Proposal of a sustainability index for intermunicipal cooperation on waste management.

The management of solid waste is one of the biggest challenges for sustainability. Aiming at gains of scale, guaranteeing universal access and the technical and economic viability of the services, intermunicipal cooperation has been implemented in several countries, and in Brazil, it presents itself as one of the main instruments of public policies in the sector of sanitation. The main objective of this article is to propose a set of indicators and the construction of an index to evaluate the performance of regionalized management of urban solid waste, applying them to intermunicipal public consortia operating in Brazil.
