Logotipo Águas Negras

The original logo was developed by Hermann H. Purnhagen, who originally developed it in 1951 for the company Lidar, a manufacturer of steamers for wood. In 1976 the logo was adopted by the company Águas Negras.


Over the years, several restyling were carried out and, in 2020, the image was restyled based on the original, by Gerold R. Purnhagen together with his son-in-law Malcolm Macdonald.


Some colors changed as well as a slight adjustment of the positioning of some details of the image and, new in 2020, the removal of two circles to make the logo lighter and more approachable.


From November 2020 the logo of Águas Negras SA Indústria de Papel is contained in a perfect white circle, with the expression ÁGUAS NEGRAS S.A. at the top and INDÚSTRIA DE PAPEL at the bottom in dark green.


The expressions are separated on both sides by nine curved black lines


In the center of the logo, there is a stylized image of a brown cinnamon tree. The tree culminates in five peaks, all crowned by three ovals representing Araucaria pine cones, symbolizing fertility. These ovals are dark green in color.


The logo conveys the idea of a modern and environmentally friendly company with an important recognition and honor of its history and a confident gaze into the future.
