Overview: Compressed Biogas Plant Industry in India
India’s compressed biogas industry is scaling rapidly under the SATAT and GOBARdhan initiatives, converting agricultural residue, cattle dung, press mud and municipal organic waste into clean fuel and organic manure. As of 13 August 2026, 1,929 CBG/Bio-CNG plants were registered nationwide, with 217 commissioned and 357 under construction. CBG can fuel vehicles, industrial energy needs and cooking, while reducing fossil-gas dependence and supporting rural incomes.
