Coke is essential for the operation of a Blast Furnace. However, in recent years new coking plants have not been built, which have caused the ageing of the existing infrastructures for blast furnace coke production. So, the challenge which coking industry in the new millennium has to face up is the modernization of the old coke production structures. In relation to alternative coking systems, in the European Union the Jumbo reactor or "Single Chamber System" (SCS) has been developed, whereas in USA non-recovery ovens based on the primitive beehive ovens are used. In Japan the project SCOPE 21 is being developed.
