Caroços de açaí (Euterpe oleracea m.) como alternativa energética para substituição da lenha na cocção alimentar em micro fornos de pizzarias. 2023. Trabalho de Conclusão de Curso (Bacharelado em Engenharia Ambiental e Sanitária) - Universidade do Estado do Pará, Belém, 2023.https://bibliotecadigitaldetcc.uepa.br/handle/riuepa/372In view of the problems of using firewood, such as the removal of vegetation generated to meet the demand for the production of the material and the environmental impacts of the generation of gases and particulates in the burning of biomass, the study proposes the replacement of this material by the açaí seed biomass. ground in commercial micro ovens. This waste has a high energy potential and great availability because it is marketed and discarded in various parts of the city of Belém. For this, the objective was to demonstrate the technical viability of using this biomass, through the determination of the hermophysical characteristics, to compare the environmental impacts of the emanation of gases and particulates from the materials and to point out the positive and negative impacts of the substitution. The initial results showed an apparent density of 0.5075 g.cm-3, as it is a crushed material with greater compaction. In addition, the material had a moisture content of 9.13%, fixed carbon content of 19.64%, volatile content of 79.10%, ash content of 1.27% and PCS of 4,601.80 Kcal.kg-1, proving to be a highly viable biomass for heat generation with a focus on food production. Furthermore, the study showed that the PCS, the amount of total energy and the energy density of this material, for comparison purposes, surpassed firewood, when based on consumption patterns in volume of firewood in the establishment. Regarding CO2, CO and particulate emissions, the comminuted material showed lower concentrations emitted for the last two contaminants. Therefore, the proposed biomass proved to be more energetically efficient than firewood and contributes to the mitigation of environmental impacts from the generation of polluting gases and to the reduction of waste accumulation in the city.Língua PortuguesaAbertoCrushed açaí seedEnergy efficiencyGases and particulatesArtigo Científico (TCC)
