# Top 30 environmental services companies in the Seine-Saint-Denis department
Tamtam tracks 34 environmental services companies headquartered in the Seine-Saint-Denis department. This list ranks the 30 largest by number of employees on LinkedIn, led by Veolia, Veolia | Water Tech and Veolia | France. Their median headcount is 98. Half of them were founded in 1995 or later. The most common headquarters are Aubervilliers (9), Saint-Denis (4) and Montreuil (3).
The environmental services sector in Seine-Saint-Denis is largely dominated by several entities of Veolia, a major group in water, waste, and energy solutions. These include Veolia, which builds environmental security and regenerates resources; Veolia Water Tech, offering global water technology expertise; and Veolia France, specializing in water management and waste treatment. Other notable companies include BWT France, a water treatment solutions provider, and Groupe Chimirec, which manages hazardous and non-hazardous waste. Emma眉s France, a civic organization, also contributes to a circular economy.
Most of these companies are well-established, with a significant number having been founded before 2000, such as Veolia (1853) and Groupe Chimirec (1958). A clear pattern is the concentration of headquarters in Aubervilliers, home to many Veolia divisions, alongside other key locations like Saint-Denis and Montreuil. The presence of government administration bodies like Plaine Commune and La CINOR further highlights the region's focus on urban and environmental management.

## 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 12, 2026.
