MCD rolls out 10-plant biogas strategy to cut dairy pollution and protect the Yamuna.
Delhi’s Municipal Corporation (MCD) has unveiled an ambitious waste management plan that places dairy sector residues at the center of river conservation efforts. The strategy aims to prevent dairy waste — especially cattle dung and effluent from dairies and cow shelters — from entering the Yamuna through the city’s outdated drainage system, a contributor to water quality degradation.
At the core of the action plan is the construction of ten new biogas plants, designed to process significant volumes of dairy waste and convert it into renewable energy. These facilities range in capacity, including several 200-tonne-per-day (TPD) units at key sites like Ghazipur, Bhalswa, Mangolpuri, Rohini and Sagarpur, as well as smaller plants serving colonies such as Sri Ram Colony.
Complementing the biogas expansion, the MCD proposes installation of nine decentralized wastewater treatment plants (DSTPs) and a comprehensive overhaul of dairy colony drainage infrastructure at an estimated ₹34 crore. By building sedimentation chambers and revamping defunct drains, authorities aim to trap and treat cattle waste before it can flow into municipal sewers and ultimately into the Yamuna.
The plan also involves coordination with the National Dairy Development Board to enhance waste handling practices across the city’s dairy clusters, building on an existing biogas facility in Nangli that processes 200 TPD of dairy waste and two additional plants now under construction. This collaborative model signals a broader shift toward sustainable dairy waste valorization in India’s capital.
For dairy producers, processors and environmental analysts, Delhi’s initiative illustrates how circular economy principles — transforming organic waste into biogas and reducing pollution — can be integrated into urban dairy policy. The project dovetails with wider Yamuna rejuvenation goals, emphasizing renewable energy, improved sanitation infrastructure and pollution control.
