It was used as a case study the municipality of São Gonçalo, located in the metropolitan region of Rio de Janeiro, with a population of over 1 million inhabitants. The objective of the work was to conduct a diagnosis of the current management of construction and demolition waste (CDW) from the data raised by the prefecture, to the concessionaire companies of the final collection and disposal services of solid waste, to private enterprises operating in the final provision of the CDW and the construction companies that are undertakings in the building phase in the municipality, as a basis for evaluating the difficulties that a large municipality, such as São Gonçalo, finds in fulfilling the legislation. Questionnaires were made submitted to the different actors involved with the management of CDW.
