RESUMO:

The management of urban solid waste (MUSW) comprises a set of actions for the planning and development of public policies. This thesis aims to develop a theoretical model to assess the socioeconomic metabolism of solid waste (Socioeconomic Metabolism of Waste, SEMw) through an exploratory study and Structural Equation Modeling (SEM), adopting technical variables (metric) and social variables (not metric) from the GRSU process. The end-of-life tires (ELTs) or scrap tires case study of a city of 300,000 inhabitants was adopted. The first contribution of the thesis work was the development of a database through deductions and exploratory analysis from public sources (Institute of Geography and Statistics (IBGE) and National Traffic Department (DENATRAN)), to carry out a prediction and preliminary diagnosis of the mass balance of ELT flows in the city. The second contribution, which represents the main innovation of the thesis work, was the development of MEE through technical (Direct Material Flows, DMF, and Reverse Material Flows, RMF) and social constructs (Socioeconomic Factors or Socioeconomic Environment, SEF, and Sociodemographic Factors, SDF) to guide GRSU. For MEE, a sampling was performed using a structured questionnaire (with Likert scale) and, later, modeling in the SmartPLS software using the partial least squares (PLS) approach. The results obtained confirmed 70% of the hypotheses presented in the theoretical framework for SEMw evaluation. The model comprises an innovative approach, capable of relating objective (metric) and subjective (non-metric) variables. In the MEE analysis of SEMw, the initial diagnosis of the ELT flows adopted in the mass balance was confirmed, which presents useful information to guide researchers and public managers in the development of scenario analysis procedures related to the generation, management and disposal of solid waste. MEE is an analysis tool that can be adopted to support the execution of the ELT management plan or similar waste management guidelines.
