Delhi Chief Minister Rekha Gupta on Tuesday, 7 July 2026, shared remarks by Union Home Minister Amit Shah announcing that the Delhi government has signed an agreement with the National Dairy Development Board (NDDB) to convert cattle dung into biogas and natural fertiliser, with a pledge that not a single kilogram of dung will henceforth be dumped into the Yamuna.

Context

Quoting Home Minister Amit Shah, CM Gupta's post states: 'Kejriwal and company har roz 1,500 metric ton gobar Yamuna ji mein dalti thi' — ('Kejriwal and company used to dump 1,500 metric tonnes of cattle dung into the Yamuna every day.'). Shah added that the Delhi government will now use that same dung to produce gas and natural fertiliser through the NDDB partnership. The remarks draw a sharp contrast between the previous Aam Aadmi Party (AAP) administration under Arvind Kejriwal and the current dispensation's stated environmental priorities.

The Yamuna has been one of India's most polluted urban rivers for decades, burdened by sewage discharge, industrial effluents, and solid waste dumping along its Delhi stretch. The river has been the subject of repeated directions from the Supreme Court and the National Green Tribunal, and has remained a flashpoint in Delhi's political discourse.

Policy Backdrop

The NDDB partnership aligns with the Centre's GOBARdhan scheme, launched in 2018 under the Swachh Bharat Mission, which promotes the conversion of cattle dung and organic waste into biogas and bio-fertiliser. The scheme has been replicated across several states, and the Delhi agreement, if implemented at scale, would mark one of its most prominent urban applications.

The Namami Gange programme, launched in 2014, also included dedicated components targeting the Yamuna as a major tributary. The current announcement positions the NDDB deal as a complementary measure addressing an upstream source of river contamination — cattle waste — that had not been systematically tackled in previous administrations.

Stakeholders and Impact

Delhi residents, dairy farmers, and Yamuna basin communities stand to be the primary beneficiaries if the project delivers on its stated goals. Urban dairy clusters in areas such as Ghazipur and Mehrauli generate large volumes of cattle waste daily, much of which has historically entered stormwater drains that feed into the Yamuna.

The NDDB, a statutory body under the Ministry of Fisheries, Animal Husbandry and Dairying, has established expertise in biogas infrastructure and waste-to-value models in rural settings. Its application to Delhi's urban dairy ecosystem would be a significant scaling exercise. Biogas produced under the project could supplement energy needs for local communities, while bio-fertiliser could be channelled to peri-urban agricultural belts.

What's Next

Key details — including the rollout timeline, plant capacity, and capital outlay — are yet to be made public. Observers will watch for supplementary budget allocations in the next Delhi Legislative Assembly session and quarterly water quality data from the Central Pollution Control Board (CPCB) as early indicators of on-ground progress.

The political framing of the announcement — attributing past pollution to the Kejriwal government — signals that Yamuna clean-up will remain a central campaign and governance narrative for the BJP in Delhi. Whether the NDDB agreement translates into measurable improvement in Yamuna water quality will be closely scrutinised by courts, civic groups, and the electorate alike.
