A large drum could be an IBC tank, or closed drums. If you are using drums with lids, make sure it is perfectly sealed when completed I am using 220 Liter sealed drum 4 inch diameter PVC pipe height should be based on the height of the drum you are using 2 inch Tank nipple 2 inch FTA(female threaded adapter 2 inch ball valve and 1 ft 2 inch pvc pipe 2 inch L joint Half inch brass ball valve 2 nos Brass t joint haf inch Threaded brass hose connector 8 nose hose clamps half inch A truck tube with tube valve removed Hose as per length. Epoxy putty to seal eveything

That explanation is honest enough to discuss that 5 mins is the life of one bag of air

I don"t Know if you check your comments but if you do I would like to offer this: The Japanese I think it is have been building and using a village size version of these for many years and have perfected the design. As you are using barrels I think you could use many of their design features. 1 If you will add a 45 or 90 degree fitting to the bottom of your feed tube aimed along the edge of your barrel it will provide you with a stirring action when you are loading it this will speed up the fermentation time. 2 add another barrel or more to act as gas holding tanks as they hold higher pressures, if you want you might add a in line pressure gauge to see what you total volume of gas is. In the Japanese design they use all types of slurry materials, Their systems are large concrete flattened ball tanks that are placed in the center of a village size community. All the houses and barns have feed pipes that run into the ball at a 45 degree angle along the outer edge so as to provide the stirring action I mentioned above. another feature they have is a large pound built over top of the ball. This serves a couple things, I protects against gas leaking and spountanioucly combusting, As methane can do when it is mixed with air in large quantities to fast ( very dangerous ) And it also provides for raising tallopia fish or catfish ( as these fish do not require moving water for oxagynation to live ) for food. with their systems they use a top unload man hole. but with you side extraction pipe I would suggest this barry the set of barrels into the side of a hill, with a man made pound on top with water level above tanks but below feeder tube. allow the run off line to go down hill to a point where you can collect it for use as fertilizer. ( the reason the Japanese can use human waist in their systems is because it is built from concrete and can build up inner temperatures of over 180 degrees so it kills harmful bacteria that will harm humans. By doing these things I think you will increase the amount of gas and possibly the rate at which it is produced, for sure the pressure at which it can be stored safely. Yes I've been studying these systems for many years now. Sorry for bad spelling Dislexia is a real bother lol

I wish every other diy videos were made like this. Thumbs up for an all round well made video

You can paint the barrel black to make it absorb more heat in the winter. In the summer, a pool of water submerging the base to wick away excess heat.

I like the honesty. Making videos to share knowledge, not to get fame.

Thank you. I just enjoy to watch smart engineering and craftsmanship. Even though I won't build any of these any time soon this is the best video on this subject I've seen so far. You explaining things makes it an appealing thing and setup to try (once I get my own house outside of the city).

This is a really well laid out video and a joy to watch. I have a digester built from an IBC Tote and am versed in the assembly and operation, however I can always learn more. I really like how you've presented all of this without the usual false promises of unrealistic gas production for a small biodigester. Thank you for taking the time to make this video.

Trust me Bro this is the one of the best video about building a biodigester, everything is well explained, keep it up Bro 👍

thank you for being honest about the capacity of the tube

Good Job, Man! I second that the outflow tube can be higher on the barrel to increase the digesting volume which would increase possible gas production. The bacteria used doesn't need airspace, other than for the collection reservoir which could be bigger and have a removable weight of some kind that could be put on the reservoir to increase the gas pressure when you want to use it. People often pass the bio gas through a tube full of steel wool to scrub the NOx out before sending it to the reservoir ... The bacteria does need to be kept warm to work best, at least 75°F, If I'm remembering correctly... Hoping people find this on a community level as one of the solutions to the "energy crises" ... God bless!

Thank you so much for this wonderful exhibition. You've given us clear insights and what to expect. I can't thank you enough.

This is by far the best DIY video I've ever seen. I Subbed asap when you mentioned its cons. I wish DIY channels are these transparent and detailed like you than filling us false hope

the feedback at the end was really good, it educates us about the actual application of the project. Thank you

It was really an amazing video and the way u did this at home and also informed the cons of the setup was very informative. Thank you

Such a well made video! You explained everything so well and I love your design. Thank you so much!

This is the most detailed and truthful video I have watched! Thank you for being honest in telling the truth about your experiment which was about the "flashback arrestor" you failed/forgot to connect as well as the capacity of one barrel. These are important information that a person like me who wants to start an off-the-grid community really needs to know. I wish to meet you in person!

