1. The Fertiliser Corporation of India Limited (FCI)

The FCI was established in 1961 to take over the management of Sindri and Nangal (Punjab) fertiliser factories. Now the Fertiliser Corporation of India has four units, one each at Sindri (Jharkhand), Gorakhpur (UP), Talcher (Odisha), and Ramagundam (Andhra Pradesh). The Gorakhpur plant has remained closed since 1990 due to obsolete technology.
