Our history

1985-1996: pioneering for the environment

Our journey began in 1985 in Mayenne, northwest France, when Joël Séché took over his family's small public works business.

Having quickly recognized the need for a paradigm shift in waste management, he developed the company's first waste storage facility in Changé, northwest France. The site was the first in France to meet modern standards. It was designed to protect the environment from the impact of waste and to harmoniously blend in with the surrounding area. From the very beginning, to goal of preserving biodiversity lay at the heart of the Séché project.

1985 - 1st landfill for non-hazardous waste

Joël Séché created Laval Services, 1st entity of the future Séché Environnement group, based on the family public works SME he had just taken over. The mayor of Laval asked him to develop the most effective solution for the town’s landfill site. After having studied best practices from around the world, he opened the first non-hazardous waste storage facility (class 2).
