How to start a biodigester and making gas - Biogas basics

[@ddnsolution]

My brother, I truly appreciate the quality of this video. Low tech straight to the point with content. I know as you continue on with your content creating journey and provide your community with free knowledge but I wanted to let you know that I appreciate the quality of the content you are providing and keep up the good work.

[@jeremyhoglo9346]

Ideas for videos: Size for biodigester ratio for production ..... obliviously it depends on how well you maintain; Uses for biodigester: heater, stove, Fertilizer, etc..... but also this relates to the size you build because heater or stove probably takes a good size for everyday use and need waste to feed the monster

[@lugo2214]

Excellent needed information!!!

[@jacobschenkel1010]

Excellent content mate! Greetings from Shanghai. Especially appreciate the advice about checking for good gas before feeding. In the dozen or so build/start up vids I watched no one mentioned this but I’ll be taking your advice:)

[@harrylatva2274]

Lots of Thanks from sunny Sweden:)) A most excellent explanation "Why no methane until about 20 days from first start-cow-manure"

[@pepsiisgood101]

Keep sending it! You always post very informative videos. I love it!

[@IrishEagIe]

I'm making a biogas generator right now so this is great

[@michaelgregory4666]

I have another question. Since it has taken me so long to get my biodigester started, is it possible that the manure has depleted the rumen and is "dead?" I've tried adding more manure to the old and mixing Rid X enzyme-based drain cleaner with it... 3 more weeks... no results.

[@manulemos219]

Thanks a lot for sharing your knowledge. Just a question. Based on your design, how do you actually access the solid bi-product to use as a fertilizer?

[@sustainablebunnybiogas]

Thanks for this great video, I want you to describe how to start a bio-digester using effluent from a old digester.

[@OkAtEverything-ProAtNothing]

I used old digester material to start my 2 when I moved them from the greenhouse to the shed, just add old material, fill up with water, make sure temp is good, add more manure if you can, wait 3 weeks or till burnable gas, then good to go.

[@pierreretief]

Hey man, thanks for the great info, going to build a small prototype this week. The temperatures you mention, I am assuming that the is temperature of the slurry, and not the gas? Also, do the solids build up over time, and need to be cleaned out? Lastly, how often should you add water/food scraps? Thanks again!

[@fransandreas9724]

I like this channel👍, never give up bosqu

[@oseghaleengineer2135]

Nice video there with detailed explanations! I would like to know. Should the inlet pipe of a digester be covered or should remain open after pouring in the slurry into it?

[@OkAtEverything-ProAtNothing]

Much of a muchness I guess, a cover would certainly stop flies, quite often find maggots in the feed pipe, but they too go down with the next feed and get turned into gas too 😎

Je voudrais juste témoigner de mon expérience avec le digesteur que j'ai créé en m'inspirant du tien . J'ai utilisé du fumier de vache sortie de l'écurie depuis 15 jours avec la paille, que j'ai retiré en remplissant des poubelles avec moitié fumier et moitié eau, et dans laquelle j'ai plongé un malaxeur à bétons. La paille c'est accrochée au malaxeur et j'ai renouvelé l'opération jusqu'à ce qu'il n'y ai plus de paille. C'est assez long ! J'ai remplis la cuve ibc à 500 litres et chauffé à 32 degré C. Au bout de 7 jours, du gaz a commencé à sortir par le bulleur et le 10eme jour, le gaz s'enflamait. Depuis ce jour je l'alimente quotidiennement, nous sommes au jour 24 et je produis 7m3 de biogaz par 24h. Je vais maintenant filtrer le CO2 car je ne veux pas, ou le moins possible comprimer le biogaz. C'est selon moi trop energivor. Jeff, dans le sud de la France.

[@pauloantunes8826]

Great videos! Two questions, how much gas can you produce with one IBC in your conditions? and how do you store it?

[@ndlovukazi5977]

Very informative from S.A

[@justinyelevielbayire8595]

Great information Bro, what do I need to do when my digester goes sour? Thanks

[@Joelwilly57]

How long does it take for the system to start making the gas ?

[@micahgrover8158]

Can add store bought enszymes to manure during startup?

[@Meleeman011]

i was thinking of pasteurizing my waste for ecological safety and adding kitchen scraps to it, i'll buy the enzymes for ecological safety and to comply with regulations, seems i could just pasteurize my urine, and add the enzymes

[@fuba44]

Can you start one with horse 🐎 droppings?

[@bushengineeringcareventure717]

What can I do to make the methane gas flammable and ignite

[@Termiic]

Excellent tutorial! Can i use horse manure?

[@ryanblackwell4896]

Little off subject but have you ever thought about making bio gas from wood? You could fill your air mattress in less than a day.

[@underdog5004]

What do you think about adding basic stuff to raise ph in the reactor? Like calcium (bi)carbonate, potassium (bi)carbonate?

[@OkAtEverything-ProAtNothing]

I did try this when the digester went sour my first time around, unfortunately it was too far gone and had to start again, but yes if you monitor your pH levels you can alter it using bicarb, and the cheapest I found was a 20kg bag from a pet produce store, buying from the supermarket is $$$

[@pierreretief]

With regards to the temperatures, what would happen in a situation where it is cold at night, say 10 deg C but hot during the day, say 40deg C (inside it will probably be 50 or 60), what stage would it be in, does it sort of avergae out the temperature due to the slurry acting as thermal mass?

[@dominicroberge3852]

Hi and thanks for sharing your knowledge. I have start 3 biodigester and they become sour because ive have put to much food.. do you have a feeding ratio or how much food i should put every time in my 1000 liters tanks? And those the PRAL chart (acid-Alk chart) must be use for the feeding type to not turn sour too fast? Thanks again.

