Tamtam tracks 100 environmental services companies headquartered in Grand Est. This list ranks the 50 largest by number of employees on LinkedIn, led by Ginger, Groupe NICOLLIN and SIAAP. Their median headcount is 147. Half of them were founded in 1975 or later. The most common headquarters are Metz (2) and Troyes (2).

The environmental services companies in Grand Est include both established public administrations and private firms. Among them are major players like Groupe NICOLLIN, which handles waste management and urban sanitation, and SIAAP, a public company providing wastewater treatment for the Paris metropolitan area. SIS specializes in sanitation services within the Grand Est region, while Syndicat des Eaux et de l’Assainissement Alsace-Moselle focuses on water supply and sanitation for numerous municipalities.

Several large government administrations such as Communauté urbaine du Grand Reims and Eurométropole de Metz are also present, indicating a strong public sector involvement in environmental management. A notable pattern is the presence of companies with a long history, such as Groupe Brangeon, founded in 1919, and Ginger, established in 1933, suggesting a mature industry with deep roots in the region.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
