The central theme of the symposium is Sustainable Urban Development, exploring how cities can grow and evolve resiliently, with companies working intelligently and ecologically toward a better future. The focus is on collaborative solutions driven by the private sector . The emphasis is not individual corporate actions, but rather on the synergy and interdependence among key sectors such as sanitation, construction materials, and energy, as a driving force for urban transformation. The event will take the form of a panel discussion, featuring individual presentations by representatives from the three companies, followed by a joint debate to deepen the dialogue on how their solutions intersect are integrated with one aother. Adopting an integrated and systemic approach, the symposium connects three fundamental pillars of urban sustainability: Infrastructure and Maintenance (BRK), Construction and Housing (Flora), and Energy (Origem Energia). Together, they will illustrate—through real-world examples—how cross-sector collaboration contributes to building sustainable and resilient urban ecosystems.
