# List of environmental services companies in Normandy

Tamtam tracks 45 environmental services companies headquartered in Normandy. This list ranks all of them by number of employees on LinkedIn, led by Métropole Rouen Normandie, Groupe LHOTELLIER and Le Havre Seine Métropole. Their median headcount is 47. Half of them were founded in 2012 or later. The most common headquarters are Le Havre (3).

This selection of the largest environmental services companies in Normandy primarily features public sector entities. Organizations like Métropole Rouen Normandie and Le Havre Seine Métropole manage vast municipal services, including water, waste, and transport, while also driving local development and environmental initiatives. LABÉO specializes in high-tech analyses for animal health, water, and food products, contributing to public health and environmental oversight. Handiprint, an inclusive company, offers printing services with environmental initiatives.

A significant pattern among these companies is their focus on public administration and inter-communal cooperation, with many organizations like Communauté d'agglomération du Cotentin and Évreux Portes de Normandie established in the mid-2010s. This indicates a recent trend towards consolidating regional services and environmental management in Normandy. STGS - Groupe STURNO supports local authorities in water and sanitation services across western France.

## 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.
