Aterros sanitários municipais X consórcios públicos: a viabilidade econômica do consane

Abstract

One of the responsibilities the municipalities refers to urban waste (UW) disposal, an activity that is extremely burdensome to municipal coffers. Analyzing this issue through the associated services management (Intermunicipal Public Consortia) is fundamental when it comes to the scarcity of public resources. In this sense, the objective of this work is to evaluate the performance and assistance to the municipalities of the Regional Consortium of Basic Sanitation - CONSANE, towards the mandatory services concerning urban waste disposal. To this end, the history of the CONSANE arrangement, its current situation, population data and the solid waste management were surveyed. With these data, we estimated the landfill capacity to be built to meet the future demands of municipalities in a consortium and in a municipalized manner. The costs of implementing a landfill by each municipality singly would be uneconomical and could generate loss of invested resources. A savings of 56% of the total resources would be achieved by means of the consortium.
