I have been making biogas for over 20 years using trash from the local supermarkets and horse stalls. Have made far more than I can use for cooking so to vent it out I run a generator at times. The leftover solids and liquids grow some great veggies! As for Cuban oregano that stuff grows wild here.
Nice! We are approaching our first year of making it. We love the gas and the fertilizer. We have a variety of Cuban Oregano that we found growing wild here as well. Tastes delicious!
@@ColoradicalMike I wish more people did this, it would go a long way to reducing energy needs and help stop sewage leaks into our waterways. The fertilizer is another bonus! My only drawback is with my biogas digester being underground it takes a bit of work to clean it out,
Agreed. It would be nice if more people had them. Especially in rural areas without sewers since it is basically a septic tank that captures the methane rather than let it vent into the atmosphere.
You can, but it takes some serious pressure and/or really cold temps to do it. The methane also needs to be purified since biogas is a mixture of methane, CO2, and air.
Thanks for sharing this informative video. As soon as I heard the “pitirre” bird I hit subscribe. Growing up in Ponce, I heard many. You chose the most beautiful place to relocate to. I wish you the best on your adventure!
Great video......question! Can u connect the gas line to an actual stove with several burners and maybe can it handle a table top stove or can it only handle that one stove?
Thank you! You can connect it to a stove/range that is made to use natural gas though you may have a noticeable decrease in the individual flames for each burner if you cook with multiple burners at the same time.
It would have to be accessories designed for natural gas. Propane accessories use different line pressure and orifices so the fuel air ratio would be different and possibly not ignite if switched to natural gas.
Great video! I noticed that you hadn't tied down the guylines on the top of the digester to anything. Was that on purpose or was it an oversight? Thanks again for posting this.
Is it possible to empty the bag into let’s say gaß containers ? End then have the methan stored inside the gaßcontainiers until u need it ? Or is there going to be some kind of pressure problem ?
Yes it's possible. We haven't done it yet but we have seen a few videos on TH-cam where people have used air compressors to put the methane into propane tanks.
The manual says no because that kind of stuff breaks down too slowly and could potentially back up the system. If you are familiar with septic tanks the same rules apply as to what can and cannot be put in.
I wonder if you can store more methane in a separate tank. I think I heard you say when the bag on top fills up the excess is Exhausted out? Would be great to catch the excess as well!
You can. It is possible to compress it, with an air compressor, into a propane tank or something similar. The excess gas escaping is a result of the bag's internal pressure pushing back on the system to the point where no more gas is able to enter the bag. Unfortunately, as far as I know yet, the only way to prevent that is to increase the storage volume by adding another gas bag or to use the gas, and thus release the pressure, before that starts to happen.
Some people in tienes of Venezuela and Brazil even recycled old refrigerador motores to compress gas into empty butane or other gas bottles! But Its dangeroud, of course...even though..must be very satisfactory to keep ocassional overproduction pressured and stored in those metal bottles
I love at how pleased you looked at making biogas from your poop💩..this is part of the reason why I'm here I wandered if there was septic tanks that also produced biogas....👍🤘
Hola from here ~~~ wondering about quantities of your organic matter you're feeding the system ~~~ I have worked with large methane digestors but with swine slurry, which produces incredible amounts of methane. How long after you started inputting material, that it started cranking enough methane? great info....
It took about a month to get going but is very active now. I feed it daily with humanure and with food waste from the kitchen about every other day. About 4 liters and 10 liters, respectively. It takes roughly 0.5-2 days to get a full bag depending on how much we feed it. Manure is definitely the best for rapid methane production.
@@ColoradicalMike Great info to know. Any possibility we could visit? whatsapp, skype, google chat? Your set up is exactly what we are looking for to help rural communities generate biogas for cooking @ a family home level ~~~ propane has become very hard to come by in Venezuela, and Rural areas are clearing a lot of land for fire wood for cooking that's problem #3 ~ crazy. Any who, we have the 1st unit in route to a friend of mine that is going to learn how to operate @ home ~ then we'll head to our 1st community to setup a couple of units as a pilot project ~ bio digestors is one of our activities within this watershed... let me know if we can talk. easier than typing hahahaa : )_~~~ cheers
That sounds like a wonderful project! Our home isn't open to the public so we don't have visitors that we're not familiar with but we are open to chat via Whatsapp. We received your email and will be responding soon.
Hey Man, can i put my dogs crap in there? I really need a good solution fir the poop they make... i just bought one. Thanks for the video Atlanta Ga. Homestead!
Though its something that wont fly past the HOA where I live, its very interesting. Let us know how the bag holds up in the Puerto Rico hot and humid climate.
Will do. The one outside seems to be doing well so far. We have another one that's sheltered from the elements so it will be interesting to compare the 2 after a few years.
Hi, I have bought a HomeBiogas in Guanajuato, Mexico; but I didn't put the sandbags into de biodigestor because I had no money in that time, nor now, because I had covid infection; but waht I wanted to use it for was to feed my plants with the outsource liquid, but I wonder: Is the liquid that comes out not full of bacteria which can be dangerous for us to be feed with our organic plants? What do you think?
