Abstract
. Fish production in the State of Maranhão is one of the most representative economic activities from the Brazilian coast. During the fishes processing, the amount of residues generated can reach 50% by mass of the total production. Fish scales are considered useless and impractical, being discarded in a disordered or unplanned manner in inappropriate places, such as in dumps or even thrown into the sea. The present study proposed to address this material in a sustainable and eco-friendly reuse, as a possible alternative energy source under thermochemical conversion processes for the bioenergy generation. The samples were prepared with an average granulometry (363 µm), and their chemical composition determined by ultimate analysis. The theoretical analysis performed under stoichiometric conditions allowed to estimate the main pollutants (CO2, NO and SO2), and the air mass necessary for the complete combustion of the fish scales. It was possible evaluating the influence of elements, e.g., nitrogen and sulfur from the sample composition in the generation of these gases, and the importance of carbon content in carbon dioxide emissions and air mass. Therefore, the information presented in this preliminary study can contribute as a basis for further experimental analysis in real thermal systems or on laboratory scale.
