Cobogó and sustainability: design and innovation based on waste recycling

This paper aims to highlight the sustainable character of the "cobogó" hollow element, addressing design elements and production methods that involve waste recycling processes. Created in Brazil in 1929, cobogó has the basic function of promoting the sealing of private spaces, whilst allowing the passage of light and constant natural ventilation. Initially, the artifact was made of cement and ceramics. However, over the decades, there has been greater diversification in terms of the materials used in its composition. With the technological increase in production innovations, the appreciation of the concept of sustainability has led to creative ideas for the use of waste in the production of cobogós flourishing in recent years. Therefore, in this work, six experiences are presented that materialize these initiatives, idealized by design professionals or university students, thus evaluating the developments for the construction market and the respective social and environmental benefits promoted.
