Modelo de maturidade para avaliação de práticas de Economia Circular

Abstract

This dissertation presents a maturity model for assessing Circular Economy (CE) practices in industrial companies. The growing demand for sustainable solutions to contemporary environmental challenges has driven CE as a strategic alternative for decoupling economic growth from the exploitation of finite resources. However, the literature lacks consensus on indicators for evaluating circular practices and reveals limitations in existing models, particularly in their ability to quantify data based on human judgment. To address these gaps, this study proposes a model structured in three dimensions, grouping a set of CE practices extracted from the literature and broken down into specific activities. For data analysis, the maturity model employs a hierarchical calculation procedure that incorporates fuzzy logic to cope with subjectivity in the assessments. The proposal was empirically validated through three case studies in Brazilian industrial companies from different sectors and at different stages of maturity. The results demonstrate the model's potential to support the organizational transition towards circularity, providing a diagnosis that highlights the most advanced practices and priorities for improvement.
