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 were 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 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 lets 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	Sometime 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 plantCost 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.
