Disadvantages Of Biogas
Biogas is a natural gas which is produced by the biological decomposition of manure
and other forms of organic matter like animal, water and weeds and other plants, in the absence of oxygen. It is combustible by nature and originates from biogenic material. It mainly consists of 2/3rd of about methane, 1/3rd of carbon dioxide, a little of hydrogen sulphide and a little hydrogen. Biogas can be used for the production of heat and electricity. India comes first in developing and using biogas technology. It is cheap, non-polluting and labor-saving fuel. Biogas can be used for cooking, lighting, and in vehicles. Solar energy, wind energy. Though the advantages of biogas are varied still it has got its own disadvantages too.
Biogas is a renewable source of energy. Biogas is a mixture of methane, carbon dioxide, hydrogen and hydrogen sulfide. The major constitute of biogas is methane, which is extremely good fuel. In fact, biogas contains up to 75% of methane gas which makes it an extremely good fuel. Biogas is produced by anaerobic degradation of animal wastes like cow-dung (or plant wastes) in the presence of water but in the absence of oxygen. Cow-dung and plant wastes contain a lot of complex carbon compounds like carbohydrates, proteins and fats. The anaerobic bacteria degrade (decompose) these carbon compounds to form methane gas, which is the main constituent of biogas.
The Disadvantages are as Follows:
The disadvantages of biogas are,
1. The capital outlays are high, that isthe high cost of refining biogas to the quality of natural gas. So the process is not attractive from the economic perspective, in comparison to other biofuels, on a large industrial scale.
2. As the value of biogas is rather low so it does not make a good commercial activity.
3. Biogascontains some gases as impurities, which are corrosive to the metal Paris of internal combustion engines.
4.The system works only if a large majority of the inhabitants participate, and can be attached to the local heating supply network for there is little or no control on the rate of gas production, although the gas can, to some extent be stored and used as required.
5. Biogas yields are lower due to the dilute nature of substrates and so it also leads to pollution in terms of noise, air and water as a lot of industrial waste remains after the process of decomposition.
6. Biogas can cause obnoxious smells.
7. Recombinant DNA technology and even strain improvement techniques cannot be used to enhance the efficiency of the process.
8.Degasification increases the risk of evaporation of ammonia.
9. Major disadvantage of using biogas in transportation are its limited quantity and then the local production (biogas stations are rarely located in places where they are needed bus depots, etc.).
10.As one uses the organic matter for formation of biogas there remains very little stuff for compost or fertilizer.
11. It can produce very limited quantity of electricity on a global scale.
12. Biogas would encourage deflation of goods prices, due to many producers, and surplus goods availability to the populace and so it will bring about high corruption level, from the top to the lowest level in the public.
Though biogas has many advantages also but still it is not possible for all nations to have an access to it, like those that are islands or desert countries. For these nations have limited land for food production and so will have shortage of necessary raw materials, from crash crops, needed for making biogas. For then these nations will be denied the necessary means of survival.
