The project consists in the construction of a pulp mill and energy plant in Punta Pereira, department of Colonia, Uruguay. The plant will have an annual production of 1.300.000 tons of bleached eucalyptus Kraft pulp, and a 180 MW generation capacity from biomass. The study consisted in the preparation and coordination of the Operational Environmental Management Plan for its submittal to the environmental agency for the granting of the environmental operational license. This plan will provide the prevention, control, minimization and/or compensation mechanisms of the potential environmental impacts caused by the plant operation. In addition, it will allow the implementation of an environmental performance integrated management system.
