    In 2020, the gross balance of effluents discharged increase by 5.4% 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 BOD per ton of product), Suzano achieved a reduction of 4.1%—from 0.47 kg/t in 2019 to 0.44 kg/t in 2020. These numbers are within the baseline range of international standards (between 0.3 and 1.5 kg/t) set out by the IPPC (Integrated Pollution, Prevention and Control 2015 – European Commission).
