The Greater Noida Authority is set to implement a solar-based sludge processing initiative using solar dry sludge management (SDSM) technology to enhance sustainable urban sewage management.

Officials announced that the pilot project will be launched at the 137 MLD Kasna sewage treatment plant (STP), the city’s largest. If successful, it will be replicated at STPs in Badalpur (two MLD), Ecotech-2 (15 MLD), and Ecotech-3 (20 MLD). SDSM technology uses solar power to dry sewage sludge in five days, converting it into a fine powder suitable for processing into organic compost, reducing waste load and enhancing reuse in horticulture. “The project aligns with broader sustainability goals and offers a clean, cost-effective way to manage sewage sludge,” said Vinod Kumar Sharma, Senior Manager, sewerage department.

The funding structure is yet to be finalised, and a detailed project report (DPR) is being prepared by IIT Delhi, expected within a week. Already piloted successfully in Goa, the model promotes waste-to-resource conversion, reduces chemical fertiliser dependency, and is expected to help meet Greater Noida’s growing sewage treatment needs while supporting a circular economy.
