OPEN ACCESS
In this study, several experiments were performed to decrease volume or weight and detoxification of solid organic wastes produced from various agricultural activities and industries in Japan using the pyrolyzing and/ or carbonizing process. Additionally, these solid organic wastes were also transformed into the stable materials of char (so-called ‘pyrolyzed waste char’). The objective of this study was to develop an effective utilization system of the waste char pyrolyzed and carbonized from the solid industrial organic wastes using the pyrolysis equipment with overheated steam or fluidized bed pyrolysis equipment. From the feasibility study, it was sug-gested that waste char-biomass briquettes that are produced from the pyrolyzed waste chars of waste tires, cow manure and poultry manure are used instead of the fossil solid fuel (e.g. coal) based on their burning character-istics and analytical results of exhaust gases.
