What if part of a city’s waste could be treated as a resource rather than something that simply has to be carried away and dumped? That question became increasingly important in Udaipur, where about 220 tonnes of waste was generated every day in 2021, with 68% classified as organic. A smaller biomethanation project had already shown that this waste could be processed and turned into useful energy.
The experiment eventually led to something much larger. In February 2021, Udaipur began operating a 20-tonne-per-day biomethanation plant at the reclaimed Balicha dumping yard, producing Compressed Bio Gas, or CBG, for sale in the open market. The report is based on ICLEI South Asia “Building Climate Resilience in Indian Cities” compendium, specifically its Udaipur biomethanation case study.
