Air Emissions

ITC continued to invest in reducing air emission levels by adopting cleaner technologies/ fuels, monitoring combustion efficiencies and investing in state-of-the-art pollution control equipment such as plasma filters, Electrostatic precipitators, etc.

All our Units monitor significant air emission parameters such as Particulate Matter (PM), Nitrogen Oxides (NO_x) and Sulphur Dioxide (SO₂) on a regular basis, to ensure compliance with our internal norms that are more stringent than regulatory requirements.

In 2009-2010, the total significant air emissions included 880 tonnes of Particulate matter (PM), 811 tonnes of NO_x and 909 tonnes of SO₂ emissions. (In 2008-2009, PM: 837tonnes, NO_x: 713 tonnes and SO₂:786 tonnes). The increase in the total emissions is mainly due to significant growth in production volumes in almost all Units in the following businesses; Paperboards and Specialty Papers: 15.3%, Packaging & Printing: 11.6%, Leaf Threshing: 6.6%, Foods: 5.2% in Biscuits & 7.4% in Snackfood, Personal care: 142% in Soap & 20.6% in Shampoo/Cream productions.

The Particulate Matter emissions from Bhadrachalam were 1.54 Kg per BDMT (Bone-Dry Metric Tonne) of production, an improvement of 12% over last year (1.75 kg/BDMT in 2008-2009). As per the Report by the Centre for Science & Environment, large-scale Indian mills typically emit 3.8 kg/BDMT (Source: ‘All About Paper - The life cycle of Indian Pulp and Paper Industry’, Green Rating project, 2004).

In 2009-2010, the specific NO_x emission in Bhadrachalam was better than the standards stipulated in European countries, as illustrated below:

Bhadrachalam	NO_x (Kg/tonne)
	2007- 08	2008- 09	2009- 10
	0.43	0.69	0.60
Standards
Sweden		1.2-2.4
EU		1.0-1.8
EU-BAT*		1.0-1.5
Reported Values
CEPI**		0.84

Bhadrachalam	SO₂ (Kg/tonne)
	2007- 08	2008- 09	2009- 1
	0.5	0.84	0.79
Standards
Sweden		0.5-1.4
EU		0.1-0.5
EU-BAT*		0.2-0.4
Reported Values
CEPI**		0.29

The Specific SO₂ emission levels of the Bhadrachalam Unit is comparable with international benchmarks and the Unit is working towards achieving these international standards.

In addition to the above parameters, the Bhadrachalam Unit also monitors Hydrogen Sulphide. The average measured value for the year 2009-2010 was 3.72 mg/ Nm³, considerably lower than the regulatory norm of 10 mg/ Nm³.

All other Units are also striving towards reducing specific emission levels.

The specific particulate emission in the leaf threshing business stands at 0.52 kg/tonne, marginally higher than last year (0.50 Kg/tonne in 2008-2009) due to the unavailability of high grade coal for power/steam generation.

11.3% improvement in specific emissions of NO_x in the Leaf Threshing business over last year

17.9% improvement in specific emissions of SO₂ in the Leaf Threshing business over last year
