Sustainability

We care for the environment
Aditya Birla Chemicals is committed to protecting the environment. We follow environment-friendly processes and adhere to global safety standards.

The company continuously adopts new processes and technologies in an attempt to minimise pollution and waste. We believe in using natural resources responsibly and disposing by-products safely.

We are actively involved in several environmental programmes and our environmental policy is regarded as one of the best in the business.

Green initiatives
Hydrogen: Fuel for telecom towers
Aditya Birla Group pioneered the idea to use hydrogen (by-product during the manufacturing process of caustic soda) as a fuel to power Idea Cellular's telecom towers. The 'Green Idea' initiative was launched in Nagda, to provide uninterrupted power supply to Idea's telecom towers, which would otherwise consume diesel to run its generators in the absence of grid supply.
Energy conservation at Grasim Industries

Power-saving initiatives are a major thrust area at Grasim Chemical Division (GRCD) as power costs constitute 60-65 per cent of the total manufacturing cost for caustic soda. Several efforts have been taken up including constant monitoring, periodic energy audits, installation of energy efficient equipment and technological upgradation to save energy.

There are also internal targets for reduction in energy consumption right from the business level down to the equipment level. A continued focus on clean and energy-efficient technology coupled with cost benefits assume top priority at GRCD.

One significant example of the division's commitment to this cause is its collaboration with Uhde (Germany) and AKCC (Japan) to convert mercury cell technology to an energy-efficient membrane cell technology as a green chemistry initiative.

The Uhde collaboration includes conversion of second, third and fourth generation electrolysers (which were installed earlier) to the latest fifth generation electrolyser to save power as well as operation cost. In the collaboration with AKCC, GRCD implements the latest zero gap technology, which is highly energy efficient. With these initiatives GRCD stands to be the best among chlor-alkali units in the world in terms of electrolysis.

Clean fuel technology
The use of hydrogen gas as fuel instead of furnace oil in the poly aluminium chloride powder dryer, caustic soda flakes heater and in the boiler plant during process steam production has successfully eliminated carbon dioxide emissions (200 tonnes/day).
Water conservation and management

Water conservation and management forms a critical aspect of sustainability at the unit as water is one of the major raw materials in the chemicals manufacturing process. The Chambal river is the main source for water at the chemical division of Grasim Industries (GRCD). The water drawn from the river is filtered by the Grasim Staple Fibre division.

Some of the measures implemented at GRCD for maximising the recycling and reuse of water are:

  • Condensate water, generated from the caustic concentration unit, after regular quality testing and polishing, is reused in brine process, thus saving upto 220KL of water a day.
  • Condensate water, generated from the caustic concentration unit, after regular quality testing and polishing, is reused in brine process, thus saving upto 220KL of water a day.
  • The upgradation of the collection and treatment system for sewage water is carried out for maximum conservation of water and also minimisation of effluent volume. The treated sewage water is used for gardening purposes within the industrial premises, thus saving upto 80KL of water a day.
  • Collection facilities have been set up at plant divisions for the collection of condensate water from the equipment. This ensures the reuse of steam and process condensate water, thus saving upto 50KL of water a day.
  • Ion exchange rinsing is carried out on a daily basis at the brine plant. The water used for rinsing, following use, is collected and reused in the brine process. This results in the saving of upto 40KL of water a day.
  • Settling pits for the collection of backwash water from the Demin plant have been built to remove settleable impurities. The water thus obtained is reused in the process, thus saving 25KL of water a day.
  • Water mapping (tracking water usage and taking steps to reduce water use and water conservation) is carried out at the entire complex.
  • The waste stream, following critical analysis is also reused/recycled in the following ways:
    • Chlorinated brine waste is recycled in the brine process
    • Condensate is recycled in the brine/caustic soda makeup system
    • Cooling water blowdown is used for gardening
    • Domestic waste is treated at the sewage treatment plant, and used for gardening in the secured land field area.
    • A rainwater harvesting system has been installed at the industrial and residential complex, which acts as a dependable water conservation measure for reducing the dependence of groundwater. A water reservoir of 40,000m3 capacity has been built for the storing of harvested rainwater.
Green field development
GRCD has developed green areas in and around the factory premises. A total of 4,745 saplings mainly of Neem, Paras, Pipal, Ashok, Bottle brush and Ficus Benzamina have been planted as part of the effort. The green cover has increased from 15 per cent of the total plant area in 2010-11 to 23 per cent in 2011-12. The regular maintenance of the green cover, including the proper planting of saplings and scheduled watering through uniform sprinkling devices has resulted in an increase in the plant survival rate from 65 per cent to 82 per cent.

Social responsibility
Opening of school for children of poor families
Aditya Birla Chemicals (India) in association with the Rotary Club of Rehla has pledged to provide support to children of below-poverty-line families in Jharkhand.

ABCIL, as a progressive measure, has set up a school in Garhwa road in Palamau, upto the third standard, which will be upgraded upto eighth standard in the near future. The principal objective behind opening of the school is to give financial support to poor people who were unable to send their children to school because of their poor financial condition. The school boasts of excellent teaching faculty and education is provided at a very nominal fee.
