n a country like Brazil, where vital segments such as science and sustainable development have little visibility, sustainable science has gained a new ally: The STAC Organization. A public school alumni initiative born of a dream and an inspiring project. The name of the organization is a tribute to the award-winning, internationally recognized project of founders Beatriz Ruscetto, Gabriel Trindade and Matheus Henrique: STAC-IBR (Tank Installed Water Treatment System in Brazil), which as well as the values of the organization , aims to make science compatible with sustainable development, encourage national research and, above all, produce a positive impact on society. We hope that the history of STAC directly inspires the path of many students to the realization of their dreams, as it inspires us daily.
