Delhi Chief Minister Rekha Gupta has called for the identification of suitable land near urban dairy clusters to establish bio‑CNG plants, promoting conversion of dairy and wet waste into clean energy. The government will work closely with Delhi’s Milk & Dairy Development Department and the Municipal Corporation to locate sites capable of processing dairy effluent and cattle dung, integrating them with existing solid waste treatment systems.
Under this proposed model, dairy cluster by-products would be co-digested with urban wet waste in anaerobic digesters (200–300 T/day). The resulting bio‑CNG would fuel public and municipal vehicles, support city heating, and enhance energy self-sufficiency.
This initiative aligns with existing efforts—three bio‑CNG plants are already in development in Narela‑Ghogha, Okhla, and Hastsal, processing 100–300 T/day of wet waste and producing approximately 8 T/day of bio‑CNG per plant. Integrating dairy waste is expected to boost gas yield and reduce environmental footprint, offering dairy farmers a sustainable waste management solution while cutting Delhi’s methane emissions.
Industry Insight:
For dairy processors and co‑op federations, this presents an opportunity to monetize waste streams, participate in circular bio‑economy projects, and secure alternative revenue from CNG credits—while aligning with national sustainability mandates and the SATAT/CBO policy framework.
