what is the feasibility of dung based power plant,?(Rs.200/per ton of dung).?

Question

other details:Regularly 10-15 tons cattle dung available,intersted in utilising it either for power or cooking production.Possibility and pre-feasibility basing on Govt.,UNDP,carbon trading,other international assistance for this renew able energy plant.

Answer 1

It does not sound feasible to me.

Answer 2

There are hundreds of biomass based power plants in the world. Cattle dung is less superior than cow dung.

There are many technologies that are available for converting cattle dung to power etc. But be careful, electricity laws for independant power producers in India is very complicated and often corrupted. You can get Carbon credits certainly, but time is tricking for you as 2008 is nearing, when the implementation period under Kyoto starts.

I suggest the following for you as an employee working in waste to energy and facility project management company:

a. Techno-commercial feasibility report to be prepared which should address the debt-equity ratio, agreement from lectricty board that they will buy power from you at a particular cost, transmission and power thefts, waste disposal and all environmental clearances
b. Once they the techno-comm report is availble, we can work into the formalities of carbon trading (mind you that the whole carbon trading process will take 1 year and it involves local environmental control boards - corruption etc).

May be you can look into integration of the cattle dung to power generation plant to agricultural industry, so that there can be better synergy. Isolating power plant may not be workable in India.

Answer 3

Hi,

Interesting question.

Can it be done - definitely
Is it feasible - might be

Dung (organic material) undergoes anaerobic digestion (fermentation) to produce biogas (which is a mixture of methane and carbon dioxide). The methane so produced can be burned to produce electricity, usually with a reciprocating engine or microturbine. The biogas can also be cleaned to produce a natural gas substitute.
So what you have suggested can definitely be done!

Now for feasibility. Rs 200/tonne is itself a big problem when looked at from a logistics/transportation point of view. Transporting something so cheap makes it difficult to make a large plant (which is what utilizes scale).

Now something that can be done is. A bunch of biogas plants (with co generation facilities nearby) or turning the biogas into natural gas used for LOCAL purposes. (Because getting enough dung to generate a large amount of power might be in feasible).

Combine the plants with a centralized administration (and such overheads), and a centralized method of packaging and selling the carbon credits which are so generated - then we might be talking of something worth pursuing.

Cheers!

And isnt this also supposed to be in business?

Answer 4

Make a big biogas plant and you can use the dung to make biogas as well as fertilizer and make lots of money out of it.

You can visit the link below these guys will help you build something.

Oh and just adding some figures , a 100 Kg Organic compost fertilizer sack sells for between 450-480 Rs. When sold loose it goes for about 6-8Rs /kg .

Cooking gas costs around 360 Rs for 14 Kg cylinder.

So you get the experts calculate the gas and fertilizer output ,input costs and do the math.

Answer 5

The new GREEN PEACE project in the Philippines will run electric jeepneys with battery charged from a methane gas fueled power plant . The waste from piggery is feed to biogas digester to produce gas fuel. This will reduce the cost of running the ejeepney from 1500 pesos of diesel to 150 pesos cost of electricity. Savings per unit is 1350 pesos. Previously the cost of a digester is 10000 pesos plus the cost of 75 kva genset is around 500000 pesos. So, what is the break even value? Dis regarding the cost of money say CAPEX of 1M. Only 20 units of ejeepney will break even the capital outlay to return in less than a year? Feasible? Isn't it medium technology?

Answer 6

In the Himalaya Mountains they use Yak dung to heat their tents. How about using it in your fireplace at home? The left over ash could be used for sweetening the acid smelling flower garden where everyone runs outside to heave their insides out from smelling the burning stuff. If you are serious about cooking with dung I refuse your invitation to dine with you. You are right about it being renewable.

Answer 7

That's the biggest load of crap I have heard in a long time. But seriously folks. Watch the episode of Dirty Jobs on the Discovery Channel where the guy makes the poo pots. He utilizes bovine excrement for all phases of his operation. It may be possible to do what you have proposed.

Answer 8

I don't see why it can't be done if it was designed well. Another venture is to add special compost worms and turn it into vermiculite fertilizer. Not only will it convert it into natural fertilizer but make plants grow better so we can have more oxygen in our already polluted environment.

Answer 9

Mouse droppings... they're sneaky little buggers that come out as quickly as we are snoozing and do their dastardly deeds fouling up my kitchen drawers and countertops... sheesh you will think of they might a minimum of sparkling up each and all the toaster crumbs... yet wait perchance they did.... there they're in a neat pile over there interior the corner...

Answer 10

Cattle power, you could say, has been in power for years now, the use of methane has been used for many years. Some farmers use it to power their furnaces, they even bottle it for their tractors like propane.

Answer 11

Ofcourse it is feasable . Gobar gas plants can be installet at low capital costs .Entire village can club their resources and benefit.
Govet can provide subsidy and technology support.
