Waste Management in megacities is one of the most relevant issues around the world due to its environmental impacts and economic costs. In this work, we evaluate the application of the theoretical-methodological framework provided by Social Metabolism and Material Flow Analysis to analyze the Municipal Solid Waste Management in the Autonomous City of Buenos Aires (Argentina). The quantitative results evidence that 46% of the city's waste was disposed of in landfills outside its geographical limits, transferring environmental costs to the population on the outskirts of the city and other administrative jurisdictions. The city recycled the other 54% of the waste using different strategies like green centers for recyclable domestic waste (operated by 5500 registered Urban Recyclers/waste pickers recover), a Plant for treatment of pruning activities waste, a Plant for the treatment of construction and demolition waste, and a Mechanical-Biological Treatment Plant. Also in the city work, approximately 5000 informal waste pickers contributing to recycling waste. The approach shows the importance of the inclusion of waste pickers in the formal recycling system, and the failures of costly and inefficient large-scale technologies, as the Mechanical-Biological Treatment Plant. Also, the application of Social Metabolism and MFA allowed a characterization of the flows and processes that make up Municipal Solid Waste management in the area of study, despite the lack of systematized quantitative information. It facilitates a holistic visualization of waste management in the city for decision-makers.
