Complete brownfield mill at CMPC Celulose Riograndense, Brazil
Aug 12, 2015
The new pulp line is an expansion to the existing Guaíba pulp mill in Rio Grande do Sul state, south of Brazil. The new line has a capacity of 1.3 million tonnes per year and can be upgraded to reach 1.5 million tonnes per year with minor investments. This is an addition to the existing capacity of the mill of 500,000 tons per year.
We consider the project to be victorious, and it has brought environmental gains to our company.
