In 1938 Mr. Leopoldo Jorge Theodoro Schmalz began his dream of producing yarns and threads for handicrafts. Today Círculo is one of the largest textile industries in Brazil.

Circulo is engaged in making its products more sustainable. In order to do so Circulo uses new technologies that provide minimum emission of pollutants for product creation. One of the new technologies implemented is the Dye Clean technique which allows the water of the same bath to be used for various dyeing without the need to be fully exchanged, which generates a savings of 90.92% of water.
