At present, the circular economy approach is manifested in the supply chain as a closed cycle, where waste from some productions is used to elaborate new derivatives. In this context, the diagnosis of the Ecuadorian shirt supply chain is developed and the possible uses of the waste are identified. A checklist is used for the evaluation of integration, descriptive statistics (Fashion) and inferential statistics (Correlations, contingency). The results of this research are: the low level of integration of the chain under study with a value of 1.4; where the variables of greatest weakness are: strategy, information, purchases and inventory. This work presents a practical value, because it is used to improve the actors of the textile industry in that country.
