Solid-waste treatment

Waste Treatment Center

The CTR Rio was created to replace the old controlled Gramacho landfill and started operations in April 2011, on a 3-million square meter plot of land, located in the city of Seropédica (Rio de Janeiro state).
We planned and executed the environmental project by implementing cutting-edge technology to ensure that there was no contamination of soil or air. Today, the CTR Rio is one of the most advanced treatment centers in Latin America.
Through a concession from Comlurb, the plant receives and treats approximately 10,000 tons of solid waste daily from Rio de Janeiro and from the municipalities of Seropédica, Itaguaí, Mangaratiba, São João de Meriti, Piraí and Miguel Pereira.
To guarantee additional safety for the environment, we waterproofed the landfill's soil with four layers of protection, using clay, GCL (bentonite geocomposite), and a double layer of high-density polyethylene sheets. We also use electronic sensors that can detect anomalies in the waterproofing system.

Through the leachate drains in the bioenergetics landfill, we prevent pollutants from contaminating the soil. Thus, all the leachate generated is sent for treatment at the existing Leachate Treatment Station within the CTR.
The plant also has a network of monitoring wells to assess the quality of groundwater and monitor against possible contamination.

The existence of a solution like that of Ciclus Ambiental allowed for the closure of the Itaguaí and Seropédica dumps, in addition to the latter's environmental recovery.
