(1) Urea Explanation: The Sindri factory was a Urea factory. It was the first in India to produce Ammonium Sulphate (1951), Urea (1959), and Ammonium Nitrate-Sulphate, commonly called the Double salt (1959). The Board of Industrial and Financial Restructuring (BIFR), in August 2012, approved the revival proposal of the closed fertilizer factory. A 5 million tonne integrated steel plant together with one 1.14 million tonne Gas based Urea fertilizer Plant and 500 MW Power Plant is being contemplated.
