Análise comparativa de resíduos sólidos urbanos (RSU) com potencial aplicabilidade em coprocessamento

Abstract

In the current context, with a view to changes in energy production, its use, and its impact on the global environmental landscape, the use of waste in co-processing contributes to reducing inadequate final disposal through the development of various studies, technological innovations, and experimentation. In this sense, calorific value analysis has proven to be a reliable, safe, and alternative method for energy recovery, already being adopted by most Eastern European countries, Japan, and the United States, to a lesser extent. Therefore, it is emphasized that any enterprise in this field must consider a combination of improvements in its technological, economic, environmental, and social approaches to mitigate potential future obstacles, aiming for its application in society. Therefore, this study aims to verify whether the tests performed in the laboratories comply with ISO 17025, through calorific value tests. Therefore, the procedures recommended in the manual available by the Solid Waste and Effluent Laboratory (LARSE) and the GUM and ISOBudget guides were used. According to the results obtained, the expanded uncertainties for four types of samples analyzed were obtained:34,779 ± 0,607; 11.814 ± 1.096; 25.354 ± 0.854; 18.365 ± 1.215; respectively, these values represent due to the differences in uncertainty regarding the repeatability of the experiment.
