Comet Group’s roots date back to 1986, when Alfred Grosjean took over the Paridans sites in Aubange, followed by the Bodson yard in Châtelet in 1987.

The tonnages processed by the company quickly increased and it started to expand its operations.
Compagnie des Métaux de la Sambre (now Cometsambre) was set up in 1988, followed by Recymet four years later, marking the beginnings of Comet Group.
That year, Alfred Grosjean’s son, Pierre Grosjean, took over the management of the company, after spending several years working out in the field and gaining extensive industry experience.

He continued to develop the Group’s activities over a 5-year period until his brother, Philippe Grosjean, took the helm in 1997.
Comet Group quickly consolidated its position and sought to expand and develop its activities.
By taking over existing companies and setting up new ones, the Group consolidated its position on the ferrous and non-ferrous metals market and also extended its expertise to other recycling-related fields.

Today, Comet Group holds around thirty companies across Belgium and France and has a range of outstanding facilities that have enabled it to achieve unrivalled recycling rates.
