All ITC units monitor significant air emission parameters such as Particulate Matter (PM), Nitrogen Oxides (NOx) and Sulphur Dioxide (SO2) on a regular basis.

We made continuous improvements in this area and ensured that emission levels not only comply with statutory norms but also achieve international benchmarks. This was achieved through adoption of cleaner technology/fuel and state of the art pollution control equipment.

Our Bhadrachalam unit, the largest integrated paper/paperboard unit in India, accounts for a significant portion of ITC's total emissions.

In 2008-09, the specific NOx emission levels from the unit were better than the standards stipulated even in European countries.

Particulate Matter emissions from Bhadrachalam were 1.75kg/BDMT (Bone-Dry Metric Tonne) in 2008-09 whereas large-scale Indian mills typically emit 3.8 kg?BDMT - 'All About Paper - The life cycle of Indian Pulp and Paper Industry,' Green Rating Project by the Centre for Science and Environment, 2004.

Bhadrachalam also monitors Hydrogen Sulphide emitted. The average measured value for the year 2008-09 was 3.41 mg/Nm3, almost a third of the regulatory norm of 10mg/Nm3.

Changes adopt for a cleaner environment

All of ITC's units remain committed to benchmarking against international standards and to the implementation of state-of -the-art processes and technologies.

Some of the latest processes employed at Bhadrachalam are:
  1. Precipitated Calcium Carbonate Plant: This plant reduces the Carbon Dioxide emitted by the lime kiln into the air by 50%, by converting it into PCC
  2. Green Boiler - This boiler uses a bio-fuel-coal mix in the ration 70:30. Not only does it reduce our dependence on fossil fuel by almost a 100,000 tonnes per annum, it also helps find a productive use for bio-waste generated in the plantationss during debarking.
  3. Odour Control Initiatives - With the installation of the SUper Batch Cooking process, we have achieved zero emissions from cooking.
