Safety tip: ground the barrel, since static charges can accumulate on the plastic of the barrel and then you reduce possibility of unwanted combustion. Also, I prefer to use the term methane instead of biogas. Great build!
Thank you Valentina. Here in Australia. Like how simple and compact your design is. I also watched another youtuber that makes $$$ selling the liquid fertiliser. So easy and simple, i will make your design. :-) Take Care Donervan
I like that the size of this thing is quite small. With a few modifications to the design it would fit under the floor of a motor-home so that you can live in the motor-home, flush the toilet, dispose of organic food waste, and even add extra waste from the environment such as leaves to get a constant gas supply for cooking and heating or even to run a generator. The fertilizer and broken-down solids waste it produces can be extracted and used for growing food or sold to farmers or just keen gardeners who want high quality nutrient rich fertilizer and fresh soil for their garden.
Hi Valentina, How is the gas production going now? What about the fertiliser that comes out of your digester, is it black and oder free or not? Thanks for taking the time to put this video together, Brett
Thanks for the effort. While the list is presumably accurate, the photo shot is too far from what is being done. Which parts are going onto the unit and in which order for production? What is being mixed with the cow dung? Is it water? Too quiet almost shy. What is being grated on the spiral grinder and why?
Hi Valentina, I just saw your moovie. Its very instructive. I am going to bild the similar one. One thing which I dont understand is why the feeding pipe is such long, If am not mistaken it almost reach the bottom of barel. Would it not be a problem to feed the substrate afterwards ? Thank you very much. Greetings from Poland. Tomasz
hello! you want the new 'food' to mix a little with the old, and not to have it laying on the top. because you are not opening the barrel to stir it, the long tube, kind of does this..
Valentina, How does the gas fill the tire tube with pressure? You must have a one-way check valve somewhere? Maybe between the top of tank and the tube? Thank you very much for your video!
Hello, thanks a lot for the information. I instantly rushed off and built one using swine droppings. It did generate gas alright but 2 weeks has gone by and the gas still wouldn't burn. Im getting disappointed. What could I be doing wrong?
I will try and do this. This is related to my PhD topic. Thanks for uploading this video. I will use the data l get from this to calibrate my mathematical model
Hello Valentina, this is fascinating! When your gas goes into the tyre tube what kind of pressure do you get and how long could you cook for using the gas in the tube. So the tyre tube is the permanent storage facility with a tap off to the stove/cooker? How long do you keep adding to the digester before having to empty it or drain some of the waste out? I am going to try and replicate your design and see how it works. Danke schon!
Hi Rob. Great that you want to try out the design! If you are in Berlin, you can have this one, as I m not using it at the moment. Yes, the tyre is the gas storage. About emptying some out, It really depends. It will take you one month for gas to start producing after you fill it up once at the beginning with cow manure. Then, i would wait one more month so that the pathogens are killed. after that, you can start emptying some of the digested manure from the bottom and start adding bio-waste from the top, regularly, every week. Good luck!
Hi Valentina! Thanks for the kind offer but I live in Johannesburg. Had I known about you I would have visited when I was in Berlin in July. Did your digester really create enough methane that was really usable? I want to build an off-grid house near Kruger National Park. I see that you are also into rocket stoves which will also be one of my next projects. It is all so very fascinating - and fun. Hopefully if I get something working you can come visit. You have a year start
Rob Fowler Hi Rob, to be honest, I never really managed to produce usable gas so far. I had done the experiment end of August and just right when the gas started producing it got already cold in Berlin in September and the process froze. I know somebody with a similar system and he said he is able to cook with it once a week. so, it does not produce as much in this scale. However, i think its a good scale to start experimenting before you go to something bigger.
amazing, but why u putoff the cap of the container if u already make a Chimney or tunnel for putting the cow dung, and also later on u put from that too, why is it so, i did't get that,
You can add sugar or brewer's yeast (to accelerate the fermentation), and use human waste too (poo), but after that you can't use the mass for fertilize the soil where you cultivate "edible fruits", but is good for flowers.
Chlorine can be removed using a variety of methods. One method is simply leaving the water out for the chlorine to evaporate off for a long period of time.
Hello I had a home made biogas plant. It was able to produce some gas which qas non-flammable. I tried all but was unble to light up my stove with biogas even once. Could you please help me to know my mistake. I want to restart the project. Thanks
@@petes2559 however there are many ways it can be introduced such as compost and yoghurt mixed together so if this person is trying to do research, they’re going to stumble across confusing information
