The headquarters of Otto Graf GmbH are at the Teningen site. Distribution activities in the relevant countries are coordinated from here.

To ensure continued sustainable growth in the future, around €20 million euros are being invested at the Teningen site to expand production and logistics. One of the most up-to-date production plants for plastic products anywhere in the world is being erected here on an area of 155,000 m² – this corresponds to 31 football fields. A new type of production process will be used in the new works, which have a building area of 13,500 m² and a height of up to 15 metres. Various new products will be the main output of the new works, e.g. a new range of tanks for rainwater harvesting.

Rotation production takes place in Dachstein. Tanks with a volume of up to 9,200 l are produced here. The injection moulding department with six large machines up to 4,000 t produces rain butts, composters and accessories for rainwater harvesting. For a long time the site at Dachstein was the larger of the two GRAF sites. Today, with a total area of 90,000 square metres, it is approximately the same size as the Teningen site.
