Time	Narration
00:03	Is this a common scene in your household?
00:07	Is this how food is cooked every single day in your home?
00:14	Do you wish you could reduce the drudgery of collecting firewood for cooking?
00:23	Would you trade your traditional firewood cooking for this?
00:28	This could be the setup of your kitchen from now onwards, forever.
00:35	Want to find out how? Watch this video!
00:40	Welcome to the Spoken Tutorial on Biogas and its benefits.
00:47	In this tutorial, we will learn about biogas, how it is produced and its uses.
00:57	We will also learn in brief about the biogas plant.
01:03	So, what is biogas? Biogas is a gaseous fuel. It is a product of fermentation of remains of the bio-degradable organic waste.
01:20	The main component of biogas is Methane.
01:26	Biogas can be produced easily and for free, by using a biogas plant. This is what a family type biogas plant looks like.
01:42	Some of the benefits of using a biogas plant are listed as:
01:49	* Installation of family type biogas plants in villages helps protect natural resources.
02:01	* It also provides standard basic amenities to the rural population.
02:10	* Biogas plants help reduce the drudgery of women, in collecting fuel wood from long distances.
02:22	* It also helps in minimizing health hazards during cooking in smoky kitchens.
02:31	Once constructed, the lifespan of a biogas plant is approximately 25 years.
02:41	Biogas plants are easy to use and the maintenance is quite simple.
02:47	The raw materials used to produce biogas are- waste generated in the kitchen, like- vegetable and fruit peels, leftover food items, eggshells, bones etc.
03:08	* Domestic wet waste like the water used for cleaning floors, spoilt milk or tea etc.
03:21	* Plant materials like fallen leaves, flowers, stems etc.
03:29	We can also use waste generated on farms, solid waste of cattle, liquid waste of cattle and the solid and liquid sewage waste that goes into the toilets.
03:46	Let us briefly learn how biogas is generated.
03:52	This is the diagram of the family type Biogas plant.
03:59	What you see here is the mixing tank where we put the raw material.
04:07	The inlet pipe carries this raw material inside the Biogas plant.
04:15	And this is the digester tank where the biogas is generated due to fermentation of raw material.
04:24	It is also called as the compost tank. Here is the output valve from where the biogas is ejected out of the plant.
04:38	There is also an outlet pipe for the slurry.
04:44	The slurry collects in the slurry tank and can be taken into the fields, to be used as manure.
04:53	So, how much of space is required to build a family type biogas plant?
05:01	Typically, to build a family type biogas plant, we require 12 ft by 8 ft of land.
05:11	Now we will discuss about the budget for building a Biogas plant.
05:18	The minimum cost for building a biogas plant is from Rs 20,000 to Rs 23,000/-. This amount may however vary from place to place.
05:36	A few banks provide loans to build a biogas plant.
05:43	The government also provides subsidies on completion of biogas plant.
05:50	The government gives extra subsidies for the tribal areas through Zilla parishad and Gram Panchayat.
06:02	Additional subsidy of Rupees 1200 is given if the biogas plant input is connected to the toilet.
06:14	The details of the cost of building the biogas plant,
06:20	how to apply for the loan in a bank and the subsidy will be covered in other tutorials, in the same series.
06:32	Now let's see the benefits of biogas.
06:38	The use of biogas and biogas plant are extremely beneficial. Biogas is an eco-friendly, non-polluting, renewable source of energy.
06:51	Biogas is a very good replacement for LPG, kerosene and firewood.
06:59	It can be obtained free of cost, once the biogas plant is built.
07:07	Biogas plant helps in human and cattle waste management, agricultural waste management as well as kitchen and domestic waste management.
07:20	It also decreases soil and water pollution and plays a critical role in preventive healthcare.
07:32	Let us look at some of the time-saving benefits.
07:36	By using biogas, we can save a lot of time which is otherwise spent in collecting firewood.
07:46	Use of biogas is also very good for health as no smoke is produced.
07:54	Also, it is very hygienic as there is no charcoal deposition on the walls of the cooking area. This usually occurs when firewood is used.
08:08	Next, we will learn what are the other by-products of the biogas plant.
08:15	We can get nutrient-rich natural manure from the slurry generated by the biogas plant.
08:25	The wet slurry waste can be directly used as manure in the fields.
08:33	The slurry can also be dried and powdered and stored for use, later in the fields.
08:43	The dried slurry powder can be sold as natural manure to farmers, fruit orchard owners and nurseries in the big cities.
08:56	This manure can also be used to make organic fertilizers with the help of earthworms.
09:06	This is easily done with a technique known as vermicomposting.
09:12	Using this organic fertilizer in the fields will save a lot of money for the farmers.
09:22	And, this organic fertilizer can once again be sold and become a source of income for the family.
09:32	Generally, biogas generated by a family type biogas plant is used for cooking.
09:43	It can also be used to heat large quantities of water for bathing and other purposes.
09:54	Some rural small-scale industries use biogas to supply heat in various processes.
10:04	Let’s now watch a testimonial from a biogas user family.
10:10	Hello, my name is Subhash Balachandra Madgowkar and this is my wife Shubdha.
10:21	There are four members in my family and we also have three cattle.
10:28	Earlier we used to go very far to the forest to collect firewood.
10:35	Sometimes we also used to purchase firewood. Now we have been using biogas for past 10 years.
10:47	Ever since using biogas, we don’t have to go to far off places to collect firewood. We don’t have to purchase firewood.
10:59	We don’t have to inhale smoke while cooking and the kitchen looks neat and tidy.
11:08	Biogas is easy to use and is sufficient for cooking for my entire family.
11:16	Let us summarize. In this tutorial we learnt about biogas, how it is produced and its uses.
11:28	We also learnt about the biogas plant, cost of building a biogas plant and benefits of using biogas.
11:42	This video was created by Spoken tutorial Project with inputs from Rural-ICT team, IIT Bombay.
