Aditya Birla Chemicals (India) Limited (formerly Bihar Caustic and Chemicals Limited) was incorporated as a joint venture of the Aditya Birla Group and the Bihar State Industrial Development Corporation. The unit was set up with the objective of catering to the caustic soda requirements of Hindalco Industries Limited, and to contribute towards the economic development of the backward region of Palamu district in Jharkhand.

Commissioned in 1984 with an initial caustic soda capacity of 33,000tpa, the company has since grown to become the leading caustic soda producer in the eastern region of the country. The company had commissioned a 30mw captive power plant in the year 2000 and simultaneously, the caustic plant capacity was enhanced to 51,048tpa. In the year 2006, the capacity was increased to 78,750tpa by converting the mercury cell technology to the more environment-friendly membrane cell technology supplied by world-renowned technology supplier UHDENORA, Germany. Presently, the installed capacity stands at 105,000tpa.

For value addition and effective utilisation of chlorine, the company has commissioned a 12,000tpa aluminium chloride plant in the year 2007 and a 17,500tpa stable bleaching powder (SBP) plant in 2008. SBP is marketed under the brand name Shaktiman. Aluminium chloride is the principal catalyst used in the Friedel Craft reaction and widely used in pharmaceuticals, chemical intermediates, agrochemicals, dyestuffs and pigments, hydrocarbon resins, flavours and fragrances. SBP is used in textile mills for bleaching, sanitation, sewage systems, tanning process, organic synthesis and other applications.

The first in the chlor-alkali sector of India to be accredited with certifications of ISO 9001, 14001, OHSAS 18001 and SA 8000, the company has been the recipient of several awards.
