gud day sa lahat,,,ask lang kung safety ba ang biogas kung may leak? gaya ng mga LPG pag may leak dilikado…..thankz

@david, pwede. in-fact ang maynilad at manila waterworks ginagawa na yan. kasi once in a while, kinukuha nila ng libre yung laman ng poso-negro sa mga bahay.

Sir, how about human waste. Pwede bang i convert ito into bio gas?

kuya, gradutaing student po ako under architecture.. meron po akong thesis proposal pra sa comletion ng requirements pra maggraduate.. residential unit po xa na gumgamit ng biogass sna at mga solar panels tska wind turbines.. maari po bng pahingi ng profile kung human waste at kitchen garbage lng gagamiitin pra magproduce ng methane gas at kung gano krmi ung volume at kung ilang days or weeks bgo makapagproduce ng sapat na bio gas.. at kung gano karami ung volume ng bio gas.. at kung magkano estimated cost nung construction.. maraming salamat po… God blesssssssss………..

I am basically a newcomer in contract growing industry. Our farm is located in Pili, Camarines Sur, it’s a climate control system or also known as a tunnel vent system. It houses 26k birds and we use plastic slots instead if ipa or rice husks. Thus the manure goes thru the holes of the plastic slots into the flooring of the house or building. Now, here’s the problem, when the manure accumulated is about 5 inches thick ammonia starts to build up and sometimes some chicken dies. Also, when we start collecting the chicken manure at harvest time it emits foul odor specially when they’re placed in the plastic sacks. My question is this, how could I convert the manure into biogas, so instead of dumping them some place we might as well use them for brooding. we actually use or consume 15 cyl of 50kg of lpg per cycle.. Can u help me put up biogas system in my poultry? We will appreciate any information or help you can extend to us…

Thanks a lot and our best regards!

Many believe that with a biogas digester — facilities like poultry dressing plants, slaugther houses & abattoirs do not need Waste Water Treatment (WWT) systems as digesters replace WWTs. They are wrong but not completely wrong.

Simple lagoons used as WWTs produce biogas that escape into the atmosphere. As biogas is a potent greenhouse gas (GHG) that contribute to the worsening Climate Change & Global Warming problem, that is like releasing poison into the air.

Complex & compact WWTs produce less biogas because they are aerated. Biogas production needs an anaerobic or “no-air” environment.

In the past, installing a biogas digester was done to collect biogas for use as fuel. That has changed.

Now biogas digesters are used to capture biogas & keep it from escaping into the atmosphere. Doing so still provides a fuel that can replace expensive petroleum fuels. But even if the biogas is just “flared”, the project qualifies as a Clean Development Mechanism (CDM) of the United Nations Framework Convention on Climate Change (UNFCCC) & can receive substantial carbon credits (in monetary form as an incentive, subsidy or reward) — for doing something good for the world.

I apologize for the long reply. You have a good question & it deserved a good answer. Finally, I suggest you ADD a biogas digester to your WWT. Your WWT will operate more efficiently as it will have less work to do, you will get biogas for use as a fuel & you could be “rewarded handsomely for doing something good.”

Simple biogas digesters are best fed with plant (high carbohydrate & starchy) wastes or by-products like vegetable scraps, grass cuttings & leaves; food wastes like rice & bread; and, manures from animals fed with grass & grains.

We recommend pig, carabao, cow & poultry manure as they are abundant & do not need to be chopped or shredded like plant & food wastes.

Digesters fed with high protein stuff as what you have (20-25% cp) reportedly produce more biogas but they require more complex digesters as pH is usually high & fluctuating that it has to be monitored & managed.

All digesters work best at neutral or pH=7 & ambient temperatures as they are in the Philippines. In temperate countries digesters have to be warmed when it is cold.

I hope this information helps. Please also check our website that has been the source of the information described above.

we are consultants for poultry dressing plants. feathers, mixed with manure and some innards are wastes we generate. we plan to dissolve it into a slurry using some enzymes. resulting product is more or less 20-25% cp with ph 10+/-. can we feed it to the digester to get biogas? pls send reply to my email address: dexter_olito@yahoo.com. thanks

I am just wondering how much chicken dung is needed to produce bio-gas. I am working in a poultry dressing plant as its plant manager, although we do have quite a sizable quantity of chicken dung aside from other organic waste, e.g. feathers, blood and innards. We either truck it to near by rendering plant for rendering processes and for them to dispose what they can not render.
Given, that we are using diesel fired boiler to produce hot water from steam for scalding, we are faced with the stiff cost considering the high cost of diesel fuel, while we manage to convert to firewood/coconut shell fed boiler, we still look at the possibility of producing bio-gas from chicken dung and other wastes that we have. Our neighboring dressing plant manage to operate a bio-generator however,they have to truck in additional animal waste to produce these bio-gas adding to the increasing BOD and very poor quality of their waste water?
I would like to know your opinion on this?
Thank you and there be more Pinoy Inventors herein!
Mabuhay!

Your write up was very informative but will want to know if there is a means of extracting liquid Ammonia from poultry litters.

sir, what are some modification to make the plastic drums as a digester? is the rice straw is as effective as the manure?

more power,

I have an existing piggery and I would like to know the complete details on how to construct from digester to methane storage container. Maybe complete drawings and materials details to make me build it safe and effective way. Since I’m still working overseas and I need it during my vacation time before this year ends.

Thanks a lot
