‘Vaayu’ is a biogas technology, which generates Methane gas from organic waste,  which can be used directly as a cooking and heating fuel.

PUNE: Chinchwad-based social business firm Vishwadeep Press Part has come up with a technology to make biogas by processing kitchen (organic) waste. Priyadarshan Sahasrabuddhe, owner of Vishwadeep Press Part, started this initiative in 2014. The unit, named ‘Vaayu’  is serving 70 households in Pune and 130 in Maharashtra. 

‘Vaayu’ is a biogas technology, which generates Methane gas from organic waste,  which can be used directly as a cooking and heating fuel.

Sahasrabuddhe said that the ‘Vaayu’ unit can be kept in balcony, terrace, garden or even in a spacious kitchen.

His company has also given training to a SWaCH ragpicker who is getting financial help from the technology. Working with SWaCH for last 15 years, Vidya Naiknavade got training to use Vaayu, in which she puts 7 kg kitchen waste from Suparna Mangal Karyalaya in Sahakar Nagar and gets 1,000 litre biogas in 30 minutes.

“This training gave me so much knowledge,” said Naiknavade, “I am surprised that gas can be produced from kitchen waste and can save money on LPG cylinders.”

ORGANIC WASTE UTILISED
There are two modules - 2 kg module which produces 200 litre gas and 7.5 kg module that produces 800-1,000 litre gas.

Apart from her own kitchen waste, Vibha Karmalkar is collecting waste from local vegetable vendors and residents of Gokul Society near Mhatre Bridge, to put in her 7 kg Vaayu module. 

She has not just used the fuel for her own kitchen, but she uses it to boil water for her laundry business. 

“The flame looks same as the LPG gas flame but there is no foul smell and best to use. Looking at the unit my most of my friends and relatives have also bought it,” Karmalkar said.

HOW VAAYU WORKS?
Vaayu works on a a bacterial process in which the carbohydrates in organic waste is converted to Methane gas. The bacteria are called Methanogens.
