This article shows teaching, research and extension actions focusing on the use of materioteca. The main objective is to promote the dissemination of sustainability knowledge in projects, taking as a starting point the material selection process. This article presents a materioteca with a new concept, where in addition to samples of materials and technical information, it presents a complete report on the economic, social and environmental sustainability of each material (ESA). Complementary extension actions include the development of comics, videos, models and prototypes. The initial results of the present research demonstrated that it is possible to provide designers with an analysis of the relative sustainability of each material compared to similar ones, providing a very relevant set of design information.
