hygienisation is quintessential in the context of dense urban centres. The preliminary assessment of the irradiation-based dry sludge hygienisation facility located at
Ahmedabad indicates that such a facility has a definite potential to be replicated in
other metropolitan cities, as well as, growing Tier-II cities. A case study for Bengaluru
ensures that such a sludge hygienisation facility would facilitate a safer management
of the municipal sewage sludge by making it pathogen free. Furthermore, as the irradiated dry sludge is usually rich in organic carbon, hence, the use of irradiated dry
sludge as the bio-fertilizer, upon being enriched by plant growth promoting bacteria,
would help in restoring the health of the otherwise carbon-deficient soil. Overall,
such a facility will enhance the cleanliness as well as, the greenness of the densely
populated Indian urban settings.
Acknowledgements The author would like to extend sincere gratitude to Dr. Virendra Kumar
(Head, AMS, RTDD, BARC) and to Shri Sudhir Dave (Consultant, AMC) for their invaluable
inputs and words of advice. The author is also grateful to the officials of the two STPs in Bengaluru
(KC Valley STP and Kadubeesanahalli STP), as well as, the Pirana Road STP in Ahmedabad for
the cordial interactions.
