Significant Air Emissions
Monitoring combustion efficiencies to achieve lower specific emissions
Investments in state-of-the-art pollution control equipment
ITC continued to invest in reducing air emission levels through adoption of cleaner technologies/fuels, monitoring of combustion efficiencies and investment in state-of-the-art pollution control equipment, such as plasma filters and electrostatic precipitators.
All our Units monitor significant air emission parameters, such as Particulate Matter (PM), Nitrogen Oxides (NOX) and Sulphur Dioxide (SO2) on a regular basis to ensure compliance with internal norms that are more stringent than regulatory requirements.
In 2012-13, the total significant air emissions included 690 tonnes of PM, 649 tonnes of NOX and 790 tonnes of SO2 emission (in 2011- 12, PM: 701, NOX: 732 and SO2: 841 tonnes). The decrease in the total emissions over last year is due to the reduced use of internally generated energy from fossil fuels in ITC and increased energy utilisation from ITC owned wind farms.
In 2012-13, PM emission from Bhadrachalam was 0.96 kg per BDMT (Bone-Dry Metric Tonne) of production, an improvement of 4.1% over the previous year (1.00 kg/BDMT in 2011-12). 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 2012-13, the specific NOX emission in Bhadrachalam was better than the standards stipulated in European countries, as illustrated below:
