Making a biogas digester // free gas at home // PART I
HTML-код
- Опубликовано: 15 авг 2024
- Making free gas at home with a biogas digester using household food waste. The first part of my series trying out a small biogas digester, setting up the digester so it is ready to produce gas. This could be a great addition to any household, especially if you are off-grid or in an area where propane is expensive or difficult to get.
There are quite a few videos out there about biogas digesters. This looks like a great way to produce gas for cooking and even to generate power. Before I jump in and make a large out capable of producing enough gas to supply a home I start with a prototype to learn the details.
If you want to make one yourself you will need:
1 x 220lt (55 gallon) drum
2 x 3" uniseal
1 x 2.4m 63mm PVC Pipe (PN10)
PVC cement
2 x 63mm end cap
2 x 63mm 2" Male BSP PVC Threaded Adaptor
1 x 63mm 90 degree PVC Elbow
1 x 63mm 90 degree PVC Tee
8 x 5/16" Uniseal
3 x 3 Ltr Clear plastic jar
2m x 5mm plastic pipe
I hope following me doing the building and making the mistakes means you won't have to if you come to make one yourself.

I love the trial and error parts included. It lets people know that they are going to run into challenges. So many time I have found myself in the same situation. "Okay how do I make this happen" then you just climbed up on top and made it happen lol. Love it. Very nicely done! new subscriber gained.
It might be helpful for anyone looking to recreate this to add a list of the parts needed in the description, sort of like you did in the second video. Amazing job putting this together, it’s fun to see your trial and errors with it 😆
Great idea I'll do that! I'm think to do a final cut how to video at the end as a kind of summary of the parts, what I learn from my trials and errors haha. Cheers!
He couldn't have done it in the second video this is part one 😎
When using that type of hole saw, it is possible to enlarge the hole by fitting the original size hole saw, inside the larger hole saw. This will help, centre the larger hole saw, and stop it sliding about.
I like your project, I will learn about simple biogas system. Thank you.
Thank you! Glad you liked it. Cheers
@@GetMeOffGrid_ I will duplicate your models biogas. Thank you.
well done! interesting to see other peoples and the variations they come up with.
Thanks very much. Its definitely a work in progress but interesting to play around. Hopefully when the weather is better here I can get back to experimenting with it. Have you made one? Cheers
Any proses filter fill
My guy you are an amazing someone thanks 👍 for this initiative
Much appreciated
Heat is what these need. I'm in the process of making a compost hot water to heat my ibc tote style biogas digester.
Great idea! What kind of temperatures will that be able to get it up too?
thanks now my left ear know but my right ear dosent XD
maybe one can tell the other...
Good video
Glad you enjoyed
Interesting video thank you fro posting it.
Glad you enjoyed it
Fantastic! Love it.
Thank you Judith! :-)
@@GetMeOffGrid_ where is the 2nd video ??

Hey, I like the video! Have you done part 2 yet?
Hey AJ. Yes here it is ruclips.net/video/yfpx0CZazN4/видео.html I hope you enjoy it. Cheers
I'want to know the fittings for the biogas system works better for axmple tee,tubes, clumps,gas stove
Uniseal have a drill sizing chart; I had the same challenge. Good job.
Hi, will dog poo work? I'm currently working towards off grid and have 14 dogs.. I hope they can help towards their up keep! 😉 Ta. 🙂
Hi. Dog poo is tricky one as it can have some nasty bacteria in, so using the outputs as fertilizers would be a no go. Apart from that dog poo could be used as a supplement but it couldn't be the main base of the digester that would still need to be ruminants manure.
good job
Thanks!
2 questions, 1) why 2 gas outlets? 2) have you a link to follow up vid?
1) Nothing complex; there were two holes... 2) I think you've found it :-)
@@GetMeOffGrid_ Thanks for reply, I’ve set up a basic mini system using what I found in skips etc, it’s a 5 gallon container connected via some fish tank rubber tubing. Attached directly to an old Pushbike Innertube, just to prove to myself that I can make BioGas, and to give me confidence to chuck out my old Electric cooker. To I have room for a Digester about the same size as the one in your vid. The Innertube has inflated so a small amount of BioGas is being produced, that’s without any heat and being in the coldest room in my flat. By what I’ve done so far is seems it isn’t necessary to use Cow Dung as most people do. As I only want to use Plant matter, and perhaps some of my own shit. What do u think?
