Bio gas(renewable energy) system remains already an important system in rural India. And now it is coming out as a lifesaving for the city population. Furthermore, it also become more popular among the cities. For example, it becomes the substitute for firewood, dung, agricultural residue, petrol, diesel and electricity. Biogas system provides organic waste residue after anaerobic digestion of the waste.
This is an excellent manure and therefore, substitute of chemical fertilizers. It also functions as waste throw out system. And further this can prevent environmental pollution and spread of harmful diseases.
REDUCTION OF CHRONIC DISEASES DUE TO THIS RENEWABLE ENERGY
Apart from this, Bio gas is a powerful source of renewable energy and clean free source of energy. This reduces the general chronic disease related with the indoor burning of biomass. It may be respiratory infection, lungs , bronchitis, lungs cancer, asthma and many other arterial diseases.
INCREASING RATE OF LPG
Biogas becoming popular day by days and replacing LPG due to its increasing price.
ROLE OF RENEWABLE ENERGY IN CITIES
Bio gas is playing an important role in cities too. This is because of increase in pollution, decrease in air quality and irregular climatic change.
IMPROVEMENT IN AIR QUALITY
Air quality improves when bio gas converted to biomethane liquified and filled in cylinders fitted in motor vehicles. It replaces diesel with less polluting fuel. Investment in bio gas plant can help in producing renewable energy.
Bio gas uses itself can reduce the climatic change.
There the complex organic waste mixed with hydrolytic bacteria to change into organic acid. And further it breaks
into Formate. In turn it converts
into Acetate using Homo Acetogenic
bacteria. And further with the help of
methanogens converted into methane.
Home-grown biogas plants change domesticated animals refuse and dung into biogas and slurry. This technology is possible for small-holders with livestock producing 50 kg manure per day. This is same of about 6 pigs or 3 cows. This manure collected and combine it with water. And this is fed it into the plant. Toilets are often connected.
OTHER CONDITIONS
Besides the above, temperature affects the fermentation process. With an optimum at 36 C° the technology mainly applies for those living during a (sub) tropical climate. This makes the technology for little holders in developing countries often suitable. In fact, energy is a main part of modern society. It may function one among the foremost leading marks of socio-economic development.
The maximum amount as there are developments in technology. In fact, some three billion people, mainly within the rural areas of developing countries, still use for energy needs for cooking through customary methods. And this is by using biomass tech. For examples are firewood, crop deposits and creature waste in rough traditional ovens.
Domestic biogas technology in many parts of the World is the proven technology. Furthermore, many Asian countries in this region have programes on domestic biogas, like India, Sri Lanka, Nepal ,etc. We all should renewable source of energy.
