To combine a steel industry or the like whose control of a carbon dioxide yield is necessary, and which is a large amount of energy use industry with a woody biomass feeding ground which commands a view of promoting felling than present to keep a carbon dioxide absorption capacity of a tree high, and to enable to make measures for controlling global warming efficiently as the entire Japan.
Woody biomass is made wood chips in an accumulation ground so that the mean diameter may become at least 1 cm and at most 10 cm, and is heat-treated so that a surface layer of the wood chip may become at least 350°C and at most 450°C, then the wood chips are transported to a use location, and ground to be used by a high temperature. When the use place is a pig iron making process of ironworks, the wood chips are blown into a blast furnace in powder or are made coke with coal to be charged into a blast furnace. Moreover, in a steelmaking process woody biomass's particulates are blown into a hot gas generated while blowing a steel making converter. Particulates which are separated and collected from an exhaust gas of a steel making converter are molded in a state containing carbon and are heat-treated by a to be used effectively.
