We do not dispose of or drain water that
significantly affects water bodies, habitats or
areas of high environmental sensitivity. We have
a specific procedure for the management of
effluents at the corporate and operational level,
with control, by volume and type, in all activities
with the potential to generate industrial, sanitary
and oily effluents. In cases of disposal to a third-
party company, we require proof of licensing for
the activity and proof that the final disposal is in
accordance with the legislation - federal, state
and municipal, with emphasis on compliance with
Conama Resolution 430/2011 on the disposal of
effluents - and with our internal requirements. In
addition, we operate our own Effluent Treatment
Stations and apply effluent monitoring and quality
control programs before final disposal. The raw
material is always returned in better quality
conditions than it was in the capture stage.
In 2021, 7,449 ML of effluents were generated,
considering all activities (power generation, E&P
and works), representing an increase of 117%
due to the lower dispatch in 2020 resulting from
the Covid-19 scenario and higher dispatch of
thermoelectric plants in 2021, due to the water
scarcity situation.
