“…Authors like Wang et al [ 38 ] reported similar values for N and S, although slightly higher (0.69 % and 0.01 %, respectively). Other positive aspect was the heating value, exceeding 18 MJ kg −1 , very similar value compared to those reported by Lopes Grotto et al [ 39 ] for rice husk from two types of genetically improved rice. Other authors, such as Su et al [ 3 ] reported an HHV value of slightly more than 15 kJ kg −1 .…”

Rice husks are a by-product that is generated in large quantities in Spain. However, they are not used efficiently. One of their possible applications is its thermal use in power generation equipment. For that purpose, it is important to know the characteristics of rice husks and their thermal behavior, as well as their possible pollutant emission to the atmosphere with respect to its thermal use as a biofuel. In this work, the thermal characteristics of rice husks and their thermal behavior were studied by using thermogravimetry and mass spectroscopy for two different atmospheres (oxidizing and inert). This way, the thermal profiles and the main characteristics were studied, as well as the emission of possible pollutants to the atmosphere, such as CO2, CH4, NO2, NH3, SO2, and H2S. Moreover, three different methods (FWO, KAS, and Starink) were used to carry out a thermal analysis, in order to obtain the main thermal parameters such as activation energy. The results of the analysis predicted that rice husks could be used as biofuel in industrial thermal equipment based on its acceptable calorific value, good thermal characteristics, and low gas emissions both in oxidizing and inert atmosphere (although they have a high ash content).

“…A Figura 6 apresenta os resultados para o poder calorífico superior (PCS) obtidos experimentalmente e relacionados aos resultados da análise imediata através da correlação (PARIKH et al, 2005) apresentada pela Equação 2. A análise do poder calorífico da biomassa indica a quantidade de energia ligada ao processo de combustão, sendo considerado como um parâmetro fundamental para medir a eficiência de um combustível (GROTTO et al, 2020) (HASAN et al, 2018;GAN et al, 2019).…”

There is an urgent need for energy sources with lower environmental impacts to dispose of waste generated by human activities. In this context, a holistic analysis of energy use of waste from agricultural and forestry activities, animal excreta, urban solid waste and sewage, waste from the pulp and paper industry and charcoal in Brazil is presented. Based on a bibliographic review, the current Brazilian panorama is presented in figures giving, a vision of national potential for harnessing bioenergy from this theoretical and technical potential. The QGIS3.24.2 Tisler geoprocessing tool was used to generate potentiality maps from census data of microregions and municipalities available in the IBGE database (2022) and in the Geocentric Reference System for the Americas (SIRGAS 2000). The results of map analysis by micro‐regions of the primary energy from agricultural residues highlight sugar cane, corn and soybeans crops, followed by wastewater and animal excreta. They stood out amont the studied sources of biomass with technical potentials of 53.17, 15.23 and 6.81 GW, respectively. With these results, it is concluded that Brazil could enable around 75 GW installed power, reusing all biomass, potentially 12.5 PJ, without considering the 16 GW already installed from sugarcane and paper black liquor plants.
