The methodology applied included the collection and statistical analysis of data on air pollutants, such as PM1.0, PM2.5 and PM10, comparing them with the standards established by CONAMA Resolution No. 506/2024. The results indicated that the annual average of pollutants was below the permitted limits, showing that, in general, air quality in the city is considered good, although variations occur during periods of high traffic and weather events. It is concluded that, despite some temporary peaks of excess pollution, the trend is towards compliance with environmental standards. However, it is essential to carry out further investigations on an ongoing basis on the calibration of the sensors and to deepen studies on the influence of climate variables on air quality, in order to ensure more accurate monitoring.

The biological transformation of these residues generates methane, the main component of biogas, whose release into the atmosphere contributes to the greenhouse effect and global warming. Thus, mitigating greenhouse gas (GHG) emissions, such as carbon dioxide, methane, and nitrous oxide, is a crucial aspect of this research. To assess biogas production, the Biochemical Methane Potential (BMP) test was applied, quantifying the biodegradability of the waste based on total CH₄ production. The experiment involved introducing fractions of solid waste, a culture medium, and an inoculum rich in anaerobic microorganisms, accelerating the bio-stabilization process and increasing the efficiency of anaerobic digestion. Additionally, the nutrient solution used helped regulate pH, reducing the time required for system stabilization. The results enabled the assessment of the energy feasibility of the biogas generated, reinforcing the importance of utilizing these residues for sustainable energy production.
