Our Legacy

One of India's Oldest and Most
Enduring Sugar Enterprises

Riga Sugar Co. Limited has a legacy of sugar manufacturing in North Bihar spanning over nine decades. Headquartered in Kolkata and operating its integrated sugar complex at Riga, District Sitamarhi, Bihar, the Company is today part of the Nirani group of companies — one of India's leading integrated sugar, ethanol and power producers.

Originally established in 1933 under British management by The Belsund Sugar & Industries Limited, the Riga sugar factory is among the oldest in the country.

Riga Sugar Co. Limited was incorporated on 2nd September 1980, and the sugar undertaking was vested in it under a Scheme of Arrangement sanctioned by the Hon'ble Calcutta High Court with effect from 1st October 1981. Over the decades, the factory grew steadily — from an initial cane-crushing capacity of 800 TCD to 5,000 TCD — and diversified into distillery, ethanol, co-generation of power and organic fertiliser, becoming a cornerstone of North Bihar's agro-industrial economy.
