    The increase in the demand for biogas plants has provided stable jobs for builders such that they have an income steadier than before.

    The cattle manure and other organic waste is mixed with water and added to the inlet.

    The inscription on the inlet serves transparency reasons. The tracking-unique-identity-code helps to keep quality standards up. 'myc' stands for myclimate.

    The biogas plant produces enough gas for the daily cooking needs.

The overall objective of this climate protection programme is the installation of domestic biodigesters as a clean, sustainable energy source throughout India. The biogas generated from cow dung replaces fuels that are currently used for domestic energy needs such as firewood or kerosene.

The first installations take place in Gulbarga, Yadgir and Bidar District in Karnataka State. The project encompasses to install biodigesters in 6,900 households. The biogas installations are fed with animal dung and kitchen wastewater. The generated gas is used for cooking. In addition, the slurry of the remaining manure serves as high quality fertiliser 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.

There is 75% less forests than there used to be. People recognize deforestation as a pressing problem, not only because there is less firewood but also because there is more erosion and stronger monsoons.

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.

My father was a small farmer. He advised me to do something to help the rural people.

The programme results in greenhouse gas (GHG) emission savings in the following ways: The biogas displaces GHG emissions from kerosene and fuel wood that used to be used for cooking. The biogas produced from cattle manure is a renewable source of energy. The biogas displaces 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.

It's my dream to become an agricultural officer so that I can work with the farmers and help them switch to organic farming.

SKG Sangha, local partner of myclimate, coordinates the programme throughout India installing the systems with the help of people from the households. SKG Sangha is a very experienced Indian non-governmental organisation working already over 20 years in this field of activity. 

IMPACTS AND BENEFITS ACHIEVED:

  • 30,000 people benefit from better air and from having to spend less time for collecting firewood.
  • 100 jobs have been created (masons, supervisors, quality controllers, project managers)
  • 5,500 people have been trained
  • 4,600 biodigesters have been installed so far.
  • Each biodigester avoids about 7.2 t CO2 and 4.8 t of wood per year.
