The headquarters of the company Zeolite Petrota Industrial and Commercial S. A. “O Lithoxoos” (The Mason) is the village of Petrota, which is located in the Northeasternmost area of Greece, in the municipality of Orestiada in the regional unit of Evros.

Petrota, a village with a very long history throughout the centuries and a long cultural tradition, was one of the most dynamic villages of the region, both from an economical and a demographic aspect, until the middle of the twentieth century, as it was the largest village in the area with about 2,000 residents.

The company was founded with the initiative of both village residents and of former residents who have migrated to other areas of Greece or who have immigrated (mostly to Germany). Having understood the importance of the ore, they wanted to capitalize it in its mining location and avoid its transportation and processing away from the region, as their vision has been the economical, social, and cultural rebirth of their homevillage and the larger area.
