Cost analysis of the strategic planning of the integrated urban solid waste system in Campo Grande, Mato Grosso do Sul

ABSTRACT

The worldwide trend of population growth and municipal solid waste generation suggests the application of tools to assess the sustainability of management systems, aiming at more conscious decision-making. The arrival of the circular economy concept and the Brazilian National Solid Waste Policy aroused discussions and greater concern with the products’ life cycle and waste reduction. Thus, the present study aimed to economically evaluate the strategic planning of the urban solid waste management system in Campo Grande, Mato Grosso do Sul, complementing the analysis of environmental impacts previously carried out, aiming to support sustainable decision making. Results showed that the landfill with energy recovery, despite being environmentally favorable, is not economically viable for the local reality. Investments in improving the efficiency of selective collection and sorting of recyclables, as well as a composting unit, are environmentally beneficial and profitable, despite the significant costs involved. It was concluded, then, that the Campo Grande Selective Collection Plan has realistic and environmentally and economically feasible goals that must be implemented urgently in order to improve the quality of life of the population and reduce environmental impacts, both locally and globally.
