Hi there, I am Sahas chitlange, aging 14, from India. here is my homemade cheap and easy to build mini Biogas plant. It burns for approx. 20-30 mins on a bunsen burner. you can add anything from your kitchen waste ( Exept Onion peels and eggshells). In 12 hours the Gas is ready for use. It is very easy and cost effective to build (only 2-3 dollars) and gives many useful products.

the end products of this system are:
1) Methane : (Can be used as a fuel)
2) Slurry     : (the spent slurry is exellent manure)

The main components oof this system are:

1)  Inlet pipe
2) digester tank
3) gas holder tank
4) slurry outlet pipe
5) gas outlet pipe

Pls leave a comment

Step 1: Chose the Correct Container

You will have to chose a correct size container which will act as a digester tank. My one is liters tank. I got it from scrap.
<p>Amazing share ! Must do and feedback </p>
But can we use a 2 litre bottle as the digester tank and balloon s as biogas collecter??? Please reply
Hi sahas. ths is sai i need u r help bro .i make a same type digester 20 days back in my home.now its produce the gas but its not flameble(ignite) i can't understand plz help me.my mail id: lynin.sairam@gmail.com
<p>Biogas contains a varying ratio of Co2 which prevent the ignition of the methane and this ration can be removed by passing the gas through limewater but I recommed Monoethanolamine because it is more efficient but little bit expensive </p><p>and also there is hydrogen sulfide whch is believed to be harmful for machines and it can also dissolve in any basic solution mentioned above.</p>
<p>if anyone could email me an instructional video or the further explanation on the procedure that would be amazing! also how long does it take to create a flammable gas? I am doing this for a school science fair and need more detailed instructions. thanks, my email is christensenga@carbonschools.org</p>
Hello there guys and earth savers. Im starting to build one. My question is, after filling the digester with initial mixture, how many days will i wait until it will create a flamable gas? Secondly how much mixture should i add everyday after the initial gas production to continue the methane production if my tank is 100liter capacity ? Thrirdly im using quail dung, will this work? Thankyou. <br>renier_basilio@yahoo.com
HI, <br>i have a doubt.<br>for the digester tank,<br>can we use a five liter bottle?<br>I'm asking just for school project.<br>
<p>hello sir the digester tank which you are showing in picture is which size? i mean 20 ltr,30ltr or 50 ltr.for it we need cow dunk.but i don't have cow dunk.first time i can manage but i live in city area.every time it is not available so what to do </p>
<p>I tried making biogas plant but unable to generate methane. How first time digester tank pushed to start working?</p>
<p>2 or 3 dollars to make? The cost of a used barrel with a perfect seal? Here about a $100. Then the pipe and fittings, another $50 or $80. Also different glues work with different plastics, you need to source the right kind especially if you are trying to glue dissimilar plastics. I am looking for practical ideas for a developing country, and a barrel like the one used here is almost impossible to find even if someone can afford it</p>
Thin hose , fittings . and Silicone Sealant <br>was the total Purchase cost $20 Us dollars .<br>PVC pipes replaced by cut plastic bottles .extended with plastic bag<br><br>Very low-cost Materials , is all about ... Money is in short supply .<br>I live in Australia always helping to improve lives in Africa .. .<br>
<p>Hi Rick,</p><p>That sounds interesting, I am trying to visualize how you extend the bottles with bags, and join everything together. Do you have some pictures or a video? I am trying to make things from waste plastic, but now am having a problem with so called biodegradable plastic. I don't know what it degrades into, probably small pieces of plastic. Even some PET bottles are made from biodegradable preforms, and are not identified as such. The way I know the bags are biodegradable is in a couple of weeks they rip. Sometimes I don't know which way to jump. </p><p>What other projects are you working on?</p>
<p>Last month Kampala pipe water was cut of .for 4 days .</p><p>Pipe water is very unsafe to drink from the tap .</p><p>This system give them all the 100% Pure water they need ..5litrs per day .they don't have to buy drinking water anymore .</p><p>Now they have replaced the green leaves with a bucket of bad water ,and get perfect pure drinkable water 100% Pure from Sun distilled water .</p>
<p>Most of thick plastic ,of industrial deliverie's is recyclable , not biodegradable Extra strong garbage bags are suitable .this plastic can be sealed and make into any type of bags using a hot Iron between sheets of paper ,the edge can be folded for extra seal . A small amount of silicone seal will do a perfect job ..</p>
<p>HI ..You can replace the barrell</p><p>a hole on the ground ,,, use strong plastic bag instead of plastic barrel ...work same .. Or a plastic bag contained inside strong box . soo the bag wont split ..</p>
<p>Hi Rick, I have seen things like that, even a trench with a long poly tube instead of a bag, but the developing country I am in has a limited selection of affordable materials. I managed to get some used 1,000 Liter plastic tanks with a valve at the bottom and a tight fitting cap so hopefully we can make something practical for about a $100. I don't understand why he says it cost $2 to $3 unless he got confused by the conversion from their currency. Don't you have problems with mice and rats chewing on them? I have seen them chew the insulation off live electrical wires and bucket lids.</p><p>Are you familiar with using charcoal in composting toilets and with animal bedding? If not, look up biochar. When we get set up we will do a study about the effects of charcoal on gas production, I can't find any info about that</p>
<p>Those plastic Barrels are very expensive in Uganda , out of reach for many people </p><p>We have build several using this method .</p><p>Bur we replaced the barrel ,with a hole on the ground ,and a strong plastic bag .</p><p>it has large capacity and produce more gas .... And the top of bag act as a gas storage tank ..</p>
