proper management without taking any action on it, such as separation at the source of separate collection of recycling and recycling along with other burial waste in the processing and disposal complex Aradkou. In this research,it is tried to study the strategies, facilities and equipment used in the management of hazardous household wastes in different countries that are facing in this regard and study the current trend of solid urban waste streams in Tehran according to the governing system.On waste management in Tehran city and the location of hazardous household wastes in this regard,considering that the reduction of production and separation of waste at source would be of great help in recycling and eventually sanitizing them and preventing pollution of the environment and the loss of national capital After identifying the weaknesses and shortcomings in the c The procedures, including the vacuum, of the legal requirements,the lack of facilities and equipment for recycling and processing,as well as the executive directives on the management of hazardous household wastes, should be addressed in the formulation of strategies and strategies for the management of hazardous household wastes in Tehran
