Comparação Dos Níveis De Poluentes Emitidos Pelos Diferentes Combustíveis Utilizados Para Cocção E Sua Influência No Aquecimento Global

Abstract: . Global warming is one of the most worrying environmental problems nowadays. A joint effort has been made by many countries to minimize greenhouse gas (GHG) emissions, responsible for global warming. The evidences indicate that global warming is occurring due to anthropogenic activities, mainly caused by the using of fossil or biomass fuels. Although this effect is more directly associated with external emissions, domestic emissions also have their contributions. In this way, cooking activities can have an im… Show more

“…It is also evident that C x H y and NO x emissions were higher in the curing units when E. dunnii firewood was used, which can be explained by two potential reasons: the possible higher amount of nitrogen in E. dunnii compared to in E. saligna, and the combustion that may have occurred at higher temperatures. The formation of NO x depends on the combustion temperature, the flow between the fuel, and the moisture [32], and is formed by breaking the bonds of nitrogen present in the fuel and the reaction with O 2 [33]. The emission curves of NO x and CO must be analyzed simultaneously, since the reduction of one pollutant can increase the formation of the other, as was also evidenced in this research [34].…”

“…As stated by Gioda (2018), in the biomass burning processes, incomplete combustion leads to the formation of gases such as carbon monoxide (CO), methane (CH4), nitrogen oxides (NOx) and sulfur oxides (SOx), organic compounds volatile (VOC) and particulate materials, arising from the decomposition of firewood in the ovens. For Alves et al (2015), the total emission of pollutants in food preparation results both from combustion and from the food itself, which generates volatilized organic substances (Kabir & Kim, 2011).…”

“…No século XXI está cada vez mais em evidência as preocupações com as mudanças climáticas e ambientais advindas da superexploração dos recursos naturais e da poluição. Os poluentes emitidos pela queima de combustíveis fósseis, além de causar danos à saúde, fazem parte dos compostos responsáveis pelo aquecimento global e alterações climáticas (Gioda 2018, ANP 2023e ANP 2020. Dessa forma, os biocombustíveis atuam como fontes de energia alternativa.…”
