This study describes properties of biomasses of Moringa oleifera Lamarck for energetic applications of production of biodiesel and briquettes. The seeds collected of the mature pods were the initial biomasses used of this plant. The seeds were separated into husks and oilseed grains, from which the oils were extracted by mechanical pressing and by solvent extraction. The crude oil mixed (of pressing and by solvent) was degummed, neutralized, washed, dried and characterized. The purified oil was

The residual peels and pies had their calorific powers measured and compared with classic agricultural residues: firewood, sugarcane bagasse and coconut husks. Moringa culture was compared to soybeans in agricultural and biodiesel production perspectives. The analytical results show that the biomasses of the moringa are favorable as renewable biofuels like biodiesel or briquettes due to the good calorific power and simple and accessible productive technology. The production of briquettes starting from the biomasses of the moringa would be recommended with the uses of the pod husks, seed peels and pies (cakes) of extraction of the oil. The agricultural management and the simple productive technologies applied to the moringa are favorable for social inclusion by enabling family agriculture.
