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.
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
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:)
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?
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.
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?
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 😎
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!
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.
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!
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.
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.
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?
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 $$$
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?
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.
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?
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.
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.
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
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.
@@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?
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?
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👍
@@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?
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.
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