I like u sar u r project plz give that information send to my email address<br>rajashe9535@gmail.com<br> full details sto and light connection plz plz sar
<p>It looks excellent, but step 8 is missing. I hope this works for a friend in Uganda.</p>
<p>I was young at that time. Click, click, publish.... By mistake left it...</p><p>Thanks </p>
<p>Hello i'm Mr Bukky i like your work.....please i want you to give me full details of this project....thanks</p>
How exactly could I help you please?<br>You want what Information?<br>Sahas
<p>hello sahas, this is srinidhi from bangalore. Ccan u plsss send me the copy of ur work to my e-mail id??. my dessertation work is on Biomethanation.</p><p>E-mail id: srinidhi68@gmail.com</p><p>or</p><p>parasharsrinidhi@gmail.com</p>
Bro can you send me a copy maximusfisher79@gmail.com
<p>hello dear. i am Ben from Nigeria. i will like to teach my collegues and friends this method to generate biogas from kitchen waste and animal dung. I will appreciate if I can get more detailed instruction manual on how to make this home made Biogas if possible with video .</p><p>Much appreciated</p><p>My email addressess idayodele@gmail.com<br></p>
<p>I really like this project I've been looking to do something like this for a while </p>
<p>nice you done , encorage your friends to do like you and save environment </p>
Good day! This is amazing! Can you please email your procedure to Kaneisha.rutherford@gmail.com
Please send me the procedure at topslee342@Gmail. Com
<p> i found the cost to be a little off i admire your ingenuity in tool improvisations (hot rod in place of a hole saw) and just building the system in general i am impressesd bravo </p>
<p>excellent work sir can you please mail this procedure to my gamil vragavender@gmail.com</p>
<p>Sir please send me detail how to make Bio Gas plant at below email- pradeepend@yahoo.co.in ; ph 9944445009</p>
<p>the last picture confuses me, why the paint bucket is &quot;floating&quot;. i belive that it must be well atachet and sealed inside the tank. i mean, i believe the tank must be completly sealed, except by inlet pipe, outlet pipe and the vale. if the gas holder thank is floating over the slurry, how much gas it can contain and how much gas scape from digester tank?</p><p>Last question, why do you put that bricks over the gas holder tank?</p><p>sincerely i hope you can answer. i am very interested in this proyect, but need more information and alternatives to use the cow dung. i live in the middle of the city and can't get it.</p><p>thanks for your attention</p>
<p>nice work . please can you send me the instraction by emai to Abdelali.bousta1995@gmail.com .</p>
<p>well done</p>
<p>Does this need emptying from time to time? </p>
<p>How far above does the waste pipe have to be from the contents inside? If I just use the containers lid does this pipe need to be closed to avoid gas escaping through it? </p>
<p>Dear Sir,</p><p>I have no basic idea about dairy farm, But I am planning to open<br>a cattle farm with 10 cows. Kindly<br>let me know, What are other way to earn the money such as generating power<br>and bio gas for supplying to neighbor.</p><p>Muthukrishnan.</p><p>Kr.muthu2@gmail.com</p>
<p>hie bro, my name is Tarirai from Zimbabwe i like the innovation my brother . can you help how can i use your idea suppose i want to use the home sower as a the digester. and how can i connect gas holder to the sower in the event that i need to use for domestic purposes . You may email me at tmwoyowatidhi@gmail.com thank you very much domes domesti</p>
<p>hello my name is Bosco from Uganda, what i didn't understand is the gas holding container is place with open top? or with a cover?</p>
<p>What are good &amp; effective alternative house waste if I have no access to cow dung (and it smells, doesn't it?) since we live in city. I like you simple system. Keep up the good work as this will greatly change the way we generate green energy cheaply everywhere with little investment. </p>
hello dear. i am Garba Matthew Torkuma from Nigeria. i will like to teach village women around me this technology so as to help reduce deforestation since it is really rampart here. can you please send me a more detailed instruction manual on how to make this home made Biodigester please note possible ways to make it more effective and long lasting. thank you.<br>my email addressess are :1. garbamatthew@garbamatthew.com (2) sonofdesun01@yahoo.com.<br>i really appreciate what you are doing.. thank you and remain blessed.
<p>My brother have you started yours? its a great innovation here.</p>
I am working on that... I will be back:).
<p>very Interesting . </p><p>gathering my materials to construct mine in Nigeria </p>
Sir Please talk about the temperature and pH value recorded. Also i need more details on the gas holder design cause I'm a bit confused. My email yusufalhassan@ymail.com . Thank you sir
<p>Hey <a href="https://www.instructables.com/member/Chitlange+Sahas/" rel="nofollow">Chitlange Sahas</a></p><p>Dear can you tell me one thing. I am interested in making such container for CO2 only. I know I can make C02 by doing Yeast water Sugar reaction. And then I can collect it. Tell me this, I will add water in the reaction container. and then title upside down another container. But does the Reaction container must contain enough water that if collection container goes all the way up and gas still produces what then?? </p><p>Also tell me the Floating container will move left right as well, so how can we fix its position. </p>
<p>I had played around with pulleys with ropes and weights to balance the floating gas container. Some kind of track for it to rise on would be ideal, then you could add weight to pressurize the gas without it flopping around.</p><p>If you're going to make CO2, you might as well make something delicious like beer or wine and use one of these with water to just capture the gas (note the hoses in the picture)... it doesn't have to be the digester or fermenter itself.</p><p>If it goes all the way up, gas escapes. If you're pressurizing it with weights, you may need to remove some water or digestate to prevent it from spilling over the edges.</p><p>Cheers and happy digesting!</p>
