Step 8:

Completed unit. I have removed the gas pipe, so that the joints will get cured without any stress:

Wait for a day or two before feeding the system, allowing all joints to get cured and become leak-proof.

Initially, cow-dung mixed with water will be fed in to the system, which will start the gas formation process. Subsequently, food waste, decomposable organic material and kitchen waste will be diluted with water and used to feed the system. The gas holder will rise along the guide pipes based on the amount of gas produced. We can add some weight on top of the gas holder to increase the gas pressure. When we feed the system, the excess digested slurry will fall out through the outlet pipe, which can be collected, diluted and used as organic manure.

Initial production of gas will consist of oxygen, methane, carbon di oxide and some other gases and will not burn. These gases can be released to the atmosphere by opening the ball valve at least three / four times.

Subsequent gas will consist of about 70 to 80 percent methane and the rest carbon di oxide, which can be used in a single bio-gas burning stove or a Bunsen burner.

Total cost of this proto-type system is about one thousand Indian Rupees (about 20 dollars)

This is a basic prototype of a Bio-gas system using the food waste, decomposable organic material and kitchen waste to produce gas. An one thousand litre capacity Digestion tank will be sufficient for a small household for daily cooking purpose. The bigger commercial models provide a water seal between the digestion tank and gas holder tank.

You are amazing, i understood this project easily by ur clear steps and appropriate pics. I was finding this system with easy techniques.
thank you...
<p>Hi, </p><p>I am highly <br>interested to try it for domestic use. I live in Colombia. Can you<br> send me more detailed instruction through my email. The email is 20.mauricio@gmail.com. I will really appreciate this. thanks</p>
Please see attached files sent to your mail
Please could you make a video on how it is done step by step.<br>My email is olaidemogaji@gmail.com<br>I am a physics student of the University of Lagos and the University is close to a slum which generates very large amount of waste but no one to tap into such abundance. We complain about lack of power supply but fail to tap into such golden oppourtunity.<br>It would be my utmost pleasure to have this video and carry such ingenious idea to the slum and bring them out of darkness.
I did not make any video. As I work alone in most of my projects, I prefer to take pictures. For taking pictures and videos also I need some assistance, otherwise it may not be possible.
<p>I'm still skeptic about how functioning of slurry outlet. It seems to be fixed a bit too high, does the slurry actually rise up that high, and does a single hole actually help in pushing out all of the waste? </p><p>And second, what's the use of the 64&quot; feeder pvc, when organic waste is being/can be directly poured into the digester tank(which is also easier and hassle free)??? </p>
it is very simple. You can fix the slurry outlet at any height, but the slurry can not be stored more than that height. Digested material float up to the top.and when you add more organic waste, the digested slurry at the top portion of the tank falls out through the outlet pipe.<br><br>Secondly, how can you pour the waste directly in to the digester tank when Gas holder is floating in it ? Do to that you have to remove the gas holder tank and loss all stored gas. You can not pour the waste through the sides
<p>hi mr antoniraj. Very nice instructions. Have a question - how do you feed kitchen waste into this system..what dilution with water do you use to make the feed slurry.</p>
<p>the kitchen waste needs to be pulverized using a blender and diluted with 4 to five times water. The diluted waste is fed through the feed pipe fitted at the center</p>
<p>Good day sir. I came across this project online and I am highly interested to try it for my domestic use. I live in Nigeria. sir can you send me more detailed instruction through my email. the email add is <a href="mailto:akinnat@gmail.com" rel="nofollow">akinnat@gmail.com</a> . I will really appreciate this. thanks</p>

