Bio-Gas Production FAQs
Q&A on biogas systems
- POST a QUESTION or COMMENT about biogas production and use systems as an energy source
Biogas & bio fuel productions systems:
This biogas article discusses designs, methods, and projects for biogas production to obtain useful renewable-energy methane gas for use as a fuel.
Our page top photo of the KIST biogas project in Rwanda, described by the Ashden Awards for sustainable energy program is from the Ashden awards program.
Watch out: Because sewer gas contains methane gas (CH4) there is a risk of an explosion hazard or even fatal asphyxiation. and the chance that there are possible health hazards from sewer gas exposure, such as a bacterial infection we include here some safety warnings for people undertaking amateur biogas production projects.

In addition to the equipment producers listed above the research experts above could perhaps provide design specifics that are suitable for your project;
Also take a look at the bottom section at the end of this page titled
Technical Reviewers & References
where the Kigali Institute of Science may be able to offer you detailed help.
I have researched and have added here other sources of additional designs for biogas production that I can find, though I suspect that ANY cookbook or off-the-shelf biogas reactor design is going to need to be adapted to build 5000 low-cost systems - I trust that you want to avoid high-tech or expensive and perhaps unreliable controls and components.
Some of the biogas design articles you will now find on this page in free down-load PDF file format are quite modest in concept and materials and might be suited for some of your users.
You may need to wait a few hours or to clear your browser cache in order to see the page above as I have just updated it.
Thank you for asking me about this - don't hesitate to correspond further.

The article above lists several biogas equipment producers as well as research experts. With respect, am asking for a detailed steps/design specification for building and operating a biogas system for 5000 villages here in Nigeria.please help me out in this project

Arvind,
The article above lists several biogas equipment producers as well as research experts. I would contact them directly. With respect, asking for a detailed design specification for building and operating a biogas system for 5000 villages handling human and dairy cow waste as an off-the-cuff reply at any website, including this encyclopedia-one is not feasible.

I Want to use bio gas plant for the new generation fuel ,I want to know how we can produce bio gas at larger scale and this will very help full I app 5000 villages in which app. 30 dairy cows then total app. 150000 cows which can yield about 1500000 excreata in one day
which can produce about 1 million bio gas in one day that's why tell me how i will implant it

Indeed we've spent time with an environmental engineer in Mexico whose hog slaughtering facility makes good use of biogas - it's a model installation in Penjamo.

Oh also electricity. Plus I wanted to make the comment that my dad with a friend installed a small goober gas system in northern India. The run off from 20-25 dairy cows provided enough gas for 30 households for cooking.
I visited that orphanage in 2007 and that same system was still running the place bar a few small repairs
. In 2010 they replaced the cement tank and dome that regulated the pressure. What an amazing idea and use of dairy cow byproducts! Wish the US would take this on in regulars to the hog confinements and cattle barns!
Just doing some research in to this wonderful idea. My husband and I live in Iowa where temperatures can drop above ground to the -20's at its worst.
I am guessing during winter times fermentation and creation of biogas from a septic and manure collection system would almost completely stop. Is my assumption correct?
Also is there research out there in regard to how many cows, pigs, humans it would take to provide enough waste to produce fuel for heating and cooking for an average American household?
Especially one living in regions that are cold for almost 1/2 of the year?

It will produce gas

Hi, I am looking for some guidance. I have a septic tank suction pump truck in Vava'u , Tonga.
I am considering purchasing a bio gas system to process the waste from the septic tanks I pump out. My questions is....
The waste I collect from septic tanks is already broken down. Weill it produce bio gas or has the gas already been released and is no longer available to me. Please respond here and also to my email ianjones@hotmail.com Thanks Ian

i have been running a generator that is fuled stright off my septic tank for years all rural houses used to do the same in 25 years i have had no problems
sounds like you just wany to sell some new fangled stuff to me.running stright off septic is fine.

Roy for space and to allow citations I repeat your question and provide a detailed answer at the bottom of the article above.
I'm researching further regarding small home biogas system controls. Let me know what questions remain or use our page bottom CONTACT link to find email to send me photos of your system.

I am referring to a home made bio gas tank. Kindly let me know whether if there is any danger to use a simple bio gas system at home with out installing a non return valve on the gas outlet pipe to prevent the system from any back pressure. Thanks.
Question:
(May 30, 2011) Technology Help! said:
In cities there are sewer lines, sewer treatments plants, water treatment plants, in rural areas many homes have septic and/or cesspools that produce methane type gases.
Where there are connections to every home...couldn't there be a "buyback" from the towns to utilize the waste that the citizens produce that could be turned into energy for the towns and cities?
Landfills sometimes have (North Attleboro MA) pipes that hit the methane pockets and are a constant torch at the landfill.
Rural homes have cesspool/septic tanks in every yard. Isn't there a product that could be installed that could detect the carcinogens and filter them out leaving clean fuel to be used for the homeowner?
There are outdoor woodburning furnaces that can be connected to the home, but the fuel burnt is still exposing the atmosphere. Isn't there something that can be utilized like the outdoor (Janco) woodburning furnace that could utilize the methane being produced while filtering out the bacterial components and carcinogens before they reach the air?

i would like to know where to purchace this small scale domestic bio gas component where u connected to your existing sepict tank

Reply:
Munyaradzi,
A review of the sources and suppliers of biogas digesters described above shows that principally the systems focus on vegetable and kitchen waste for small home systems or on manure for some larger commercial systems.
We have added biogas kit and component and design information sources to the article above.
Thanks for asking.

The Ashden Awards for Sustainable Energy Allington House, 150 Victoria Street, London, SW1E 5AE, Tel. +44 (0)20 7410 0330 - http://www.ashdenawards.org

The Kigali Institute of Science, Technology and Management (KIST), has developed and installed large-scale biogas plants in prisons in Rwanda to treat toilet wastes and generate biogas for cooking. After the treatment, the bio-effluent is used as fertiliser for production of crops and fuelwood.
Large prisons, each housing typically 5,000 prisoners, are a legacy of the troubled past of Rwanda. Sewage disposal from such concentrated groups of people is a major health hazard for both the prison and the surrounding area. The prisons also use fuelwood for cooking, putting great pressure on local wood supplies.
Using biogas digesters to manage animal or human sewage is not a new idea, but in Rwanda has been applied on an enormous scale, and with great success. Each prison is supplied with a linked system of underground digesters, so the sight and smell of the sewage are removed. KIST staff manage the construction of the system, and provide on-the-job training to both civilian technicians and prisoners. The biogas is piped to the prison kitchens, and halves the use of fuelwood. The fertiliser benefits both crop production and fuelwood plantations.
The first prison biogas plant started operation in 2001, and has run with no problems since then. Biogas plants are now running in six prisons with a total population of 30,000 people, and KIST is expecting to install three more each year.
The Ashden judges were highly impressed with the scale of these biogas plants, and the benefits which they provide in a difficult environment - sanitation, fuel and new skills for prisoners. They also recognised the significant potential for using such systems in other institutions like schools, hospitals, and on dairy farms - work which KIST has started to undertake.