This is amazing! I would love to learn more about this and also I will be making a quail cage by using your design. Thank you. Please keep posting videos. I enjoy watching you interesting content.

This is one of the simplest and easiest to understand videos I've seen on bio gas digesters. Well done on keeping it simple and easy to understand. Even my dumbass brother could understand this.

I really appreciate the honesty of your video. A lot of channels who do diy stuff like this related biogas will not say how long such a set up would last and how unreliable it is.

You did a absolutely wonderful job explaining... Thank you so much sir.

Well done. I enjoyed watching your video. I am moving to the Philippines next year and I built a biodigester for my futue wife and her family already. They are familiar with how it works but never owned one before. My soon to be father in law is a farmer and does very well with the amount of land they own. I wish you and your family a good life my friend.

Your video just blew my mind with ideas! Thank you for sharing!

When the Algo works perfectly. Found this chanel just now, really nice and articulate video. Much appreciated.

You're one of talented teachers I've come across. You've the theory and the know-how. This 1st clip has pushed me to subscribe to your channel. An asset to humanity. Check you later and stay good.

Simple, well made, and practical. Thank you for this video my friend.

Thank you for the video. It is the most clearly presented one I have viewed. Now I feel I am ready to start.

You are an excellent teacher. Thank you. One of the best biogas videos I have found.

Fantastic honest opinion and demonstrated the flaws, you've earned my sub. How about a barrel within a barrel as the reservoir? think of a glass held upside down inside a fish tank and you release the gas into the glass, the pressure of the water will give you a decent pressure to release it. Paul

🙂 Hi, your video is well made and very interesting. Remember to add a good backflash arrester to decrease the risk of explosion. If you try raising the height of the slurry pipe you could fit more in the reactor. Then it may produce more gas a little sooner. You may find the bacteria works better at a different temperature. If its cold it may wok better in a sunny position. If too hot maybe a shady position. I think, if the rector temperature was around 24c it would work very well. I would not let it get to hot though as it may effect the bacteria that produces the gas. Just trying to help 👍

Very nice of you, to show us! THANK´s for uploading the video! THUMBS UP!!!

Thank you very much. I made it months ago and I faced those problems and just didn't know why. Thanks

As an environment engineer, i would suggest you to add a mixer and add some organic digestate to improve microbial activity and increase methane formation...... And if possible add a gas compressor to compress the gas and improve the outflow......

Great explanation with the black board. Wonderful setup sir!

very informative and genuine video which includes all possible shortfalls encounter during bio gas construction. truly suggested add-on like backfire arrester and 5 min run time which provides a good lead for the person like me. hats off to you for making such valuable video.

Dude, you are doing a great job, very informative video. Keep it up.

Hey mate, Jeff from New Zealand. Loved this video! Well explained and showing the limitations is great, many over rate what you can do. I have a friend who uses and air bed as his reservoir and lays a piece of plywood over it to get more pressure when cooking.

Well done, clear and concise. Thanks for not dragging it out.

I find your presentation very easy to go through it step by step with a good finish outcome. Clear to understand. Thanks for sharing brother. Greetings from Solomon Islands

Hello my friend, Another interesting and different idea. That's nice for savings. In our country, biogas is produced in some places. It is produced especially in some of the farms. You showed your project in detail. Result: Successful. Congratulations. see you buddy. All the best

The septic tank itself is the biggest and most consistent biogas plant already present in everybody's house 😂😂😂. People just never noticed it ever.

You my friend havemade me understand how this works. I will be trying this out soon.

Your video is very great and very inspiring! I'm very sure your family and community are very proud of you! Awesome explanation! awesome design too! thank you very much for sharing this

Hi. A really good project. I have a very small upgradation idea. You could make a gas scrubber to really purify the output gas. You will need three jars. Fill 1 st with water, 2nd with a drying agent like cat litter, and 3rd with steel wool. They will decrease the amount of waste gases in the output. Then you could use your lpg burner very easily. Oh and yes, you need a big gas reservoir to use it for 30 min. But in this way, this little tube could be used for more time.

Nice video. Very clearly explained. Think you need to make scrubber from steelwool and pvc pipe that will prevent possibility of explosion

Very complete and comprehensive. Thank you.

Thank you for being honest in your presentation.

What a timing I was just looking for diy bio gas plant and where were you how come youtube didn't recommended your videos till now Very well made and explained Looking forward to upgrades made to it

Always wanted to make something like this. Great work

beautiful explained in the blackboard, I always wondered why they leave the top of the pipe open in the piping system used at our home.

