Environmental Management

With a specialized team, formed by environmental engineers and technicians, Portonave has a number of programs and environmental monitoring initiatives aimed at preserving the environment.

The projects include the periodic control of indicators such as the quality of air, water, soil, acoustic comfort, and solid waste management, among others. As a result, the company strives to mitigate most of the environmental impacts that its activities may cause or to adequately offset inevitable impacts.

Waste Management

Portonave’s selective collection system covers all areas of the Terminal and ensures that waste produced is disposed of properly. Containers specific for recyclable, organic, non-recyclable and hazardous materials (such as batteries, medicines and e-waste) are available in various areas of the company. Waste is sent to an internal collection center to be then appropriately forwarded to specialized outsourced companies which will be responsible for the adequate disposal of said waste. Final disposal companies provide the certificate of final disposal (CFD) for each type of waste and, with this, it is possible to trace Portonave’s waste production.

Dealing with environmental emergencies

Portonave maintains a team to deal with environmental emergencies 24 hours a day. The team goes into action whenever a potential environmental emergency is identified, such as chemical spills on land and in the waters of the Itajaí-Açu river.

Drinking water monitoring

The drinking water monitoring program meets the requirements of Resolution RDC No. 72 of December 29, 2009 of the Brazilian Health Surveillance Agency (ANVISA). An experienced environmental management technician monitors water chlorine concentration daily, ensuring water quality and protecting the health of all who consume it. Every month, Portonave’s water supply is analyzed by a specialized laboratory to certify its drinkability.

Liquid effluent treatment and reuse of equipment washing water

The wastewater treatment plant treats 100% of sanitary waste generated in Portonave and effluents returned to the Itajaí-Açu River are within the standards required by environmental legislation. That process is monitored daily by a qualified environmental management technician. In addition, water used to wash company equipment goes through a treatment system, enabling its reuse and contributing to save natural resources.

Drainage Channel

Portonave has a drainage system which directs all rainwater to a waterproof channel with a floodgate. The gate is closed to prevent channel water to come in contact with the river. The water of the drainage channel is analyzed daily by a qualified environmental management technician and it is only released in the Itajaí-Açu River after attesting the absence of any contamination. In cases of polluting product spilling in Portonave’s yard, for example, it is possible to keep the floodgate closed until the emergency service is finalized.

Monitoring of ground, sea and estuarine water

Groundwater in Portonave’s area is analyzed on a monthly basis through collection in piezometric wells. Samples are sent to specialized laboratories. This analysis allows identifying groundwater contamination by chemicals or oil byproducts.

In addition, the Terminal’s environmental team periodically monitors the water of the Itajaí-Açu River. The result of the analysis makes it possible to evaluate the estuary and identify possible contamination.

Air quality monitoring

Portonave uses last-generation equipment to periodically monitor air quality, measuring the concentration of CO (carbon monoxide), NOx (nitrogen oxide) and smoke blackening directly in the exhaust of third-party trucks which access the Terminal. Trucks are checked by sampling. Portonave’s internal equipment and vehicle fleet is also monitored and evaluated on a daily basis. Results are compiled and prevention and correction actions are taken whenever excess dust is identified.

Noise monitoring

The noise monitoring program aims to identify the generation of noise from port operations and minimize the environmental impact on the surrounding communities. Every month, an environmental technician monitors the noise in Portonave’s entire area. Port equipment is also evaluated weekly to prevent that its noise disturbs the community.

Environmental Recovery

Portonave maintains a green area composed of native forest species in its perimeter. This area was created to mitigate part of the noise generated and form a habitat for local wildlife.

The environmental recovery program also involves the rescue of animals found in the operational area. Sick animals are catalogued and sent to recovery centers. Exotic animals are sent to regional zoos and native animals are rescued and released in the permanent preservation area.
