IIT-Delhi team helps Punjab re-use farm waste

An IIT-Delhi team has provided technical support to Asia's first biogas-based power plant which is now operating on paddy straw for large-scale biogas production in Fazilka, Punjab. 

Abhinav Trivedi, a doctoral fellow working under the guidance of Professor V K Vijay of Centre for Rural Development and Technology (CRDT) has developed this process that has better efficiency than conventional processes for biogas generation.

The system is based on 100% use of paddy straw and has been generating nearly 4,000 cubic metres per day of biogas from 10 tonnes of straw. This is in turn generating 1 MW power.

This sounds like welcome way out of the pollution mess that the capital has found itself in. Going by reports, 70% of Delhi's air pollution is due to stubble burning in Punjab, Haryana and other parts of north India.

Professor V K Vijay of Centre for Rural Development and Technology (CRDT) of IIT-D said paddy straw, if not burnt, could yield 2.181 million tonnes of oil equivalent or 25,365 gigaWatt hours per year. "Straw burning can be avoided through installation of commercial biogas industries by using these agro biomass for both power generation and bio-fertiliser production to enrich soil health."
