Indian co Surat Milk cuts costs with dairy waste-to-gas system

Sep 28, 2012 - Indian company Surat Milk Producers Union Ltd has reached annual cost savings of more than INR 5.4 million (USD 102,000/EUR 79,000) thanks to the use of biogas produced in the fermentation of dairy waste, Times of India said.

The company is using the green gas in the manufacturing process for sweets. Its managing director Jayesh Desai told the newspaper that the waste-to-energy installation had helped it keep reasonable prices on its products.

Assistant manager marketing Dipak Bhatt explained how the technology works. The company is using digesters to separate the fat in dairy effluent from water. After the fat ferments the emitted biogas is stored and then compressed. A gas pressure regulation system transports the gas to the burners where Surat Milk makes the sweets.

Surat Milk, south Gujarat's biggest dairy producing co-operative according to the Times of India, has annual sales of INR 15 billion.
