Séché Environnement, an innovative player in waste management, continues to develop its activities in support of the circular economy, decarbonization, and environmental protection. In a complex macroeconomic and geopolitical context, the Group supports its clients throughout their transformation processes, contributing to the preservation of resources, climate, and biodiversity, while continuing to create value.
Amid the ecological transition, the waste management sector faces major challenges such as hazardous waste control, reducing the volume of final waste, and developing recovery solutions. In this context, Séché Environnement promotes recycling, material recovery, and local energy production.
In 2025, the Group reaffirmed the strength of its positioning, delivering solid results both in France and internationally, despite a temporary slowdown in certain activities. This evolution does not call into question its fundamentals or the achievement of its extra-financial objectives, particularly regarding its alignment with the European green taxonomy, as well as its climate and circular economy targets.
The Group’s activities are built around key priorities: health and safety, high value-added solutions, water management, risk control, and biodiversity protection. These commitments are reflected, in particular, through its ability to respond to environmental emergencies and through the development of advanced technologies, especially for PFAS treatment.
Growth also expanded into promising markets, driven by strategic acquisitions such as Hidronor in Chile and La Filippa in Italy at the beginning of 2026. The Group further strengthened its position in sustainable finance through the successful issuance of green and hybrid bonds.
Supported by its business model, the commitment of its teams, and its innovative spirit, Séché Environnement reaffirms its determination to contribute sustainably to both environmental and social transitions.

Beyond the stated commitments, it is imperative that our activities are carried out in accordance with national and international laws with which we are strictly required to comply.
