In recent years biofuels have obtained a considerable interest, due to the implementation of ruling and gradual replacement of fossil fuels. One of production steps at gaining the oil is a pressing process. Wastes come into being from this process. These wastes are used as feed, fertilizer prospectively as fuel. A contemporary scientific literature pays attention namely to one of prospective produces which is a produce of the tropical and subtropical zones Jatropa curcas. Tests were performed at Jatropha Curcas seeds of a brown colour (that means gnaw). The aim of a research is an analysis of Jatropa curcas seed from the utilization point of view of the gross calorific value. The basic instrument to evaluate the gross calorific value of each variant of the experiment was a calorimeter PARR 6200 and digital scales for accurate laboratory weighing.
