Stablex is one of North America's largest and best-known providers of services for the treatment and disposal of hazardous waste. Using technology that is recognized worldwide, they provide industry with scientifically sound and environmentally secure waste management solutions. Hazardous waste contains toxic substances that can adversely affect the environment - and alternative disposal methods have limitations. Incineration is costly, and results in large volumes of exhaust gases and potentially toxic ash. Direct placement of untreated waste, even in secure landfills, is not a fail-safe solution. Recycling, invariably the preferred course is not always feasible, given the make-up of industrial residues. How then can communities be protected from environmental degradation? In many cases, only by applying the Stablex treatment process. Using a unique technology, Stablex characterizes, treats and stabilizes inorganic industrial wastes and contaminated soil before disposing of the benign product in a dedicated secure placement cell. The company is committed in maintaining their track record of environmental excellence and superior management practices to ensure, Stablex provides the most effective and reliable service for their customers. Stablex commits to the ethic of Responsible Care. Responsible Care is a global effort aimed at addressing public concerns about the impact of chemicals on health, environmental and social issues. It is designed to guide companies to dedicate themselves, their technology and their business practices to sustainability - the ongoing betterment of society, the environment, and the economy.
