 The material obtained from cow manure is rich in carbon and has good heat capacity. Its characteristic feature is its predominantly cellulose composition. Research shows that the carbon contained in manure makes it usable as fuel. The use of bio-carbon materials, which have valuable features in terms of renewable and rich resources to replace fossil materials, is important in the metallurgical industry. In this study, the functional group containing carbon and the thermal carbon, hydrogen and nitrogen values of cow manure dry at 105 °C (QD105) and pyrolyzed cow manure dry and at 350 °C (QD350) were investigated using FTIR and CHNS analysis. The study shows that the product of slow pyrolysis (10°C/min) up to 350°C of dry cow manure powder has C, H and N values of equivalent carbon content of 29.77, 2.45 and 2.11%, respectively. Reactions and thermal decomposition of cow manure reduce the CO 2 gas present in its charcoal. The highest heating value (HHV) is 19.82 kJ/Kg. Cow dung charcoal creates different properties in terms of temperature, storage time, heating rate and efficiency. At a temperature of 325–500 °C, CO and CH 4 gases have the highest efficiency.
