The Treatment Process

Incineration Process


In these units, combustion operations are carried out in two separate chambers. The primary chamber accepts the waste, and the combustion process is begun. Three processes occur in the primary chamber. First, the moisture in the waste is evaporated. Second, the volatile fraction of the waste is volatilized, and the volatilized gases are directed to the secondary chamber. Third, the nonvolatile combustible portion (fixed carbon) of the waste is burned. The typical operating temperature range for primary chambers is 700°C to 800°C. Combustion gases containing the volatile combustible materials from the primary chamber are directed to the secondary chamber. Here the gases are burned with excess air, and at least one auxiliary fuel burner is used, as necessary, to maintain temperatures. Typical operating temperatures for secondary chambers range from 900°C to 1100°C with 2 seconds residence time of gas Combustion gases from the secondary chamber are then vented through the stack to the atmosphere with the good control and technology on combustion, Therefore vent gas is clean meeting all the strict environmental regulatory guideline thereshold limits on air pollutants.


Medical waste incineration is the process of burning specific wastes, including pathological, trace chemotherapy and non-hazardous pharmaceutical wastes as it is considered the safest, most effective means of treatment and prevents harm to the environment and our health in general. There are alternatives to incineration including autoclaving, chemical treatments, or ozone disinfection, but these technologies are admittedly incapable of completely destroying certain medical wastes, such as pharmaceuticals and specific pathological wastes. These facilities can be also used to burn dead animals, cigarettes, chemical wastes, other hazardous wastes and much more. With advancements in medical treatment technologies and increases in regulations for proper waste management the amount of medical waste resulting from healthcare is expected to increase. Medical waste and the need for incineration is an outcome of the advanced healthcare system from which we all benefit. Stericycle provides a valuable and necessary behind-the-scenes service that protects our communities from harmful pathogens and chemicals, thereby supporting the continuity and reliability of healthcare into the future.