Please what is the name of the drilling machine you used in creating the holes on the barrel..
they are hole saws, attachments you put on a drill
how many barrel to supply family of 4 in every cooking?
I am not sure. It would depend on what you are feeding it and how much gas you use to cook with. If you want to supply a family I would suggest at least 1000ltrs of capacity.
Plss, why do u have 3 holes 🕳 on the Water 💦 scrubber, can u explain much further plss 🙏🏾🙏🏾🙏🏾🙏🏾
It is because I can have two outlets from the digester into the scrubber.
Like your videos
Thanks Victor!
For the big pipe are there all now to the bottom of the tank
The two pipes that go through the uniseals go to the bottom of the tank
Thank you for the video
You're welcome
I feel like I'm being lazy just asking here, but I had assumed that other plant matter (not kitchen waste), such as grass clippings, weeds, etc ("green" compost material, not "brown" compost material) would be fine to add to a biodigester - is this the case?
You can add it but it is what would be classed as "low energy" feed so you'd need to make sure you were still feeding it with kitchen waste to keep it going. You could also supplement with extra cow manure.
grass and other "green" compost that i think you are talking about, contains a great deal of lignin, which is the main component of leaves, ligning cannot be breakdown easily by anaerobic bacteria, and a pretreatmentshould be added for these kind of "green compost" in order to get a considerable amount of methane.
Nice
Could you add the size and length of the pipes that go in the barrel.
Hi Joe. The pipe is 2" diameter. The in-pipe can be just a bit longer than the height of the barrel, so around 1m (double check that as some barrels are slightly different heights). With the out-pipe you will want to put an T-piece so that can also be 1m, then add the T-piece, on the vertical coming from the T-piece you can add any height. I have left mine without as that means I can see into the T-piece and monitor whats going on. I hope that helps.
Hi Joe. I've added a materials list to the description. I hope that also help. Cheers
Hi Tom
Is it possible to substitute cat litter with beach sand?
Hi Calvin, You would need to substitute something that is able to absorb moisture well. Dry sand would not be ideal. Charcoal, would work.
@@GetMeOffGrid_ wow thanks dude, does it have to be activated charcoal?
@@calvinsalim2375 From what I can tell it doesn't matter. Activated Charcoal could remove other impurities in the gas, but in this case it is only used because it will have an extremely low moisture content
The gas produce from this drum is enough for household cooking? Thanks for the reply
Might you turn up the volume please I'm old and can't hear good Thank you
Hi Joe. I have had comments about the volume, sorry about that. I think it varies depending on the type of device you are on. I have changed the software I edit with since this video so hopefully this is not an issue on newer videos.
Cant wait for part 2 I'm kind of thinking of making one!
Cheers! Its a process but an interesting one especially in temperate areas where air temperature is the biggest issue to overcome. Where in the world are you?
@@GetMeOffGrid_ I'm From the state of Maine in the usa the best thing about the digester is that basically you get fuel and liquid fertilizer I'm probably gonna make it a summer project
@@thegaminginferno1287 Yes exactly! Double-bubble as we would say. I'm going to do some trials with using the fertilizer for hydroponics once I get it up and running well
@@GetMeOffGrid_ I would love to see video logs of your trials and ideas that would be so cool to watch!
Let me know if there is anything else you would like to see. I am game to give any idea a go!
Nice video . It would be good if you the sound was better we can't hear you.
Hi Rita. Thanks very much. Yeah, sorry about the sound this was the first video I ever made to put up on YT so I wasn't really sure what I was doing with that side of things. All a learning process and hopefully you can see how they have been improving since then. Cheers
Also please what is the name of those black-round rubbers you fixed into the holes you drilled on the barrel ?
Uniseals

Ask geknowing questions
Please take more care to capture the plastic waste from these projects. We don't need any more microplastics in the environment.
I totally agree, I'll take more care in the future
How long does it take to produce enough gas to run the generator for an hour?
Not sure. I haven't been able to produce that much gas yet. It will depend on the feed you are using, the temperature of the digester. Lots of things will influence that.