Yes it is possible that some of the bacteria could harm you if ingested. With that in mind it is still possible to feed your plants and stay safe. We use watering cans to pour the effluent around the base of plants being careful to only wet the soil and not the leaves. For low growing plants like greens it is hard not to get it on the leaves so we thoroughly wash or cook those.
@@ColoradicalMike : You're the best and quicker than Speedy Gonzalez! Thank you very much, indeed. It is my thinking that when I am able back to walk again after covid, I shall be able to buy a big bag with sand so that I can create enough preasure down so it can make the methane to fill the top gasbag and I shall be able to boil the effluent -you've given me actually a new word in my life- and besides, I shall be able to water the soil as pasteurized as possible.
Could you tell (more or less) how many litres of waste mixed with water you need to feed pero day, and /or how many " minutes of cooking do they provide perl litre? Thank you
Hi, while we don't measure it exactly we would estimate that we feed it about 15-20 liters of material (not including the water) per week and we get about 1-2 hours of cooking time per day. The system can be fed much more than that and thus produce more gas but we have found a nice balance and use what we have readily available to feed it.
@@ColoradicalMike Thank you very much. I am thinking of having one but Im.living alone in am urban context and. i wonder I produce soooo little waste that would be able to. Cook 10 minutes a day or less ...i think i would have to roam dog Parks, vegetable markets or something like that to fullfin the minimum
Very interested in this product. I’m about to move off grid and this digester seems fantastic. Do you think it could digest mushroom mycelium? Sawdust? It’s organic matter so I would assume it could
Mycelium fruiting bodies yes, sawdust no. Organic matter high in cellulose like wood and fibrous plant matter takes too long to digest and may back up the system.
Couple questions. Does it have a bad smell. Like are the neighbors going to complain? And does it only work in more warmer climates? We have relatively hard winters where I live.
The smell is like the smell of manure. It's only noticeable when you open it to feed it. The smell dissipates quickly the further you get from it, so unless your neighbors are really close, I don't think they'd notice. For colder climates, it's recommended to put it in a greenhouse to keep the temp up. If it falls too low, your gas production will stop.
The bacteria that produce the methane will go dormant if the temperature drops below 19 degrees Celsius. It would require a heat source at that point. It works best in the tropics where temperatures are warm enough year round.
This is pretty cool! Do you ever have clean it? I've been watching your videos, you guys are doing some amazing and interesting things here in Puerto Rico! Oh, how durable is the bag? Like a animal can't chew or claw a hole in it or anything? We are here in Puerto Rico and have a lot strays come and dig up our compost.
The bag is pretty durable. We have strays and our own kitty too and so far no problems. We also make sure to run them off if they are messing with it. There is maintenance with it like emptying the effluent bucket and feeding it but that's about it. It mostly just sits there.
@@ColoradicalMike We had some stray dogs get in our yard and destroy one of our cacao trees, so that is a concern for us. I am guessing you don't keep it too close to your house? Sorry for all the questions ☺
@@ColoradicalMike I think there are 13 species of Moringa ~ from Asia, Africa, and Madagascar +. I got interest in Moringa while working in American Samoa as a source of protein for human consumption and animal feed. I asked since I found Moringa oleifera in the wild in A. Samoa,, and apparently is also found and used in Western Samoa, and nobody knows how it got there... I think palagy's (white people) brought to the islands, but don't know, as Pacific Islanders navigated between many islands for thousands of years... Found different sources as to the origin of M oleifera one all the way to South Asia , and others as South Africa. It would be interesting to trace it and see if any of the other islands closer to Samoa have them, like Fiji, Tonga, etc... Are you using it to feed any animals? chickens, pigs, etc?
Wouldn't be surprised if it had multiple points of origins. We are only using it to feed us since we only have four trees as of now. We planted it for it's nutritional benefits and use it in almost every meal.
The gas will just vent to atmosphere once the storage bag is full. It just bubbles out of the effluent drain. It's not dangerous as long as you are mindful that it is flammable gas and take appropriate precautions.
I love that you mentioned humanure...i was wondering that! personally I use my urine as a direct fertilizer (10p water to 1p urine) works great....I think this is the next logical step in my self sufficiency. How many hours of gas do you think you get each day? 2-ish? thanks for the info thanks
It IS beautiful, because we have been taught to regard the act of peeing and even more poooing as "making the world dirtier" , instead of what It was, nourishing it. But , of course, via flushing away and sending all to waste water town collector It in fact was .
Yes, you can, though I've heard that it is hard to get a good ratio of uncompressed volume to compressed volume, so not many do it unless you can get high enough pressures to liquify it like how they store propane.
Ive built three digesters . I love making free biogas its amazing. Congrats on your setup.

Not too much since we live in the forested area but one of our dry seasons was really dry and hot a couple of years ago.

Yep, a biogas digester is basically a septic tank that is designed to catch the methane that's produced.
How did you connect the hose from the bag to your kitchen/the gas stove?
We used the stove that came with the system. It's a very simple clamp/hose hookup.
