Compressed Biogas (CBG) Landscape in India
摘要
In India, the history of biogas plants using cow dung (gobar gas plants) dates to 1859, when the first anaerobic digesters were installed in 1859 for biogas illumination. In 1946 Indian Agricultural Research Institute (IARI) developed a batch-type cattle dung digester, but its high cost hindered widespread adoption. Research continued to improve cost-effectiveness and gas production. The second phase (1950–1960) saw contributions from Jasbhai J. Patel and the IARI group. Patel designed the Gram Laxmi gas plant, patented in 1951, featuring a rotating gasholder and a continuous digestion system.
