Waste to energy: soluções teóricas adotando modelagem de equações estruturais

Abstract

In its latest report on the subject, the Brazilian Association of Public Cleaning and Special Waste Companies showed that Brazil is in a critical scenario in relation to the final destination given to urban solid waste (MSW). it is necessary to rethink the current management model. The use of MSW in the generation of electric energy is one of the viable alternatives adopted by about 20 sanitary landfills spread across the country that expands the energy matrix, which currently has the domain of hydroelectric plants. This work aims to develop a theoretical model through structural equation modeling to verify the dependence relationships between different MSW considerations and their application in electricity generation. Data were collected from the application of a questionnaire and the results show a strong correlation between the constructs: national plan for solid waste and energy capture through MSW. The database formed was applied in the SmartPLS software, which has a partial least squares (PLS) approach. The results obtained show that the biochemical treatment construct was the construct that had the strongest effect on the energy use of waste, showing that biochemical technologies are an interesting option to be used as a technological route for the energy use of waste products. MSW in Brazil. Finally, the modeling of structural equations, through the PLS approaches, in this case presented itself as a tool with indispensable notoriety to strengthen the areas of knowledge that present different relationships of dependence.
