In 1967, after several successful years of working for Mercedes Benz in Stuttgart, Germany, Josef Dagn returned back to his rural home town of Koessen, Austria, where he rented a small garage. In 1970 he started a radiator repair service for both modern and vintage cars. In 1980 he developed the first SEDA plug, which has now been sold over 200.000 times. In the same year he also presented a complete radiator testing system at the Automechanika trade fair in Frankfurt, German

After expanding the garage Mr. Dagn concentrated on developing devices and specialty tools for cars of reputable enterprises such as Mercedes Benz, Vauxhall, VW, Renault, General Motors, Volvo, Peugeot, Nissan, Ford, Seat, MAN and the German automobile club ADAC. In 1984 SEDA expanded again when SEDA of America was grounded in New York. In 1991, after the development of a SEDA built Sports car, the AC cobra replica which won many awards. It was at this time that Josef Dagn built the first coolant recycling machine. By the end of 1993 the development of the world’s first complete vehicle drainage system was complete.

SEDA began their research and development department which continued to refine existing products as well producing innovative new ones. The SEDA products were very well received in the USA. In 1999 SEDA America was changed to SEDA Environmental Inc and the headquarters was moved to St. Petersburgh in Florida. 2001 was the year that SEDA Environmental Days first took place. A platform where customers, the automotive and recycling industry meet to, discuss new Ideas, standards and products. In 2003 SEDA changed to SEDA-Umwelttechnik GmbH. Due to great success in the Netherlands, SEDA Environmental Benelux B.V. was founded. SEDA successfully installed and still maintains 250 SEDA Systems in the Netherlands.
