History History The SETA Group had its origin in 1941, with the founding of Sociedade Extrativa Tanino de Acácia (whose initials gave rise to the name SETA) in the town of Estancia Velha. The company was the first black wattle tannin industry in the American continent and it was formed by tanners, led by Mr. Edvino Leuck.

SETA emerged to meet the demand of acacia tannin by local tanneries and later to meet the needs of the entire national market. In times of world war, facing all the adversities from this situation, the entrepreneurs started the first plant with used equipment, due to the inability to rely on the local industry and for not being able to import equipment and products. Thanks to the great efforts of its managers and the quality of its products, the company quickly started to operate in the international market. Production which started with 500 kg / day, reached in five years 5 tons / day of liquid and solid acacia tannins.

As business developed, a new branch was founded in May 1946 in the city of Taquari (RS). The geographical location of the branch represented an opportunity for future growth due to direct access to the port of Porto Alegre, where all the production from Rio Grande do Sul state was shipped. At the same time, it adopted the name of S.A. Extractiva Tanino de Acácia and Mr. Edvino Leuck lead the business.

During the 50’s, other competing companies opened in the sector in Brazil, healthy indeed for the development of the market. Quickly the domestic production of acacia tannin met the domestic demand.

The modernization of production processes accentuated during the 70’s, with the adjustment of the industrial plants of Taquari and Estancia Velha for powder acacia tannin production and also granulated and atomized. At that time, the person in front of the business was Mr. Mario Leuck, son of Mr. Edvino Leuck. The company had a production of 30,000 ton / year of acacia tannin, still sufficient to meet the leather market.

In 1987 a subsidiary dedicated to the development, production and marketing of derived chemicals from tannin and petrochemicals was created. The company now grew to other segments of the chemical industry.

In 1996, Mr. Carlos Alfredo Leuck, third generation of the Leuck family, took charge of the business. Besides acting strongly in the reengineering business, professionalizing the management of the companies, the grandson of Edvino Leuck accelerated the internationalization of business, diversifying markets for products derived from Acacia tannins. He also began the export business of black wattle wood through the creation in 1999 of a joint venture with the Japanese company Mitsubishi Corporation, named MITA Ltda, located in the town of Taquari, next to the SETA plant. Thus, in addition to expanding the acacia wood market, he also added value to the entire supply chain, stimulating the producer and encouraging the cultivation of the species.

In 1999, Acquaquímica Ltda was also established. This company focused on providing derivatives from acacia tannin products for other industries, such as: sugar, alcohol, oil well drilling and also for treatment of drinking water and wastewater, among others.

In order to strengthen the competitiveness of the companies within the Group and meet the growing demand of the global market, we initiated the SETA Quality Program, culminating in the ISO 9001 certification in June 1999 for tannin and in 2002 for specialty chemicals. In 2003 we also obtained the ISO 9001 certification on the tannin-based specialty chemicals manufactured by Acquaquímica Ltda.

With our goal to adopt sustainable practices, in 2004 MITA Ltd. was certified by the international FSC (Forest Stewardship Council). This certification follows strict environmental, social and economic criteria, which allows a sustainable development of products through the adoption of environmentally sound practices, socially just and economically viable.

In September 2008, the production of specialty chemicals was transferred to the main plant. In November 2009, the activities of the SETA Taquari closed, and from this moment on the company invested in the expansion and modernization of the production process in Estancia Velha, which concentrated all the tannin production of the SETA Group. With these changes, the Group has gained in productivity and quality of its processes, enabling better service to customer and market needs.

In 2009, SETA acquires from their Japanese partners their participation of MITA, which led to the construction of its branch in Rio Grande and later the wood chips production operations in 2013. The new plant began using raw materials originating from the forests of the southern half of the state, stimulating the economy in addition to expanding business possibilities.

The current management of the Group, led by the fourth generation of the Leuck family, aims to seek market expansion and diversification into new businesses. With offices in Europe and Asia, with representatives and distributors in over 70 countries, the SETA Group, which in 2016 celebrated its 75th anniversary, maintains the commitment to continue investing in the development of our state and the appreciation of the acaciculture.
