In order to prevent the spreading infectious disease in domestic animal, livestock excretion should be controlled bysterilization. The basic concept of sterilization can be described by thermal treatment under vacuum state. From the basicconcept of sterilization, livestock excretion can be converted to produce renewable energy using the method ofcarbonization and the method of carbonization can also be reduced greenhouse gas effectively. Chicken manure is usedas a sample of renewable energy source in the carbonization reactor. The basic energy characteristics of chicken manuresuch as proximate analysis, and heating value are estimated. The carbonization residue of chicken manure which isobtained from carbonization experiment is subject to several analyses in order to examine the energy characteristics suchas heating value, fuel ratio, combustible index and yield. As increased carbonization temperature, both heating value andfuel ratio (fixed carbon/volatile combustible) of the residue are increased up to 350oC but yield of the residue is decreased.From the results of bulk density, fuel ratio and total heating value of the residue, the optimal conditions of carbonizationtemperature and time can be decided by about 350oC and 15min. Since the residue of chicken manure can not be satisfiedwith the standard of the third grade of solid fuel product, it is desirable that chicken manure be modified with othermaterials to improve an energy potential and to use as a clean fuel.
