JFE Engineering Corp. has provided ten facilities of high temperature gasifying and direct melting plant in Japan. These plants are able to treat various kinds of waste, such as municipal solid waste(MSW), industrial waste, ash, refuse derived fuel(RDF), asbestos, etc. Recently, a social demand of reducing the coke consumption is becoming larger. In this situation, JFE Engineering Corp. has studied various methods of reducing the coke consumption. In this paper, we show test results of application of Bio-coke as an alternative energy resource. However Bio-coke contains more than 70wt% of volatile matter, coke can be substituted by Bio-coke having some calorific value. In this study, the cut-down ratio exceeded 50%. This shows possibility of remarkable decrease in CO2 emission.
