Análise crítica das rotas de coleta de resíduos sólidos urbanos no bairro centro do município do Crato/CE

Abstract

The study has the objective of minimizing the distances travelled by the collection truck and the transportation of solid urban waste by those responsible for collecting garbage, which must cover all the streets (arches) of the Centro district in the municipality of Crato/CE, introducing an optimization model for improving the management of solid waste collection and transportation. In order to carry out this research, the conventional collection truck routes were considered, which are performed on alternate days and times of the week, pre-established by the work team. For this, the company uses two homogeneous compactor trucks (each one with capacity between 9 to 12 tons). The heuristic process of the case study will be developed by the Unmanned Chinese Postman Problem, which has the characteristic of pairing nodes of an uncorrected graph. It is concluded that the optimized routes allow to verify that a reduction of 10% in the total distance travelled can provide savings of R$ 34.000,00 / month referring to maintenance and fuel costs of the vehicles
