Significant Effluent Discharges

ITC units continue to improve the quality of effluent discharges to minimise adverse impact on the environment.

Almost all ITC units have state-of-the-art effluent treatment
facilities to reduce undesirable effluent characteristics and the quality of treated waste water is significantly better than statutory standards.

   
In 2005-06, of the total 20.96 million KL wastewater, 86.8% (18.19 million KL) was used for irrigation. 8.4% (1.76 million KL) was discharged to surface water bodies and balance 4.8% to the municipal drains/sewage.

The Bhadrachalam, Tribeni and Kovai units contributed 19.95 million KL of the total treated wastewater discharged. Average monitored effluent levels in these units, in 2005-06, were substantially lower than the National Standards:

The average Adsorbable Organic Halides (AOX) level in Bhadrachalam effluents was 0.0025 kg/tonne of paperboard. This is remarkably below the average discharge level of 2kg/tonne by Indian Paper/Paperboard mills. It is also significantly better than the World Bank guidelines for new paper mills which stipulate a level of 0.2kg/tonne.
   

All values average for the year