[@asiesprodz1696]

Hi Mate, how you doing? I have a quick question. My neighboor has two horses and I wonder if I could start my biodigester and feed it with horse manure. I just realise that horses and not proper ruminant as are cows, sheeps and goats so not sure about it. Thanks a lot for your answer mate!

[@featherweightfarm]

Would it be feasible to cannibalise some of the methane to heat the ibc or would that become a diminishing returns kind of scenario? Great video. Thanks for sharing your knowledge. I'm down in Tassy, so I am trying to think of ways to make it work on a very cool climate without having to feed enormous amounts of energy into keeping it viable.

[@OkAtEverything-ProAtNothing]

You certainly can do this, I have a biogas hot water unit, when temps get lower you can heat some water and add in, just have to watch though, the bacteria does not like sudden temp changes.

[@redgum78]

Hey dude, any thoughts on burying the digester to maintain temp rather than have to heat it? Most ground temps are above 15 degrees, I imagine it would would help with system stability too?

[@awuduzakari7352]

please I've tried a biogas but is not coming

[@broswilli]

Great video. Please can we use poultry manure as activator?

[@joewamsley8004]

I've heard you could.

[@kanddfamilyfarm]

Hey mate, new to your channel and I'm soaking up the biogas info. Love that it's all in Australian so I don't need a translator. Will this work for straight human manure only?

[@OkAtEverything-ProAtNothing]

From my research you can run it from our waste as it still has caloric value, but you still need to start up a digester properly ie cow manure or ruman species, once it’s running, I don’t see why not.

[@kanddfamilyfarm]

@@OkAtEverything-ProAtNothing thanks for the quick response. Not sure I'm overly keen on cleaning thermometers over the Tassie winter though.

[@aicram62]

If you have a lower level of liquid will you have space for more gas?

[@Kevin-oz9fw]

What else can you use instead of fresh farm animal manure to make a starter slurry? I am worried about dog or human waists and bad pathogens.

[@ManoloElCerdo]

There are some bacteria for sell, and they're not that expensive either

[@FedericoAllegretti]

some says pigs are great methane producers? could we use their poo like activators?

[@ManoloElCerdo]

Will dog manure do? I have no access to cow/sheep/goat manure

[@replicantpedals6085]

Not really

[@manulemos219]

There's a lady in Peru that uses rabbit manure.

[@DinoPasic]

Can i use my septic tank for producing biogas? I guess i need to avoid chemicals in it? Thanks

[@adreenryan2901]

What about pig slurry or is that a different gas.

[@icariusian]

I started my biogas, floating drum type. My feed is chicken droppings and this is what I put in first and the drum has never risen.

[@OkAtEverything-ProAtNothing]

Sorry for the late reply, I hope your digester has started producing gas, it is recommended using dung from animals with rumens to start up, as it will need the necessary bacteria to start.

[@icariusian]

@@OkAtEverything-ProAtNothing Thank you. I will restart everything.

[@markgeurts258]

Thanks for all the good information about your experiences. I have a question about the amount of manure that I want to use to 'start' my biodigester (1000L IBC container). Can I also use a small amount of this Horse/Cow manure? Sometimes I see some fresh droppings on the road. And I don't know if this will be sufficiënt for the bacteria to produce flammable gas in such a large container of water? If have enough food scrappings tho.. But 200liter of manure wil be a problem :p Best Regards, Mark

[@OkAtEverything-ProAtNothing]

Hi mark, is it possible to save some up for a while? But where possible and as gross as it sounds, fresh sloppy manure is easier to work with, my first digester I just put an add on FB asking for cow manure, people were very nice and keen to let me on their paddocks with a shovel....worth a try? Second time round I had a mate that bought a farm.

[@markgeurts258]

@@OkAtEverything-ProAtNothing Thanks, that's a good tip! And if i don't find enough, maybe i can adition it with my own poop.. (Just to get the thing going) Or will this not work beqause of the different bacteria?

[@OkAtEverything-ProAtNothing]

Yer mate different bacteria, you can supplement with enzyme drain cleaner possiblt

[@underdog5004]

Im so early to this video, its still dominated by acidophiles

[@fashiontuberswati070789]

how can boost gas production

[@michaelgregory4666]

I have a 1000L IBC tote. I filled it with 900L with 50/50 cow manure and water. after three weeks I had no gas because I had air leaks so I fixed them and waited for another 3 weeks and still no gas. What else do I need to look for?

[@OkAtEverything-ProAtNothing]

Hmm, even the smallest air leak somewhere will stop bubbling, but a 50/50 mix sounds a bit much? I think my slurry was maybe 100L cow dung and water then fill the rest with water, also check your temps👍

[@michaelgregory4666]

@@OkAtEverything-ProAtNothing I live in Montana. It rarely gets up to 95F degrees. Do I need to get a heater? What size do I need to heat 1000L? How did you install your heater?

[@michaelnewcombe5531]

Can you add human waste during the activation period?

[@OkAtEverything-ProAtNothing]

Hey mate, I would wait until you definitely have burnable gas just in case, after that I wouldn’t see a problem.

[@calebmarkv6671]

Hi, Would alpacas poo work well?

[@fishmut]

cant see why not as long as it is fresh and not dried out, what ever manure you can find i would use it. even human manure if your game lol .

[@Kiyarose3999]

We can just as easily use Human ‘waste’ instead couldn’t we?, we digest via fermentation!.

[@origins4774]

pretty extreme animal noises

[@usanasealine3404]

How long does it take to refill the biodigester ( dung+ water)
