This article describes the circular economy model proposed for Santiago de Cali, which is mainly oriented to the analysis and efficient use of construction materials, taking into account the recovery of ecosystems and the circular flow of stony materials. This useful tool for the business sector, government and civil society, includes the analysis of the production of construction materials, construction process, use and operation, and completion of the life cycle of buildings and infrastructure. In particular, the model proposes specific strategies for the use of Construction and Demolition Waste (C&DW ) supported on applied research (case studies). In addition, this model includes the C&DW management system and some characteristics of the Environmental and Technological Park, the main proposal for valorization of the C&DW.
