Biodigester Gas

Key Highlights:

• Benefits
  • Biodigesters capture methane– the strong greenhouse gas, thereby reducing the carbon footprint of dairy farms.
  • Reduces waste runoff and hence advocates principles of environmental and agricultural productivity.
  • Energy Independence and Cost Savings.
  • Improving Soils With Digestates.

Energy Independence and Cost Savings

• Using biogas, a source of energy produced from farm waste, small farmers can generate their own electricity, heat water, and operate farm machinery, diminishing their dependency on outside energy sources.
• Any surplus electricity can be fed into the local grid in addition to being another source of income for the farm.

Improving Soils With Digestates

• Digestate is a product that comes out from anaerobic digestion that improves soil fertility and structure and consequently provides much healthier crop yields.
• It is odourless, on the low side is likely, so less chance to be infected with pathogens hence making application onto fields much safer and more environmental-friendly.

Recycling Economy

• Dairy farms are part of the circular economy on the reuse of waste.
• This integrated approach prepares the case for resource efficiency, waste reduction and resilience against shifting energy and fertiliser prices.

Barriers and Opportunities

• It needs upfront investment and technical know-how.
• The government incentives, the subsidies, and grant programs for renewable energy bring this technology a bit closer.
• Jugaad or collaboration between dairy cooperatives with agritech companies would, in coordination with banks and financial institutions, make biodigesters smoother.
