Bengaluru startup Carbon Masters said its Harohalli waste-to-biogas plant is processing about 50 tonnes of municipal garbage daily while producing roughly one tonne of compressed biogas for commercial kitchens struggling with LPG shortages. Restaurants report the renewable fuel as a stopgap when cylinder deliveries slip during supply crunches.
Founders described partnerships with waste collectors and zoning approvals that took years before pipelines could serve industrial canteens. Environmental regulators monitor methane capture efficiency and digestate disposal used as fertilizer supplements.
City officials facing voter anger over garbage pileups view such plants as part of a broader circular economy strategy, though activists demand transparency about emissions and labor conditions for sorters.
Energy analysts said localized biogas cannot fully replace fossil cooking fuels at scale without grid investments, yet pilot success in Bengaluru may replicate in other metros confronting similar LPG volatility.
