Flue Gas Treatment. Incinerating waste produces exhaust gases laden with diverse pollutants. Different processes are used to remove these pollutants before the purified flue gas leaves the plant safely through the stack. For decades HZI has been doing research into flue gas treatment and developing new and effective treatment systems.
