Análise da recuperação de materiais recicláveis: uma aplicação do Propensity Score Matching na base de dados do SNIS

Abstract

This undergraduate thesis aims to assess the impact of the implementation of Muni-cipal Integrated Solid Waste Management Plans (PMGIRS), as stipulated in Law No. 12,305/2010 - the National Solid Waste Policy. The central methodological approach utilizes the concept of Propensity Score Matching (PSM) to explore the causal effect of the presence of PMGIRS on the Recycling Material Recovery Rate. Additionally, the research incorporates the use of k-means clustering with the aim of better cha-racterizing and classifying the analyzed sample. This allows for the identification of natural data clusters and a deeper understanding of different potentials for solid was-te management in distinct municipalities. PSM is employed to create comparable groups of municipalities with and without PMGIRS, balancing observable characteris-tics and controlling for potential selection biases. The results obtained from this me-thodology will contribute to a well-founded and objective analysis of the impact of PMGIRS on municipal solid waste management. Combining PSM with clustering will enhance the analysis, enabling a more comprehensive characterization and precise classification of the studied sample.