Nice video. Great work man.
Question:. What is better, 1 big system like 10tonner bio digester or
10 smaller system of 1 tonner container? Appreciate you very well thought of response. Thank you! GBU!
Farm produces 15 tonner chicken dung.
Hi. I would say one bigger system, although I don't have much experience with bigger systems. This means the material will be in the digester for longer. Economies of scale means building it would be less expensive than multiple smaller ones
@@GetMeOffGrid_ thanks. I thought so too. But 2 minds are better than 1. I agree 1 big system is cheaper to build.
@@GetMeOffGrid_ can you please help me with the description of material components used to make canister
I know people in developing countries use methane from septic systems. Do you think that is dangerous. I mean regarding pathogens and such. I suppose methane is methane. Guess the ick factor makes it's weird. Seems like a waste of good gas, if it can be used. Any thoughts ?
Yeah, I think it can work. Only issue here is people use lots of chemicals that I am sure would have a negative effect on good bacteria. There is a health issue as well, there can be some nasty bacteria is human waste so it would need to be managed carefully.
@@GetMeOffGrid_ yea I've seen those biogas kits that have a toilet and a stove. Weird but I guess it works. I suppose the bacteria can't travel in the gas, and if they did they would be incinerated.
Dzień dobry wszystko fajnie wytłumaczone. Mam pytanie odnośnie spalanego biogazu, jakiego koloru jest u Pana płomień? Ciekawi mnie to pod tym względem że u mnie płomień ma niebieski kolor przy niskiej ilości tworzenia biogazu. Pozdrowienia z Polski.
A good flame will be blue.
@@GetMeOffGrid_ czy uważa Pan że w filmach gdzie jest kolor czerwony / pomarańczowy plomienia to oszustwo?
@@GetMeOffGrid_ że tak zapytam, ile litrów biogazu udaje się Panu pozyskać z tej beczki 200 litrów na 24h? Z moich nie dokładnych wyliczeń wynika ze dla mieszanki 2l serwatki, 1,5l gnoju krowiego i do 0,5l wody którą dolewałem, nie mieszając lub nie często mieszając, dla temperatur 35-39 stopnia C utrzymanej około 12h to 1l nie filtrowanego biogazu (po 3 dniach 3l zbiornik po soku), dla temperatur 42-45 stopnia C (ogrzewanie mogło trwać dłużej z 14-16h) poniżej 2l z tego samego substratu na dzień.
@@abiogaz I haven't been able to do any tests like you have done. Really nice work! I will also be feeding mine with food straps not just slurry so it would be a bit different. Seems like you are doing some great work.
bardzo dziękuję, w planach mam większy bioreaktor (20l) ogrzewany elektrycznie, chce zobaczyć czy będzie to opłacalne.
Pamieta Pan może jakie kleje i uszczelniacze były używane w filmach i czy się sprawdziły?
WHAT TESTING CAN WE DO SIR? TO TEST THE EFFICIENCY OF THE SET-UP?
Efficiently of conversion of inputs to biogas??
In the set-up sir, the gas comes out is pure methane or there is a mixture small amount of co2 and h2s?
@@CarloLRamas You can get gas sensors to access the quality. You can try this: ruclips.net/video/oYuDIjgNXvQ/видео.html
Next time install the outlet pipe without the rubber attached to the barrel put on the pipe, once it's all the way to the bottom of the barrel slide the rubber outside the pipe. Work it round to fit you can use a blow dry to heat the rubber to fit well. (My two cent)
Okay great thanks! :-)
Is making biogas like making a alcohol mash type mixture? 🤔
Yes, pretty much. The smaller the substrate the easier it will be digested, either into gas or alcohol.
how can I get in touch with you?

You will need to be more specific than that. What do you want help with?
I go to pure biogas
Which chemical substances you have used for using biogas please tell me in comment section because I am not understand your english language
No chemicals. Just cow manure, food scraps and water.
which substance used purifying of biogas
Can you use yeast to make biofuel?
Not sure to be honest. I guess so, ethanol can be used as a biofuel.
You can't call this part one and when you've already done this entire video series before making this video 🤣
Sure
