Optimization in the transport and final disposal of urban waste: a proposal for readjustment in the State Plan for Solid Waste in RN

Solid waste, transshipment station, location of facilities, data envelopment analysis.

The New Legal Framework for Basic Sanitation (Law Nº 14.026/2020) in Brazil, set new deadlines for the extinction of dumps as a way of final disposal of solid waste. In the state of Rio Grande do Norte, the waste disposal situation has been gradually improving, however, many municipalities still use dumps as a form of final disposal, due to the high cost of implementing sanitary landfills. Aiming to solve this problem, intermunicipal consortiums emerged as a way to meet legal requirements regarding the final disposal of solid waste. Present in regionalizations, the consortiums are formed by a group of municipalities in which one is destined to receive the landfill and transshipment station are distributed in some municipalities as a way of facilitating the transport and temporary storage of solid waste. That said, this research aims to propose a new proposal for the relocation of transshipment station for three regionalizations in Rio Grande do Norte, through the application of the Location of facilities method, through a mathematical modeling set up according to the conditions and restrictions of the problem, as well as proposing an index by evaluating the efficiency of the RN's urban solid waste by applying the NDEA model. With the application of the developed modeling and the NDEA modeling, it is expected to find an optimal distribution of transshipment station with better economic viability and generate an index used by the state as an evaluator of the effectiveness of their waste management system, facilitator for the transfer of information between municipalities and governments, state and federal, promoting a comparison between the municipalities and using strategies adopted by benchmarking to improve the urban solid waste management of municipalities with inefficient.
