19.5% reduction in specific wastewater at Bhadrachalam unit over the last year
14.8% reduction in specific wastewater at Kovai unit from the previous year
7.9% reduction of specific wastewater at Tribeni unit over 2008-2009
These three units are also already well within the norms (100 m3/tonne) of specific treated effluent discharge, as defined by Corporate Responsibility for Environmental Protection (CREP), a voluntary charter by the Ministry of Environment & Forests and the Central Pollution Control Board.
The National Productivity Council’s (NPC) Report on “Proposed Standard for Pulp and Paper Industries in India” recommends a benchmark standard of 50 m3/tonne for the Integrated Pulp and Paper industry. The current level of 48.0 m3/tonne at Bhadrachalam is better than the above mentioned benchmark.
Similarly, the above Report suggests a benchmark standard of 15m3/tonne for wastepaper based pulp and paper mills. The Kovai Unit, which belongs to this category, with treated effluent discharge of less than 7m3/tonne, has already surpassed this standard.
In the current year, the Adsorbable Organic Halides (AOX) (applicable only to our Bhadrachalam unit) level was a mere 0.0051 Kg per tonne of product (in 2008-09, it was 0.0074 Kg/tonne). The benchmarked performance of the Bhadrachalam unit, with respect to AOX levels, is illustrated below:
