1. Benefits of GOBAR-Dhan:

• GOBAR-Dhan helps in managing a major portion of solid waste in villages e., cattle dung and agricultural waste and promotes environmental sanitation.
• Substantially reduces vector-borne diseases and promotes public
• Promotes household income and saving as the use of biogas reduces the expenditure on
• Helps in generating organic manure which enhances agriculture and farm productivity
• Promotes employment and income generation opportunities for SHGs/ farmers
• Helps in reducing carbon emission and promotes environmental
• Helps to save foreign exchange by reducing the need for the import of natural

Benefits of Biogas:

1. Health Benefits 

The advantages of a biogas plant for the health of a rural community are four-fold; uncovered faecal waste (animal) is  removed  from  open  areas, direct exposure of  people  to waste is eliminated. Therefore,   in   the   area   of public  health  and pollution control, where disposal of wastes is  usually  the major problem is easily eliminated. With that the associated health related problems are also eliminated. Dung waste are deposited directly into digester; the village is no longer littered with animal wastes, so hygiene immediately improves.

Digestion of these waste can reduce the parasitic and pathogenic bacteria counts up to 90%, breaking the vicious circle of infection via drinking water, which in  many  rural areas is untreated.

 As woman no longer have to spend hours away from their homes, traveling distances to collect wood for cooking and heating, they can free up valuable time for activities, which they would otherwise be unable to do. Their overall health improves due to better cooking conditions and decrease in respiratory diseases.

2. Agricultural benefits:

Biogas technology is  also  potentially  useful  in  the  recycling  of nutrients  back to the soil. Burning non-commercial fuel sources, such as dung and agricultural residues, in our country are used as fuel instead of as fertilizer, leading to a severe ecological imbalance, since the  nutrients,  nitrogen,  phosphorus, potassium and micro-nutrients, are essentially lost from the ecosystem. Biogas slurry preserves the nutrients, which can be recycled back to the land. The organic digested material also acts as a soil conditioner by contributing humus. The bio- slurry discharged from installation retains all the nutrients present in the original material, and it constitutes an excellent organic fertilizer. Normally fertilizing and conditioning soil can be achieved by simply using  the  raw manure  directly back to the land without fermenting it, but anaerobic digestion produces a better material. Proper application of this manure produces higher yields than nutrient depletion.

Biogas installation reduces the demand for firewood, mitigating deforestation. Applying bio-slurry as an organic fertilizer closes nutrients cycles, and halts soil degradation and erosion.

3. Environmental benefits:

Biogas plant improves air quality. Through Biogas plant, Methane gas is captured and utilized that would have otherwise entered into atmosphere from manure. Uncontrolled methane is a toxic greenhouse gas, 20 times more harmful to the atmosphere than carbon dioxide.

The biogas process is carbon neutral, contributing to the global reduction of greenhouse gas emissions. It helps controlling undesirable nutrients in soil and surface water supplies. It helps in reducing odour created by organic waste.

4. Resource benefits:

Production of energy (Gas and Manure); Energy generation plays a major role in supplementation small energy generation for Cooking, heating, and It lowers demand for natural gas and other finite supplies of fossil fuel. It being up to 100 percent renewable reduces dependence upon finite fossil fuels. It provides economic  benefits through energy and fertilizer substitution. It provides additional income sources and increasing yields of animal husbandry and agriculture.

It has the potential to provide large- scale generation of rural employment for local masons, unskilled labours, supervisors, turnkey workers and biogas accessory manufacturers; all roles’ women can fulfil as well as men. In this way, rural communities have greater opportunities to earn a living and become self- reliant and in turn conserve and protect their local environment.

5. Reduction of the Greenhouse Effect:

Last but not least, biogas technology takes part in the global struggle against the greenhouse effect by reducing the release of CO2 from burning fossil fuel in two ways. First, biogas is a direct substitute for gas or coal for cooking, heating. Second, the reduction in the consumption of artificial fertilizer avoids carbon dioxide emissions that would otherwise come from the fertilizer –producing industries.

Methane, the main component of biogas is itself a greenhouse gas with a much higher “greenhouse potential” than CO2. Converting methane to carbon dioxide through combustion is another contribution of biogas technology in the mitigation of  global warming. However, this holds true only for the case that the material used for biogas generation would otherwise undergo anaerobic decomposition, thereby releasing methane into the atmosphere. There is no net intake of carbon dioxide in the  atmosphere  from biogas burning, as is the case when burning fossil fuels.

All these attributes make Biogas Technology a clean technology and apt candidate for benefits of Carbon Credits under Clean Development Mechanism.
