In a country of vast land area and a large agricultural potential such as Brazil, one of the biggest challenges is to develop arrays of energy from alternative sources of low cost, making them economically competitive. In this situation, several research institutions of the country have struggled to develop new alternatives, and among the various possibilities, we highlight the use of biomass residues for power generation by burning. The Terminalia catappa L. popularly known as walnut is a species adapted to all regions of Brazil, which make it a viable source of biomass. In this study, we evaluated the quality of some parts of the nut for energy purposes. The samples were crushed immediately after being collected and were made the following physico-chemical characterizations: gross calorific value, ash content, moisture and density. The calorific value observed for the species studied had values between 13 643 J / g to 18 842 J / g, especially if Pie castanets due to the higher amounts of available energy both in its fresh form with values of 18 620 J / g or as briquettes with values of 18 842 J / g, values that are considered satisfactory for biomass waste. The ash content of the samples had values between 2.89% to 6.54% for the sample is fresh and in form of briquettes values that are considered acceptable...
