India's Waste Problem Is Also an Energy Opportunity
India generates over 500 million tonnes of agricultural residue annually. Much of this biomass is burned in fields, contributing to severe air pollution and health hazards.
The nation depends on costly fossil fuel imports, exposing the economy to volatile global energy prices and supply disruptions.
Bio-CNG presents a strategic opportunity — converting agricultural waste into clean, domestically-produced transportation fuel while creating rural employment.