I've been researching biogas for some time now and have never heard of methane spontaneously combusting at any gas:air mixture except in a compressed gas situation. (A paper entitled 'Spontaneous Ignition of Pressurized Releases of Hydrogen and Natural Gas into Air' published by Frederick L. Dryer, Marcos Chaos, Zhenwei Zhao, Jeffrey N. Stein, Jeffrey Y. Alpert, and Christopher J. Homer - Mechanical and Aerospace Engineering, Princeton University) Swamp gasses (or marsh gasses) have been known to combust, however that gas is a combination of methane, hydrogen sulfide and carbon dioxide. The theory for their combustion is that some swamp microorganisms may release diphosphane, which ignites at room temperature, and when it reaches the surface it ignites the swamp gas. Since I'm planning a methane digester, I would be very interested in learning about the possibility of spontaneous combustion. If you happen to have any links that you could share with information, I would greatly appreciate it. Thanks in advance.
Hi, no unfortunately I didn't go that deep into theory. In this case, the methane gas is being compressed by putting it on a car tire and adding some weight on top, when you burn it.. But this is practical. Please upload a video if you built a methane digester!
However the explosion rated compresses are very expensive and the gas does not compress the best. It would probably be worth buying a large gas bladder or bag which will do the same as the tube but could be the size of a mattress.
Hey nice video! I live in Berlin too:D And I want to maybe fit one digester at the back of my truck. From what I read on the internet I thing you get a better productivity of gas if you put stuff that haven't already been digested like cow shit. Cause in a way the job has already been partially done in the cow/animal digestive system. Putting grass or peel of fruits will increase the efficiency. 3 years later did you manage to have good results? How about the smell? Cause I'm scared that having such installation right next to my house might not be a good idea if it smells too much :S Tschuss!
hi Samuel, indeed. I think you only need to start the system with cow manure and then feed it with the things you say. Cow manure, since it has been already digested, has already the good microorganisms you need. I am not using mine at the moment, so if you want to have it for your truck, I could borrow it to you..
hi ths is sai.i make a same type digester 20 days back in my home now its produce the gas but its not flameble(ignite) why?.i allready release the gas compleatly 2 times.what can i do now plz give suggestion.thanq
Hi Sai, first thing to check id what you have fed the digester with. Did you started with cow manure? Cow manure helps to create all the right methane-producing bacteria. Another idea could be that there might be not enough pressure. You can add some weight, such as bricks on top of your car tire, to create more pressure. Related to that is what kind of burner you added in the end of your hose. If you connect it to a normal camping gas cooker, it will most likely not work. You have to connect it to one that is modified for biogas digesters, so, the holes are bigger and therefore more gas is able to come out. That is because we can't reproduce industrial like pressure, such as in the gas cans you buy from the market. Please let me know how it goes!
Madam, I have invested some big amount, to make that plant, at our location it had costed me 4500rs to buy the required material today half of the construction has finished, I want to know can I be able to use it to home purpose efficiently, please replay mam, thanks
+David Mariano yes, you can connect the outlet to a gas stove and use the produced biogas to cook! however, you will need a special gas stove for biogas, with bigger holes, because the gas coming out of this digester has lower pressure. You can find one online, or find some other tutorial of how to modify a normal gas stove..
It depends because you could build a semi greenhouse like enclosure for it that will keep the heat in it for awhile where it’s a lot colder than if you have put a heater in it but it’s much more consistent and that can actually be better
+Khoir Muhammad once it gets going and it has a stable production, I had calculated that you could cook a full meal 1-2 a week with it. I f you use it for smaller things, like coffee or so, it will be of course for more times. I never reached that state actually, since winter arrived in Berlin and everything froze..
Safety tip: ground the barrel, since static charges can accumulate on the plastic of the barrel and then you reduce possibility of unwanted combustion. Also, I prefer to use the term methane instead of biogas. Great build!
The gas is more than just methane as it is impure grounding the barrel can make it act as a capacitor with some types of plastic
Thank you Valentina. Here in Australia. Like how simple and compact your design is. I also watched another youtuber that makes $$$ selling the liquid fertiliser. So easy and simple, i will make your design. :-) Take Care Donervan
Hey could you link that video I'd like to combine both
your project biogas digester...... it's mple and useful. I will made biogas digester . Thank you I saw your video from Java - Indonesia.
Hi Erik, thanx! very proud to be presented at the University in Guatemala. Love your experiments as well!

