Biogas Plants for 9,000 Families

Project type: Biogas

Project location: Kolar District, Karnataka State, India

Annual CO₂ reduction: 45,650 t

The installation of domestic biogas plants substitutes the use of firewood and chemical fertilizers in the Karnataka region. In addition to the reduction of greenhouse gas emissions and less degradation of the forest people directly profit from higher crop yields and less indoor pollution. Moreover, the project will also reduce methane emissions from cattle manure.

The project installs domestic biogas plants in over 9,000 rural households in Karnataka State, India. The biogas installations are fed with animal dung and kitchen wastewater. The generated gas is then used for cooking. In addition, the slurry of the remaining manure serves as high quality fertilizer replacing chemical products. Traditionally, domestic energy needs for cooking in the project area are met with firewood and kerosene. The inefficient cook stoves that people traditionally use have a thermal efficiency of only eight to ten percent. Low family incomes make it impossible for local people to substitute this traditional fuel. This led already to a degradation of the forest cover in the districts. Moreover, domestic biogas installations have positive sustainable development effects such as alleviating the workload for women and children and easing health problems caused by indoor pollution. The biogas unit will be of either two or three cubic metre capacity depending on the number and type of cattle owned by the household and the number of people in the household.

7,600 biogas digesters have been constructed and handed over to families since the beginning of the project.

The project will result in greenhouse gas (GHG) emission savings in the following ways: The biogas will displace GHG emissions from kerosene and fuel wood that are currently used for cooking. The biogas produced from cattle manure is a renewable source of energy. The biogas will displace GHG emissions from cattle manure that is currently dumped in pits near the household. The cattle manure is dumped along with other waste such as straw from the cow shed, some kitchen waste, crop residues and other organic matter and liquids in the pit. This organic waste is never dry and does not get mixed therefore animal waste is decaying anaerobically and emitting methane.

Me and my kids had to spend 4 hours each day to collect firewood. Now, it takes us just 20 minutes to produce biogas. There is no smoke in my house anymore and I get a great fertilizer for growing our vegetables.

The biogas technology is tried and tested in rural India. SKG Sangha, an Indian non-governmental organisation, will implement the project. SKG Sangha has already successfully implemented over 100,000 biogas units in India over the last 18 years.

Impacts and benefits:

  • 44'000 beneficiaries
  • 7,600 biogas plants
  • 100,000 t wood saved and therefore not being deforested
  • 490 t chemical fertilizer avoided by bio fertilizer in 2016
  • 2.3 hours per day being saved by a family thanks to the plant
  • 1 plant saves 6 t CO2 per year
