One of the types of environmental pollution is air pollution. Air is one of the most important and valuable resources of nature, and according to the definition, the accumulation of a large amount of particles or harmful substances that causes the reduction of air quality is called air pollution. Today, urban solid waste management is one of the most important concerns of human societies. The increase in the volume of waste as well as their diversity affects the complexity of how to separate and dispose of them. Methane emission from landfills is one of the most important factors of greenhouse gas emissions. Despite the increasing efforts to use methods such as recycling, composting, etc., landfilling of urban wastes continues to be the dominant method for disposing of non-hazardous wastes. The use of landfill site methods affects many aspects not only from the environmental point of view, but also from the economic and social point of view. In order to make decisions more easily and eva‎luate different scenarios in the conditions of simultaneous use of several methods of waste disposal and reduction of budget in relation to social aspects, as well as analysis of costs and income in each scenario, a dynamic model has been used. Compost method has the highest income among the two methods of landfill and waste incinerator, and it has the lowest greenhouse gas emissions in terms of environmental protection. In the context of investigating the cultural aspect of the waste management system, with the increase in the budget in the field of culture, there is a decrease in waste production per person, which caused a decrease in the waste production rate in the population of Tehran.
