This paper describes an attempt to analyze the usability of Jatropha curcas L. seed cake as a future ecological solid fuel. Jatropha is a unique and potential tropical plant and it is propagated for augmenting renewable energy sources due to its several ecological and environmental benefits. The plants are cultivated in extensive plantations on degraded wasteland throughout the world. The analysis of Jatropha seed cake comprised the following aspects: analysis of possible utilization of Jatropha cake as a substitution for standard woody pellets in domestic boilers, assessing of the physical and chemical properties. Analysis of possible utilization of Jatropha seed cake as a raw material for production of briquettes, assessing of the physical and chemical properties of briquettes, analysis of emissions and comparison with standard woody pellets. The performed physical and chemical examination of the Jatropha seed cake gives the opportunity to make a conclusion, that it, in comparison to standard woody pellets, reaches similar or better physical and chemical properties, it is also able to reach the European standard EN 14961-1 for solid biofuels.
