This project aims to implement a socio-environmental enterprise called Textile Waste Bank, BRT, aimed at the revaluation of textile waste within selective collection cooperatives in the city of Londrina, state of Paraná, Brazil. The research method used was Action Design Research, complemented by the use of Unsystematic Bibliographic Review (UBR). Among the theoretical and methodological concepts guiding this work are Systems Thinking, Systems Design, Business Model Design, Design Thinking, and Design for Sustainability, Distributed Economies, and Circular Economy. It was developed in an interdisciplinary way, with the support of researchers from the areas of management and engineering, and involved the development and implementation of an artifact, in the form of a system for the collection, sorting, processing, and commercialization of post-consumer textile waste. The learning obtained in this development was the basis for the creation of the aforementioned implementation model, providing both the production of knowledge and a social change in the reality of the workers of the cooperative that is the subject of the study.
