Gobar gar renewable energy
Explain your idea in details:
Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen, primarily consisting of methane and carbon dioxide. In India, it is also known as "Gobar Gas". Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Gobar gad is produced by anaerobic digestion with methanogen or anaerobic organisms, which digest material inside a closed system, or fermentation of biodegradable materials. This closed system is called an anaerobic digester, biodigester or a bioreactor. This energy release allows biogas to be used as a fuel. it can be used for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat. Biogas can be compressed after removal of Carbon dioxide, the same way as natural gas is compressed to CNG, and used to power motor vehicles. In the United Kingdom, for example, biogas is estimated to have the potential to replace around 17% of vehicle fuel. It qualifies for renewable energy subsidies in some parts of the world. Also cleaned and upgraded to natural gas standards, when it becomes bio-methane and considered to be a renewable resource because its production-and-use cycle is continuous, and it generates no net carbon dioxide. As the organic material grows, it is converted and used. It then regrows in a continually repeating cycle. From a carbon perspective, as much carbon dioxide is absorbed from the atmosphere in the growth of the primary bio-resource as is released, when the material is ultimately converted to energy
Expected impact of your idea on sustainable development
Gobar gas can be used for electricity production on sewage works, in a CHP gas engine, where the waste heat from the engine is conveniently used for heating the digester, space heating; water heating and process heating. If compressed, it can replace compressed natural gas for use in vehicles. Gobar gas for home cooking is transferred to the cooking place like kitchen from the digester through a tube. Except electricity, biogas when compared to other fuels produces less pollution while cooking. Need not wait for the heat after ignition. It produces instantly. By product of biogas is used as fertilizer. It helps in producing indoor light. And also for electricity external combustion engine When biogas is combusted externally Stirling motor is heated. It is heated with the help of heat exchanger. On the expansion of gas in the Stirling motor electricity is generated. Since their efficiency is low and are expensive, their use is limited. Internal combustion engine Gas motors, gas turbines and diesel engines are some example. It helps in agriculture as the by product of biogas helps in the production of organic fertilizers.
Plans for implementation and sustainability
The purpose of industrial biogas production is the collection of biomethane, usually for fuel. Industrial biogas is produced either. As landfill gas (LFG), which is produced by the breakdown of biodegradable waste inside a landfill due to chemical reactions and microbes, or As digested gas, produced inside an anaerobic digester. an anaerobic digester that treats farm wastes or energy crops. It can be produced using anaerobic digesters (air-tight tanks with different configurations). These plants can be fed with energy crops such as maize silage or biodegradable wastes including sewage sludge and food waste. During the process, the micro-organisms transform biomass waste into biogas (mainly methane and carbon dioxide) and digestate. Higher quantities of gas can be produced when the wastewater is co-digested with other residuals from the dairy industry, sugar industry, or brewery industry. For example, while mixing 90% of wastewater from beer factory with 10% cow whey, the production of gas was increased by 2.5 times compared to the biogas produced by wastewater from the brewery only. High levels of methane are produced when manure is stored under anaerobic conditions. During storage and when manure has been applied to the land, nitrous oxide is also produced as a byproduct of the denitrification process. Using of biogas helps in reducing pollution and makes eco-friendly environment. It reduces global warming. It is a cheap and affordable technology. Also, it can be used as transportation fuel.
I am now 17 years old, doing my college in Electrical Engineering. I was born in a village of Nagpur and had both my primary and secondary education there. As I was educated in villages, I understand the situation of the rural students what they suffer from, what are their problems. They do not have access to good teachers specially for mathematics and science. Most of the students are very afraid of mathematical problems and cram mathematical solutions. Unlike urban students, they even do not have access to lots of competitions for self-evaluation. In 2007, while I realized that I have to do something for my villages. Therefore, I formed a small team with my school friends.I love to the self taught and to modified some innovation or recreate old innovation that impulse me even more and to devise alternative solution start from smallest to create project with greater social impact than even development I am able to collaborate with all society across different cultural, country, language I am intrastate in helping community to promote healthy living and improving aspect of life standard
