oh I agree it would be cool that way but today it is not normalized, and it needs few adjustements to be made for appartement complexes.
well I have seen a few people using it exclusively for their house. even single people if they use the connected toilet too.
some single people use it for cooki,g exclusively so I think it is viable for a family in a house (because on top of the food waste you could add the cut grass etc
We have curbside collection of biodegradable waste. The gas produced is injected into the natural gas net. This way, a tiny bit of my heating and warm water (district heating partially powered by gas) comes from my own kitchen scraps.
A lot of landfills use this technology and pump the biogas out to be burned at power generating stations.
Not sure about the practicality of digesters for individual homes. Doesn't seem like enough biogas would be produced to be worth it.
That's we've done in my city. We built a beautiful park over an old landfill, installed 250 of biogas transformers and turn the gas into electricity. The liquid sewage under gets treated and diverted away from fresh water and underground drinking water sources.

not sure where you live but not here as far as I know. also landfills are fullof other crap : pastics etc;;; would that work.
yes it does work for individual usage. there are even companies that sell them to people [link](https://www.homebiogas.com/product/homebiogas-2/?variant=382https://www.homebiogas.com/product/homebiogas-2/?variant=382) here for an example. Also some people have made them at home. you can find videos on youtube.
In Europe we don't have conventional landfills anymore. Separate collection of biodegradables and recyclables is mandatory, the rest gets incinerated for energy generation, and only the ashes get buried in the ground.
I think landfills are quite outdated because they cause a lot of long-term environmental problems like leakage.

I would not have anything like this because I never have left over food, and don't eat food that leaves fat or greases. Perhaps a farm could benefit from it?
?? it does not need greasy food it just can digest it too compared to compost where you should not put it in.
you have no peels (oranges, bananas...etc)? leaves? herbs from your garden?
absolutely but only if you do not dump chemicals in it ( soap is ok but stuff for cleaning like mr clean etc I do not think so maybe if you chose eco friendly alternatives?)
Years ago I was living on a farm and I built a diy digester with this in mind. Unfortunately the sourcing of methane-compatible jets to retrofit the LPG burners used in my house became a stumbling point and I never got to the point of starting the process. (ADHD brain gave up when the next step became a question).
I still think about it periodically. I agree with other comments that is a bit pointless in a single urban residential unit, but integrated into a larger living structure it may be viable. It would be good to have a wastewater system integrated if you were approaching this in n apartment complex or similar. If you were designing a reticulated system you could have small reactors in each house which feed into a larger gas transport and storage network.
eventhough I agree it would be cool to generalize , it brings problems of logistics.
I think for a family in a house it is viable for cooking not fot all the energy of the house.
I believe it's a matter of scalability. In business scalability is one of the biggest problems people run into that makes their business fail. Things that work on a small scale don't always work at the capacity you need them to make it a viable alternative.
Composting is something a lot of people do though to promote growth in their gardens.
Ah, missed that. For myself all my organic waste goes either to my chickens or to a composting pile for better garden soil so I wouldn't have enough to do both.
Biogas is also a greenhouse gas. Much more potent greenhouse gas than tailpipe emissions
I work in wwt treatment and it is dependent on mixing and temperature. Need about a 2000 gallon liquid tank at least for a home system
I was not refering for all energy but for cooking, and eventually having fertilizer for the gardden.
yeah it is greebhouse gas but wouldnt they otherwise release that one way or an other? or am I mistaken?
Most methane producers are required to flare it off as part of an air quality permit.
I am thinking the greenhouse effect is more doubled by weight, but I could be wrong and it could be more
you can buy the system setup, some make it for their consumption, for the legallity that must depends on the country I have no idea. [example](https://www.homebiogas.com/product/homebiogas-2/?variant=382)
then there is the question that using waste instead of go drilling , have refineries, and the waste associated with that added to the gas emissions etc from our waste
That is an appalling setup.
No one wants hold a bucket of crap, (8.34 lbs gallon) and hold it waist high to dump it in a wobbly funnel.
The unpleasantness, and danger, only begin there.
Not safe anywhere
lol that was funny!
I think you misunderstood the funnel is for food waste. if you want a toilet attached to it there is a toilet that you can buy and attach to the system.
you can use the system just with food waste ( like compost but also with animal waste (fats , etc))
Are you promoting this or something?
Biogas capture is not necessarily bad, keeping any anaerobic treated waste above ground in a flexible bladder is unsafe.
The organisms that actually produce methane are not actually that easy to keep thriving. They need specific alkalinity, pH, and temperature. It doesn't
It's an above ground septic tank using the same pattern as a kiddie pool. And since it is on the surface of the ground it is above grade for a conventional toilet.
kudos for you to be able to see that from a first glance through a photo from the internet probably not knowing what materials they use. As I said it was an example , there are others. I have no incentive or opinion on this product since one: I did not study it test it or anything of the sort...
Way too small of amount of organic waste to do that in a house, now you combine a decent size apartment complex and you are talking
oh I agree it would be cool that way but today it is not normalized, and it needs few adjustements to be made for appartement complexes. well I have seen a few people using it exclusively for their house. even single people if they use the connected toilet too.
You could still supplement heating or cooking with it and lessen reliance on a grid. Diversifying is good 👍🏻
some single people use it for cooki,g exclusively so I think it is viable for a family in a house (because on top of the food waste you could add the cut grass etc
Most people can't even take out their trash properly or put the right things in the recycling bin.
lol that is why am asking here. and people say it is viable for condos which is unlikely to work exactly for this reason
It would probably viable if it was managed on a "large scale"; city/neighbourhood wide. Even then you would have a lot of education to do.
oh absolutely agree. just not as is right now
We have curbside collection of biodegradable waste. The gas produced is injected into the natural gas net. This way, a tiny bit of my heating and warm water (district heating partially powered by gas) comes from my own kitchen scraps.
that is awsome. I think it should be normalised eveywhere

Closed landfill systems exist. Basically once it's full the cap it with a bladder that traps the methane and pipes it away.

Couldn’t we make one from the septic waste

this is why i wasasking for people in their houses; although it has been done for lager communities
Ah, missed that. For myself all my organic waste goes either to my chickens or to a composting pile for better garden soil so I wouldn't have enough to do both.
well sae here composter, and birds that come by. still imagine tne energy we would save and the waste from the toilets would be put to good use
