In the 1820s, Saint-Etienne area was one of France’s main coal mining sites (more than 200 mine shafts in the region). This mining industry stimulated creativity and enhanced the attractiveness of the region. Thus it was that the first railway track on the European continent came into being between Saint-Etienne and Andrézieux-Bouthéon.

When BONY was founded, coal production in the Loire district amounted to roughly 2 million tonnes. It was to grow continuously over the next few years, thus encouraging the installation and development of foundries, steel mills and forges.

BONY thus started up its activity in close proximity to its customers and suppliers.