The fertilizer and broken-down solids waste it produces can be extracted and used for growing food or sold to farmers or just keen gardeners who want high quality nutrient rich fertilizer and fresh soil for their garden.
This is very unsafe as grounding becomes quite hard
Valentina, you did a great job. I like your efforts and I will do it on a small scale at my home. Make more videos...
Great video very informative video
Wonderful. Very straight forward. Very clear and easy to follow. Thanks for sharing.

Gostei do seu biodigestor. Parabéns
amazing, but why u putoff the cap of the container if u already make a Chimney or tunnel for putting the cow dung, and also later on u put from that too, why is it so, i did't get that,
Thanks ¡¡¡¡ have a great day
This was so informative
have you added waste food at last? please tell me what you have added. i'll be gratefull
You can add sugar or brewer's yeast (to accelerate the fermentation), and use human waste too (poo), but after that you can't use the mass for fertilize the soil where you cultivate "edible fruits", but is good for flowers.
brewer's yeast would produce CO2, this process needs methane producing bacteria, so it is neccessary to use cow dung.
Thank you for taking the time to post this.
Hi Valentina ,hast du die Bezeichnungen der Teile auf deutsch.Ich will versuchen das gleiche zu bauen
hello, I would like to ask. do you need to remove the TR C1 short inside the tire's valve? thanks
Hi how did you fit your hose to the tyre valve please
Whats the pressure, volume, volumetric flow rate, tube size, production rate and consumption rate?
The number 10 what valve did you use
Hello... I am from indonesia, i like your video
Parabéns, muito boa sua explicação e o seu projeto.
Lütfen söyler misiniz içine son kattığınız şey nedir? (What do you ply please can you tell in the end ?)
Is it important to use rainwater rather than mains as the chlorine and other additives may inhibit bacterial growth?
Chlorine can be removed using a variety of methods. One method is simply leaving the water out for the chlorine to evaporate off for a long period of time.
Hi! Do you have to feed it again with cow manure or just kitchen waste or both?
There is an element of adding rocket needs, but you could add both if you want or one as long as it’s providing the things that are needed
Hello
I had a home made biogas plant. It was able to produce some gas which qas non-flammable. I tried all but was unble to light up my stove with biogas even once.

Methane Gas Spontaneously Combusts with a 70 / 30 air to gas mixture so how do yo prevent explosion at start up? And when you feed it ??

Hello..why do you use the glass jar with water..i didn't understand..Thank you in advance.
Hi. The glass jar is a kind of a protection. In case that the flame goes back into the tube, then it will be extinguished in the water..
Will be able to compress the gas using a compressor to a cylinder for later use?
However the explosion rated compresses are very expensive and the gas does not compress the best. It would probably be worth buying a large gas bladder or bag which will do the same as the tube but could be the size of a mattress.
Nice video, but need to get more details for how to get the biogas after 4 weeks

Hello Valentina
If my digester is 1m height, in which height should I drill for excess water (fertilizer) hose?
I believe at about 30 cm.
@@valkarga thanks.
I've already drilled it at about 20cm
do you need tomake any change of the inner tube before getting gas in? as there is a valve stem for the pressure
thanks
Yes you have to remove the core valve of the inner tube for gas to enter

You'll also require a constant heat source or a sub tropical climate .

Whats the pressure, volume, volumetric flow rate, tube size, production rate and consumption rate?
This depends on entirely on your system as there are different ways of doing things to change the pressure volume and flow
