An increase of the waste plastics is one of the major problem in respect of environmental issue and the resource recycling. Therefore, a new regulation such as Containers and Packaging Recycling Law was enforced to promote the recycling of the waste plastics in 2000. It is necessary to promote recycling, though the amount of the waste plastics in 2001 reaches around 10 million tons, and the recycling rate increased to about 53%. This paper is a review of the use of waste plastics as a substitute reducing agent for coke and pulverized coal in blast furnaces. In blast furnace, waste plastics can be used with high efficiency thanks to the function of combustion and gasification of blast furnace. It is considered that waste plastics injection into the blast furnace is a favorable way to realize feedstock recycling of waste plastics and to solve environmental issue.
