Computational simulation and evaluation of the use of cooking oil for biodiesel generation in municipalities of southern Brazil

The present work aims to develop and evaluate a proposal of computational simulation submodels to evaluate the use of cooking oil in biodiesel generation to be used in selective waste collection trucks in some municipalities of the central region of Rio Grande do Sul. South. For the development of the models, the System Dynamics method was used. Mathematically, a System Dynamics model is a system of linear equations. In general, this system is too complex to be analytically solved, so numerical integration is used. Through Vensim, it was possible to develop, document, simulate and analyze the models, noting the environmental and social impact caused by the collection in the seven municipalities studied. Regarding the implementation in the Vensim simulator, historical data were used to verify the integration between the model component modules, as well as the results generated, since the outputs produced by the simulation model from real data provided to them were evaluated. The results were satisfactory and met the designers' expectations.