<p>Dear antoniraj</p><p>I'm currently working on a university project regarding home made biogas plants and I'd like to include pictures from this article in my report as an additional example. Would you be so kind to allow me to use your publication and pictures from this website in the report?</p><p>Kind regards,</p><p>Anna </p>
<p>Yes, you can use the picture from this Project</p>
Well done work.GOD bless you always
<p>thank you...</p>
It is so sweet, you folks are so polite and considerate, and also very eager to get involved in a good undertaking. I hope you undetstand that we Americans are sometimes amused, and sometimes frutrated with your use of English. But that is a minor matter, your hearts are so dear.
<p>thank you...</p>
So the tank is just slightly larger than the bottomless &quot;gas holder&quot;. And the open bottom gas holder, more properly called a collector or trap, floats, bottom edges submerged, in the slurry. The guide tube and the close proximity of the sidewalls of the two &quot;cans&quot; (plastic buckets), one within the other, keep the collector/ holder upright and oriented so as to maintain the bottom edges in the fluid, trapping the gas as it rises from the slurry, not escaping under the bottom edges of the collector (floating dome made from a plastic bucket), and out the top of the collector, through the couplers and up the gas &quot;pipe&quot; (i.e. hose, a pipe is ridgid, a hose is flexible, in all technologies). From there it can flow to a burner, or be compressed into a storage cylinder for later use. Noam Chomsky is my hero, as are the people here.
<p>Yes, you are absolutely right. This is a prototype working model constructed for demo purpose only.</p>

I made a comment about lack of detail and the source for the digester tank. I now found the second previous link to your plastic &quot;can&quot; design/version/small digester. In the US this is referred to as a &quot;bucket, and is one of the most common containers in America. Typically, this detailed, well illustrated guide would ne the first link, and then the more general description of the larger dark colored digester unit eould make sense. Seeing the larger description first, I assumed that one was supposed to be the the primer (first, more detailed so as to clarify more brief, later descriptions of altetnative or final/ scaled up versions. I now see the entire picture, thank you. Robert Bowen, Master of Space and Time.<br>bowen5400@yahoo.com

Sir, can u pls elaborate abt step 4, ie what must be the diameter of gas pipe and the dimensions of T-valve and other items required...
The diameters and sizes of gas pipe and other items are same as being used in normal LPG gas stove. You can get these items from hardware vendors selling gas items or from Drip Irrigation accessory shops. They also have crimping tool for attaching items to the gas pipe.
<p>Gud day sir, this is very interesting project. Currently i am working on biogas production using fruits and vegetable waste, please how can you be of help to me in terms of materials and method to use. You can send any useful materials and procedure to my email. ogadom4rill@gmail.com thank you very much. </p>

<p>Hello Sir,</p><p>Its glad to see such a beneficial idea. I am planning to make a feasibility report on how can we produce biogas for a colony of 100 houses using the kitchen waste in an urban area. Can you please help me out if it would work for a colony ?</p><p>Thanks </p>
<p>It will work for a colony. you need to consider collection of waste from all those 100 houses. A bigger fixed dome type Biogas plant is required for waste from a colony. Also, how do you plan to utilize the digested slurry which is good compost for plants</p>
Send me gas making procedure n photos for my home kitchen in small unit deepesh48@gmail.com
What happen sir no reply yet
<p>there was some problem in my system. please see attached files sent to your mail</p>
<p>Sir,in villages ,they make a underground pit of brick and mortar ,to make a biogas plant for feeding only cowdung,this is a fixed dome type,why cant the same setup be used for feeding food waste, decomposable organic material and kitchen waste only,will there be any problem.</p>
There is no problem in feeding kitchen and other organic wastes or even weeds to the fixed dome type Biogas plant. Village people may not be aware of this and they think only cow dung produces biogas.
<p>Dear Antoniou, </p><p>Need details for 500 Ltd of tank email id: rceakgb@gmail.com , also want to know how the gas containing tank be fixed on digester tank such that it is moveable and at the same time airtight. </p>
Please see my other instructable on How to build a medium sized Biogas plant at the following link. Here I have used a 750 liters tank as a Digester and a 500 liters tank as Gas collector. You can use 500 liters and 300 liters tanks respectively for Digester and gas collector. Go through the instructable to see how the gas collector tank is fixed so that it can move up-and-down and also airtight. Feel free to post your comments if you need any clarification...<br><br>http://www.instructables.com/id/Constructing-a-Medium-Sized-Biogas-Plant-Using-Kit/<br>
