Rapidly growing population coupled with technological developments consistently increases the amount of solid waste in cities. Therefore, city authorities need to develop an optimum option to deal with their solid waste. The project area of this study is Istanbul, which has the highest-population in Turkey with almost 15 million locals. This study aims to specify the status of municipal solid waste management in the province. For this reason, a model was developed by adopting a methodology called “Materials Flow Analysis”. The information and the data gathered from the institutional databases, published reports and the literature were used to feed the materials flow model. It was found that almost 79% of the total municipal waste is sent to landfills while 21% is recycled or recovered. Most of the waste produced in the city enters the flow through the waste landfilling rather than recycling or recovery. It was also found that the contribution of informal waste pickers into the recycling system is not small as they can segregate almost 14% of the waste which enters the collection system. On the other side, waste segregation practiced by locals by the incentive of the municipality is only 6%, which is much smaller than the efficiency of informal recycling.
