Every year between October and November, the air quality deteriorates in Delhi and its neighboring states, caused by the burning of the agricultural residue by the farmers, after harvesting paddy to clear the fields for sowing wheat. Harmful air-contaminating gases such as carbon dioxide, sulfur dioxide, nitrogen dioxide along with particulate matter are released during stubble burning, posing it as the biggest contributor of air and soil pollution in Northern India.
The project primarily focuses on the in-situ utilization of stubble at the farms.The in-situ utilization of stubble consists of the formation of manure at farms and the generation of biogas in biogas plants. The in-situ utilization of stubble is a convenient, relatively less complicated, and more scalable way for creating great impacts.
The project also entails production of acoustic boards used for noise reduction in auditoriums, theatres, and sound studios. Stubble is also utilized for producing bio-briquettes, an alternative fuel for coal. The production of bio-briquettes envisions the reduction of over-dependence on coal, which is a non-renewable source of energy and a major contributor of harmful gases in the atmosphere. The project also utilizes stubble for producing paper, an initiative for curtailing deforestation.
Through this project, we anticipate reducing the air pollution and simultaneously producing profitable and cost-effective products using stubble, which otherwise is discarded and burnt posing potential environmental and health threats.
The project directly impacts local inhabitants, farmers and cattle raisers, biogas plant owners, and industries utilizing stubble for productive purposes. The people impacted indirectly are residents of Delhi and other parts of Northern India affected by the pollution caused by stubble burning.
The business model involves the four major parts :-
Collaborating with farmers indulged in stubble burning and convincing them to stop its practice.
Removing stubble from fields using SRM (Stubble Removal Machine).
In-site manure formation, biogas generation in family biogas plants.
To major biogas plants & factories to produce paper, briquettes, etc.

Our college mentor who is himself working on the project of Stubble Burning, has developed SRM (Stubble-Removal Machine) and SCT(Stubble Collecting Trolley) which is a cost-effective machine to cut stubble after harvest and load it into the trolley.
RS Farm, Bahadurpur
A farm in the village of Bahadurpur, which has over 150+ cows and two biogas plants of capacity 200 cubic metres each. The farm provides free biogas to the whole village for domestic use. The farm has collaborated with us to purchase stubble supplied by Enactus team and utilize it for generating biogas and feeding livestock.
