Household Biodigesters in India

ABOUT

This project reduces methane emissions by transitioning families in rural areas of Maharashtra State of India from a wood-burning stove to a household biodigester. Biodigesters turn cow dung and human waste into methane gas and provide a cleaner, more efficient, sustainable fuel compared to that of a traditional wood-burning stove. In Maharashtra, 70% of households rely on firewood for cooking, which results in cutting local forests for fuel. Switching to a biodigester reduces the need for wood and reliance on local forests. Maharashtra's land-use patterns show a decrease in forest land cover and an increase in degraded land. The problem intensifies pressure from growing human and livestock populations and illegal and indiscriminate exploitation of forest resources. Degradation of forest lands exacerbates the existing problem of desertification: some forests are turning into open scrub. Livestock waste is shoveled into the biodigester that houses anaerobic microorganisms that feed on biodegradable material. When they break down the waste, the byproduct is methane gas that is used for fuel. The biodigester is sized according to the number of people in the household and the number of cattle owned by the family. For example, a biodigester with a capacity of 2 cubic meters is sufficient to provide cooking fuel for a family of four to five members. Without the biodigester, the methane from the cow waste would be released into the atmosphere as it decomposes and the forest would become further degraded with continued reliance on burning wood for fuel.

BENEFITS

  • Combats climate change by reducing emissions from methane, a greenhouse gas that would otherwise be released into the air from decaying cow dung, and instead uses it for fuel.
  • Preserves local and threatened forests: firewood usage has dropped by 93-95%.
  • Saves family income once spent on firewood and creates jobs that require the transfer of biogas technology and training.
  • Reduces toxic smoke in the home to create a cleaner home environment.
  • Provides a clean, organic fertilizer, richer in ammonia than manufactured fertilizers, that improve soil and crops.

VERIFICATIONS

Gold Standard was established in 2003 to ensure projects that reduced carbon emissions featured the highest levels of environmental integrity and also contributed to sustainable development. With the adoption of the Paris Climate Agreement and the Sustainable Development Goals, they launched a best practice standard for climate and sustainable development interventions, Gold Standard for the Global Goals, to maximize impact, creating value for people around the world and the planet we share.

UN SUSTAINABLE DEVELOPMENT GOALS
