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 plantThis 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.