Thank you very much for the wonderful lesson. Am in Uganda learning from you. You're a very good Teacher. I am going to make my own biogas

I think a pressure gauge shall be installed on top to warn how much gas is still available in the tank.

Nice video, if you want to increase the output you can try to build one from an ibc tank, its 1000 liters. At that size you start with 100 kilos of manure and food waste in about 900 liters of water. When it starts producing gas you can feed it with 40 liters of water and in that 4 kilos of manure/food waste daily. You may get an hour or two worth of cooking with a single burner. Who would think that handling manure was fun!

This design is brillant!!! Very informative👏👏👏

Im glad i found your channel, great layout of the video really presentable

A pioneer in compost heat and methane was Jean Pain. He cooked his 'waste' and produced much methane. He used hot compost for heating (air and water) provided hot water and methane.

Just watched your video try using a air mattress to store the gas ⛽ 😀 with a couple of sand bags as weights get to of the barrels on the roof is a good place for it more heat means more gas there's a Australian KZfaq who does same and transfers the gas to a old gas bottle hope this helps 👍

Well explained Sir. I'm just in the verge of making one for my Farm. 👍👍 Thanks a lot.

Thank you for such a wonderful nd open presentation. I have been yearning for abioGas videos like this for long.

It would be great if you list down the materials needed.

Nice set up over all. Have you experimented with different ratios of waste and dung, perhaps using other types of dung from different animals? As soon as you lit it I thought about how there was no flash arrestor or some sort of pressure release valve at the top of the barrel. Anything that builds up pressure needs to have an emergency pressure release. Also perhaps include a pressure gauge to see how much pressure is being built up at a given time.

You are great. That is practical. I want to make one like that. Thank you for your time and energy you put into your video.

This was excelently done. Wow

You did a great job. My question are: 1, is it possible for the gas to escape through the inlet PVC pipe? 2, does the size of the inlet pipe matter when constructing bio gas?

You give us a great information regarding biogas

The best explanation i have ever seen. Thank you

Maybe 3 very large rubber inner tubes from giant mining trucks could sit around the blue barrel stacked on top of each other with a heavy donut ring of bricks to add pressure to the tubes? Great video! You’re a real survivor and lateral thinker, the world needs more people like you.

Watched from Bangladesh,your presentation was very clear,easy and understandable. Thanks❤

Start the seconds and get to the point is what I like. I Like it

Hands down your vid is the best I have come across. Thank you kind sir.

Thanks bro!....your video is very explicit....double thumbs up 😊

Thanks for making this It's the best video on this subject that I've ever seen. I'm definitely building this now, and if it works satisfactorily, I'll make several more, and get larger storage tubes as well.

Your video is so informative and it was really very helpful to me. Thanks a lot.

Thank you for this video. It's the best with simple detailed instructions. 👍👍

Amazing video. Just the info i needed.

Cool and simple easy to follow ,not too technical.

THANK YOU for your Honest Opinion and Excellent Effort 👌. Good job Brother 👏

Good job! Thank you for the information. This will help a great deal.

Thanks for being real and honest man...

You just earned a subcriber, brother. Keep it coming. Thanks !

Very well explained,,,🎉🎉🎉good job

Appreciate your efforts and Thanks for sharing the video.

Thank you for the very clear explanation. Very hard to find online...

Hey thanks for being really honest!

Love ur way of explanation 😁😁 Nice Old school....may be ur a teacher in some school...but ur doing great service through this platform...

Very cool! Thanks for sharing!

Thanks, you Are such a good teacher

Amazing man. Keep creating content. ❤️

thank you sir for your simple and meaningful content

Very interesting. My digester is in Switzerland where I have to heat ist up to around 30 deg. With my 1000 l. tank and the input of a few kilos of kitchen waste with the help of my neighbours I can do most of the regular cooking in our household.

Only you can do such great things..amazing...keep going 👏👏

Thank you for sharing knowledge.

Finally and honest review on this topic.

Hey man, great video. Very informative and interesting.

Very clearly explained, so good 👍

I just loved it. Thank you so much....🙏🙏🌿

your video and explanations are wonderful

Really nice video . U have great skills both videos and craftsmanship

Thx for sharing the process 🙏

It would be useful to put a stop valve on your tyres so that you can fill them, and remove them for later use. Having a system of three or four of these (or more) digesters cycling for use would make them more practical for daily use.
