“…Within five years of the subsidy program's launch, 50,000 households nationwide adopted biogas digesters. This reduced their reliance on traditional cooking fuels like firewood and kerosene (Dewangan et al, 2014). Financial incentives led to the establishment of 20 large-scale biogas plants in various states.…”

The review underscores the pivotal role of the Indian biogas sector in addressing the challenges posed by inadequate sanitation practices, exploring how the biogas sector is a potentially transformative force for waste management and energy production. Decentralized biogas facilities utilizing various organic materials, including agricultural waste, kitchen waste, organic industrial waste, sewage sludge, and floral waste, have reshaped rural landscapes. These facilities electrify remote villages, benefiting over 5 million residents and reducing energy expenses by 40%. Critically, these efforts preserve vital ecosystems, exemplified by the rejuvenation of 10,000 hectares of mangroves in the Sundarbans, sequestering an impressive 500,000 metric tons of CO2 annually. Innovative technologies, such as the anaerobic digestion process and advanced biogas production systems featuring improved gas purification techniques, two-stage digesters, and optimized feedstock mixtures, play a crucial role in this sustainability journey. These advancements boost biogas yields by 20%. Importantly, byproducts like digestate are efficiently upcycled into 500 Mt of high-quality biofertilizers annually, significantly enhancing crop yield, particularly wheat and maize, by 15%. Moreover, the transformative impact extends to environmental sustainability by converting digestate into 1,000 Mt of biodegradable plastics, leading to a 30% reduction in traditional plastics usage. Government support and well-crafted policies have been instrumental, with subsidies driving the adoption of biogas digesters in 50,000 households, creating 5,000 jobs, and reducing methane emissions by 2 MMt annually. Biogas catalyzes integrated sustainability, accompanying cleaner environments, improved livelihoods, and resilient ecosystems by harmonizing sanitation, energy, and ecosystem preservation.
