In this case study, a problem related to the segregation and identification of waste was identified, and through the opinion of experts, the problem it could be solved through a technological scenario using technological dumps and financial incentives to encourage.In the second case study, the municipal manager reported a waste management problem related to the traceability of transport and packaging of the material. In this study, the decision maker selected through the multi-criteria methods on the implementation of a vehicle monitoring system in real time to track collecting vehicles. With the application of the model, it was observed that the steps can be applied in any context and the decision-makers can be different actors.
