Discharge water flow (m3/t)
WATER USAGE | Ongoing improvements in the water recycling process, renewal and installation of new equipment, as well as heightened employee awareness are priorities at Lecta. They ensure that we continuously improving and more efficient in our water management.
The slight increases in water values in this period are due, essentially, to production stoppages and the change in the production mix at some of our mills.
Over the last ten years, the discharge water flow used in pulp and paper production was reduced by more than 13.4%.
WATER QUALITY | Two of the key indicators for measuring the quality of the water returned to the environment in the paper industry are Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS).
Since 2014, Lecta has continuously reduced COD values per ton (1.17 kg in 2017).
Lecta has reduced COD values by 27% since 2008 and the TSS values by 37% in the same period.
