| 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-
|
| 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. |
