Primo Tedesco runs its industrial activities based on the assumption that the impacts of its processes on the environment must be reduced by using clean technologies. To manage this, it permanently controls atmospheric emissions from its production process, with effluent treatment plants in all its mills and all solid wastes are disposed of in accordance with environmental legislation.

Control of Atmospheric Emissions

The company controls its atmospheric emissions in accordance with the norms in force of state organs of environmental inspection in the States where it has operations.

Control of Hydric Effluents

The company employs the most up-to-date methods to control hydric effluents generated by the manufacturing process of its products, and is constantly modernizing all its procedures and equipment to minimize any kind of pollution.
In the Pulp and Paper Business Unit, utmost importance is given to treatment of liquid effluents, because the preservation of the Peixe River, which flows around the plant, is very important for the preservation of the region's ecosystem.

The sector of effluent treatment consists of one primary treatment and another secondary. Consequently, in the first treatment all industrial rejects are returned to the process, and nothing is discharged into the environment. In the second treatment, the run-off from the first and effluents from soda chemical recovery and the cooking process are treated in a liquid stage which also returns to the production process and a solid part which is sent for dehydration of the sludge produced.The dehydrated sludge is sent to the landfill in accordance with environmental norms. This plant is equipped with a modern, liquid oxygen aeration system. This system is designed to reduce emissions of COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand) thanks to a sustainable system which operates below the limits established by environmental legislation.

In the Recycled Paper Plant a project to prevent effluent generation has been elaborated. Consequently, this plant works with a Closed Loop, that is to say zero effluents. Thus all the fiber and all the water used in the process of paper-making are re-used, resulting in significant economy in water consumption.

There is also no liquid discharge from production either at the Corrrugated Boxplant in Canoas or at the Santo Antonio do Planalto plant. The effluent treatment plant of this factory treats all the liquid waste generated by production, after which it can be re-used and nothing is lost to the environment.

Control of Solid Wastes

Primo Tedesco's industrial plants have procedures to separate, select and discharge solid wastes generated by the manufacturing process of its products. Industrial wastes are separated by type. After their separation, selection and treatment, each type of material is subject to regulations for its discharge as stipulated by environmental legislation. The companies contracted to receive the solid waste are specialized in this work and duly licensed by an environmental organ.
