A new complex plant for carbonization and composting of municipal wastes proposed for Gero City is introduced.The separated combustible waste and non-separated combustible waste are carbonized in two fluidized carbonization furnaces in the plant,and the coke produced is used in steelworks.The separated garbage and forest-wastes are mixed with dried septic-tank sludge to produce high quality compost for farms.This use of waste materials in the complex plant considerably lowers the amount of waste going to land-fills,and in addition,creates lower total emission of dioxins and carbon dioxide into the environment.
