The article presents the development, validation and experimentation of simulation model using systems dynamics methodology, which allows users and managers to evaluate and analyse scenarios about the generation and disposal of urban solid waste. The developed model takes into account the following rates and information: rate of population natural increase (births and deaths), percentage of urban solid waste sent to each type of final disposal and the quantity of waste generated per inhabitant. The simulated scenarios take into account three distinct situations: a) current scenario with varying rates; b) current scenario with static rates; c) scenario with rates similar to the Netherlands’s. The model’s validation was developed through the analysis of future scenarios for a municipality in Brazil’s southern region. With the generated results, the area managers may, in advance, evaluate and decide possible ways for improvements or adjustments in the management of municipal solid waste. The best simulated scenario was with rates similar to the Netherlands’s. For the system modelling and development Vensim simulator was used.
