After trying various business options, Delhi School of Engineering alumni Neha Juneja and Ankit Mathur hit upon creating a cooking stove for rural households. They registered Greenway Grameen Infra (GGI) in 2010 and started selling the Greenway smart stove the following year. Compared to the mud chulha used by 160 million rural households in India, the GGI stove burns 70% less fuel and has much less emission. “There is a Rs.10,000 crore market for such products,” says Juneja.

The cost of a chulha is Rs.1,250 and GGI had sold some 6,000 so far. At present, GGI works as a social enterprise in collaboration with various institutes and NGOs. Next on the cards is a bigger, better version of the GGI smart stove. “Our new stove will be much cleaner and will be exactly like using LPG,” says Juneja. Also on the cards is a device to covert waste heat into electricity.
