Water

Ensure water availability and access to quality water for the various users of the river basins where we operate, based on environmental education, protection of springs, water monitoring, reduction in abstraction, risk analysis and mitigation of impacts from our operations on this resource.

  • Management of water and effluents in forestry operations

    Context:

    The intelligent use of water is a priority in Suzano’s investments, as we understand that this is an important natural resource for the balance of our ecosystems and the continuity of our business. In this sense, we perform regular measurements of quali-quantitative parameters of the main river basins where we operate and adopt forest management technologies that favor the efficient use of water resources within these river basins, which helps us reduce the risks of water shortage in neighboring operations and communities.

    In order to better assess the effects of climate on the productivity of forests and to reduce risks in periods of water scarcity, the company has a network of 89 meteorological stations across all forest management units. The information generated is used to assess different scenarios about the impacts of climate change on our forest management and the availability of water resources. In addition, specific studies are conducted based on our Open Air Laboratories (Laboratórios a Céu Aberto), composed of a network of six flow towers (Eddy Covariance system), located in the forests in the states of São Paulo, Espírito Santo, Maranhão and Mato Grosso do Sul. This technological apparatus allows us to monitor in detail the growth of the forest and its interaction with the climate on a daily basis, enabling agile decision-making in the event of adversities.

    Also, in order to advance its processes and improve the notion that natural resources can and should be harmoniously shared with other users, Suzano has made a long-term commitment to implement specific actions in watersheds identified as critical, seeking to increase the availability of water in these locations. The assessment of supply and possible water scarcity is being conducted considering a historical series of water data, as well as environmental and social characteristics of all river basins in Suzano’s forest base. The results, to be released in 2020, will be used to prepare the baseline to gauge the evolution of the long-term goal.

  • Management of water and effluents in industrial operations

    Context:

    Committed to the protection of natural resources, our water management seeks greater efficiency in production processes and in new engineering projects, in addition to raising awareness among our employees on the use of water.

    In the industrial areas, we work to meet and exceed legal requirements while maintaining optimal operating conditions in the processes. To this end, we continuously monitor the control parameters, such as specific water abstraction, recirculation in processes and quality of the effluents treated. The information and data generated are reported periodically to the teams involved in implementing improvements. This is done through an integrated management system, formally communicated to state environmental agencies.

    In order to reduce water abstraction, our units work on various initiatives to raise awareness among the teams involved in managing these resources, encouraging the implementation of practical actions for recycling and reusing water and continuous process improvements through procedures, standards and technology.

    As an example of these fronts, the Mucuri unit focuses its initiatives on closing circuits, improving washing efficiency, using water from the air conditioning system, heat exchange systems and a strong environmental education process for the conscious use of this natural resource.

    In Jacareí, about 85% of the water abstracted is recirculated in the production process itself before being treated and returned to the environment. This recirculation takes place through internal reuse, such as with cooling water, condensates (steam), bleaching filtrates and white water from dryers, in addition to internal recirculations in the Water Treatment Plant (WTP).

    At the Três Lagoas unit, positive results were achieved after adjustments to the evaporative condenser, improvements in purging controls and implementation of cycle control in the cooling towers, in addition to internal water recovery at the WTP itself, with treatment and reuse of backwash water.

    Another very important action performed by Suzano in this regard is its participation in local river basin committees, to discuss the use of water together with representatives of the Government, companies and civil society. In this sense, through our local teams, we participate in the following committees:

     

    • Alto Tietê River Basin Committee (SP);
    • Rio Doce River Basin Committee (MG/ES);
    • Litoral Centro Norte River Basin Committee (ES);
    • Paraíba do Sul River Basin Committee (MG/RJ/SP);
    • Piracicaba, Capivari and Jundiaí River Basin Committee (SP).

     

    Also noteworthy is the participation in the Crisis Committee of the National Water Agency (ANA) for the Tocantins River.

    With regard to Suzano’s public commitments on this matter, in 2019, the company defined long-term goals related to the use of water resources in our operations, involving reduction in water abstraction and consumption in industrial units, as provided in “Long-term goals” of this Indicators Center (item “Water”).

  • Percentage of water recycled or reused in industrial operations

    Context:

    On average, Suzano’s units operate with a recycled or reused water capacity between 75% and 80%.
