    1. In 2020, the Suzano Unit started to monitor AOX. Routine measurements are also planned for Rio Verde, Limeira and Belém. Units with values not disclosed (n/d) did not perform monitoring in the period.

    Additional information:

    In 2020, the gross balance of AOX in discharged effluents increase by 16% compared with 2019. This reflects the 9.9% increase in production in the same period, mainly concentrated in the Imperatriz, Mucuri and Aracruz Units.

    In specific terms (kg of AOX per ton of product), Suzano kept the same result obtained in 2019 of 0.05 kg/t. The value is well below the minimum reference of international standards (up to 2.5 kg/t), established by the IPPC (Integrated Pollution, Prevention and Control 2015 – European Commission), and of the most restrictive standards (up to 0.16 kg/t ), such as those defined by the USEPA (United States Environmental Protection Agency) and the target established internally (equal to or below 0.15 kg/t).
