What Sanexen does

Sanexen Environmental Services Inc. is a Quebec-based environmental solutions provider founded in 1985 and operating as a wholly-owned subsidiary of LOGISTEC Corporation. It delivers specialized environmental services and water treatment solutions to industrial, municipal, governmental, and Indigenous clients across Canada, the United States, and increasingly Europe. The company operates through two main service lines — Water Solutions (biosolids management, dredging and dewatering, industrial effluent treatment, and PFAS removal) and Specialized Environmental Services (site remediation, degraded site valorization, regulated materials management, risk assessment, and soil/material management) — and through its American Process Group (APG) division for U.S. and Western Canada dredging and biosolids work.

The technology stack centers on three proprietary platforms: the ALTRA PFAS Solution, a foam-fractionation-based continuous treatment system with mobile modular units; ULTRASORPTION filtration for dissolved and colloidal contaminants; and a patented C&D Fines Recovery Process operating at North America's first such facility with up to 150,000 metric tons per year of capacity. Revenue is generated through project-based and long-term managed-service contracts (including a 10-year PFAS contract with Waste Connections), with customers spanning Quebec MELCCFP, City of Iqaluit, PJCCI, Ville de Boucherville, Couchiching and Tlicho First Nations, and the Albuquerque Bernalillo County Water Utility Authority. Distribution is direct enterprise field sales, supported by three Indigenous joint ventures (Qikiqtaaluk Environmental, Avataani, Naàka Environmental), the APG division, and a 2025 strategic partnership with France's DI Environnement for European PFAS expansion.

The business model is services-driven rather than software-driven, with pricing delivered through tailored project bids and long-term operating contracts rather than standardized tiers. Notable scale signals include over 6,000 projects completed, over $2 billion in cumulative environmental works, over 10.3 billion litres of contaminated water treated, and 19 million tonnes of impacted soil managed. Operational milestones include the 2020 C&D plant opening, the 2021 APG acquisition, the 2023 Waste Connections PFAS award, the December 2024 appointment of Nathalie Viens as President, and the March 2026 opening of a new Québec City office.
