Write a note on bio gas plant. Also write advantages of bio gas.
Answers
Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste. When organic matter, such as food scraps and animal waste, break down in an anaerobic environment (an environment absent of oxygen) they release a blend of gases, primarily methane and carbon dioxide. Because this decomposition happens in an anaerobic environment, the process of producing biogas is also known as anaerobic digestion.

Answer:
✍︎Bio gas plant ✍︎
The biogas plant consists of the following parts:-
1) Inlet or charge pit:- for passage of slurry into the digester.
The raw material used is cattle dung, farm refuse, organic waste.
2) Digester:- cylindrical tank which is airtight, above which is present a floating gas holder of metal with an outlet of gas and pit for removal of sludge.
Here the organic wastes get solubilized into simpler substances called monomers (solubilisation).
Monomers change to organic acid by fermenting microbes (acidogenesis).
Organic acid mostly formed is acetic acid.
Methanogens become active and act on components of microbial digestion and form methane gas (methanogenesis).
3) Outlet:- consists of sludge which is used as manure.
The methane gas formed in this process is used for cooking and lighting.
✍︎ Advantages of Biogas✍︎
Biogas is environment friendly and has various applications in cooking, drying, cooling, heating etc. It is used in the production of electricity, methanol and steam.
Biogas can be transferred to the kitchen with the help of a digester through a tube. Biogas, when compared to other fuels, produces less pollution while cooking (with an exception of electric current). Furthermore, the byproducts of biogas can be used as fertilizer. Biogas also helps in producing indoor light.
