Safe disposal of hazardous waste has become a priority focus over the past 30 years. In order to help better preserve the environment, these wastes need to be disposed of safely to avoid dangerous heavy metals leaching back into the ecosystem.

Your challenges
When it comes to disposing of hazardous waste, many protocols need to be followed. In the 1970s and 1980s, a growing focus on the environment and improving environmental laws in Canada and the United States forced many treatment and disposal options for hazardous waste to evolve. Having the capital and manpower to keep up with these disposal techniques is often something that most municipalities do not have access to.
Our solutions

SUEZ views the environment, health and safety as a top priority. Through our more than 40 hazardous waste facilities operated worldwide, we have developed a complete specialized process line to safely treat and dispose of hazardous waste.

 

 Reception: Waste arrives by means of trailer trucks. Verifications, labeling and regulatory paperwork ensure tracking of the disposal process.
• Inspection and Pre-Treatment: The waste is inspected, analyzed in laboratory and/or pre-treated (shredded, mixed, resized) before going through the main processes.
• Incineration: Organic wastes are destroyed in the incinerator at temperatures above 1922°F. This achieves a Destructive Removal Efficiency of at least 99.9999% of hazardous organic compounds.
• Neutralization: Inorganic liquids are chemically and physically rendered non-hazardous in the “Phys-Chem” process, utilizing a combination of acid/base and redox properties.
• Stabilization: Fly ash is mixed with cement, which constitutes one of the many barriers against leaching of trace amounts of heavy metals.
• Post-Treatment: Flue gas scrubbing removes acids and particulates while effluents are cleaned using wastewater treatment techniques.
• Landfill: Stabilized material is disposed in the on-site Class 1 landfill. Cells are secured with clay, geomembrane and are re-vegetated.
• Deep Well: Treated liquid effluents are injected into a deep well roughly 6,000 feet below the surface into a stable geological formation.
• Environmental Monitoring: Any potential impact of the activities on the environment is closely monitored. Surrounding wildlife, air emissions, surface and ground waters, landfill and deep well integrities are constantly studied in order to verify that the prime goal of the facility is achieved: protect the environment.
