Tamil Nadu Village Turns Cow Dung to Electricity

Summary

In the village of Bhararajpuram, a biogas plant set up by Carbon Loop and the Thiruvalu District Rural Development Agency has transformed cow dung from waste into a valuable resource. Previously polluting the local river, cow dung is now collected and converted into electricity, powering streetlights and reducing the village's electricity costs. The project, costing ₹60 lakh, is expected to save ₹50,000 a month and plans to extend its benefits to charging electric vehicles. The leftover waste is also used as manure to support local agriculture, demonstrating an innovative approach to rural development.
