The intensification of tire consumption, driven by the expansion of the Brazilian vehicle fleet, has exacerbated the challenges related to solid waste management, particularly in urban microregions. Among such waste, end-of-life tires represent an environmentally persistent liability due to their durability, complex composition, and volumetric impact. This study aims to analyze the environmental and economic implications of end-of-life tire management in the Cascavel microregion (PR), emphasizing the potential of circular economy practices. The research follows a descriptive and quantitative approach, grounded in bibliographic review and the analysis of secondary data obtained from official public sources. The investigation comprises the mapping of the tire life cycle, identification of recovery methods, and assessment of current recycling and co-processing technologies. It also includes the examination of the legal framework established by the National Solid Waste Policy, with a focus on reverse logistics mechanisms and destination credit systems. The findings suggest that the implementation of circular strategies, combined with technological innovation and strengthened public policies, may reduce the environmental burdens of improper disposal, alleviate pressure on landfills, and foster the development of new value-added production chains. The study concludes that the Cascavel microregion has the structural conditions to become a regional benchmark in sustainable waste management, provided that public authorities, private actors, and civil society adopt a coordinated and integrated approach.
