SUMMARY:

Energy is an essential factor for economic and social development. Increasing demand for energy has become a challenge to large production and consumption centers, as well as causing environmental problems, in this sense, their generation from renewable sources such as biomass is one of the most promising alternatives, and specifically residual biomass resulting from agroforestry activities has greater potential for exploitation. Brazil is the world's largest producer of annatto, accounting for more than 50% of the world's production, and in the processing of Bixa orellana fruits for the extraction of dye pigments such as bixin, large amounts of residues are produced without definite application. In this context the objective of the work will be the energetic characterization of the residues of the annatto processing. The analysis will be done from samples collected in a planting located in the city of Bonito / PE. Biomass was characterized by physicochemical characterization by Immediate Analysis (volatile content, moisture, fixed carbon and ash), Elemental Analysis, Compositional Analysis, Thermogravimetric Analysis, FT-IR and Calorific Power. The results show that the biomass has a satisfactory calorific value (15.04 MJ / Kg), low moisture content (9.71%), high percentage of volatile material (78.50%), and high content of lignin (32.15%) thus showing great potential for the energy use of this type of biomass.
