National Aluminium Company (Nalco) was incorporated in 1981, as a public sector enterprise under the Ministry of Mines.
The total capital cost of Rs 2408 crore was funded through the Government of India's contribution of Rs1289 crore and a euro-dollar loan from a consortium f Iinternational banks of Rs1119 crore.
The company has Asia's largest integrated aluminium complex, encompassing bauxite mining, alumina refining, aluminium smelting and casting, power generation, rail and port operations.
Commissioned during 1985-87, Nalco has emerged to be a star performer in production, export of alumina and aluminium, and more significantly, in propelling a self-sustained growth.
Nalco, since its inception, has taken adequate steps for pollution control and effective environment management.
Nalco's technology associate Aluminum Pechiney (AP), France, with its experience of stringent pollution control standards in Europe, has ensured eco-friendly process technology. With the growing environmental awareness in India and framing of stringent and statutory regulations, Nalco achieved all statutory clearances before starting its production.
Strict adherence to approved EMP and constant monitoring has helped Nalco to achieve considerable success in the field of environment management.
