Umuarama, in the northwest of Paraná, was founded on 26 June 1955 and completed 70 years in 2025. Despite its historical youth, it has consolidated itself as a regional center of development, with an economy based on agribusiness, commerce and services. Recognized as the "Capital of Friendship", it stands out for its modern infrastructure, good health, education, leisure and safety indicators, as well as quality of life for its inhabitants. Its cultural identity and strategic position in the Entre Rios region reinforce its attractiveness as a promising medium-sized city in southern Brazil. The study evaluates the urban development of Umuarama in relation to the Sustainable Development Goals (SDGs), identifying advances and challenges. The circular city approach involves not only environmental and economic aspects, but also social inclusion, job creation in the circular economy, and community empowerment through sustainable public spaces. According to the Sustainable Development Index of Cities (IDSC-BR), Umuarama occupies the 325th position in the national ranking. Although it is not among the most sustainable, it already has practices aligned with the SDGs: health and leisure services (SDG 3), structured educational institutions (SDG 4), diversified economy that promotes decent work and growth (SDG 8) and green areas that support sustainable cities (SDG 11). The performance in the IDSC-BR indicates advances in quality of life, infrastructure and economy, but also reveals challenges in waste management, use of renewable energy and urban mobility. The municipality has favorable conditions and alignment with the SDGs, but needs to expand environmental policies to consolidate itself as a reference in sustainability.
