Two firms have submitted proposals for a concession to manage municipal solid waste in the city of Salto in the state of São Paulo, Brazil.

The two firms are Revita Engenharia S.A., a subsidiary of Grupo Solví, and Corpus Saneamento e Obras Ltda. 

Corpus Saneamento e Obras was hired to develop the concession's feasibility studies in 2013.

The concession is for a period of 30 years. The PPP contract includes street cleaning, solid waste handling, treatment and disposal, including medical and civil construction waste.

The contract will be awarded to the bidder with the best technical and price offer. A ceiling price of Rs2.93 million per month has been set.

Salto, which has approximately 105,569 residents, is located 105km northwest of state capital São Paulo.

On 8 July 2014 we reported that Brazil's Minas Gerais and Consórcio Metropolitano de Tratamento de Resíduos (CMTR) had signed the administrative concession for the treatment of solid waste in Metropolitan Region of Belo Horizonte. CMTR is formed by  several local companies: Vital Engenharia, a company specialized in integrated waste management, Revita Engenharia and Construtora Barbosa Mello, a construction company.

The 30 years concession involves the treatment of solid waste in 43 municipalities of the Metropolitan Region of Belo Horizonte, which has a population of about 3 million people and produces about 3 million tonnes of waste per day. The project also involves the design, build, finance operation and maintenance of a new waste treatment plant for a period of 30 years.
