Urban Waste Management with an Emphasis on Reducing Greenhouse Gas Emissions from the Source Using IWM Model (Case Study: 15th Urban District of Tehran)

Disposal of urban waste contains pollutants whose quantity and diversity multiplies every day. This process, while requiring appropriate management, should be done in a way that minimizes greenhouse gas emissions. In this research, after considering the quantity and quality of waste in the 15th district of Tehran and its current disposal method, four scenarios were considered studying the facilities, recycling, compost, and also a reduction of 5% of waste materials from the source. Then the scenarios were analyzed in terms of the production and emission of greenhouse gases using the IWM model. The results indicate that recycling and compost facilities play a significant role in reducing the greenhouse gases. By reducing 5% of waste per year, 401.66 tons of CH4 NOx and 6132.36 tons of CO2 gas have been decreased on average in one year.In general, it can be argued that the use of facilities such as recycling and compost, as well as using the principle of reduction from the source by culture-building for the general public, can reduce environmental problems and in particular lower the greenhouse gas emissions.
