Cost of family size biogas plants

[Manoj Kumar.M]

Dear All,

 

My query is what would be the installation and annual O&M costs for family size biogas plants. If that is too general, any capacity oriented answers would be of much use. Thanks in Advance.

 

With regards,

Manoj Kumar

Biotech, in Kerela, is an NGO that specialises in pre-fabricated residential biogas digesters of 1 cu.m capacity. They cost around 10,000 each (2007 figure - without subsidy). With about 3-5kg of daily kitchen waste, it can provide cooking gas for upto 1hr.

[Ajay Chandak]

We have a design that can be constructed and installed in Rs. 15000/-. This is 4 CUM capacity plant and takes care of 100% of your domestic needs if feed material is available. We have opted for higher capacity of 4 CUM (Gas holder of 2 CUM) as we understand that daily monitoring and feeding digesters is not practicable and we need some extra storage if we plan to give up fossil fuels. This technology will also be demonstrated during the workshop we are conducting from 1st to 3rd March 09. I have already posted details of the workshop on Green-India, same are available at http://www.princeindia.org/Announcement%2018%20Jan%2009.pdf

Hi Manoj

Sintex industries has a biogas plant which cost around 15000 Rs. check
the site
http://www.sintex-plastics.com/deenabandu.htm

If you are do it yourself kind of guy you can build one easily for
less than 5000 Rs.
Check this site.... they also sell ready made one.

Is this not a lot of wste required...........Kitchen waste so to say.Honestly so much food should never be wasted.

..........A family of four in our house consumes say 1 kg of vegetables and maybe another kg of fruits and they are not wasted. If we map our wastage which would mostly be peels it is not more than 300gms maximum. 

How does one generate so much waste? Is there no other way of cooking?In almost all parts of India we can use solar cookers for basic cooking that is for veggies, dals and boiling meat,except of course for chapatis and frying. How much gas is required for Chapatis ?...........say making of chapatis for twenty minutes a day......may be then we can store enough waste and use it for biogas.

Energy needs cannot be met by one solutions and it would make a lot of sense to marry different possibilities and I would like to combine solar, biogas with small biomass cookers like Mitra cooker to be looked into for domestic needs.

One of my postings on this thread has missed the attention. We have developed a different design of gas holder, that combines advantages of steel and plastic drums. This is 4 CUM plant with cost of Rs. 15000/- and requires 7 feet dia. space.

We are using biogas based on food waste and solar parabolic cookers. We have given up LPG since last three years. Visitors are welcome. Technology promoters are more welcome.

if you have not sufficient food waste you can mix used flowers ,grass cliping,or you can purchase 'CHOKAR' from flour-mill or market it will cost you approx.Rs.5/ per kg., this will work.

[Biome]

OK that is a suggestion.................so will have to buy minimum two kgs of Chokar for everyday use........and how was this Chokar being disposed off till now? Considering in India nothing really goes waste traditionally!

The overall intention of this debate should be how should we look at our energy needs and how best can we use what we get almost free.

Dr.Chandok do let us know how much does the parabolic cooker cost? We have seen in China these made with small pices of mirror on a ferrocement surface and their cost was merely 100 Yuan close to RS 600. These were made in every village and women made them easily.

Hi

This is no debate the poor guy asked a simple question....what would be the installation and annual O&M costs for family size biogas plants.

Anyways I agree solar cookers are good option and the best if you are willing to do it but frankly its more of a lifestyle/cooking style change. Biogas is similar to LPG which most people are accustomed to using.

You can also ask you Sabziwala to give you rotten vegetables which you can use in ARTI type biogas plant.

[Ajay Chandak]

Our experience is that food waste (suitable for biogas) generated inhouse in Indian families is neglegible. We Indians do not waste any food. Vegetables cuttings are no good stuff for biogas plant. But our hotels have lot of food waste. Different materials those are suitable for biogas plant are fruit wastes (From market), flour waste (from flour mills), non edible fruits, all variety of non edible oil cakes (edible oil cakes fetch good price as cattle feed), all kind of seeds etc. Since last three years I am using hotel waste from a hotel adjoining my house. This is a small hotel, but still generates waste that can feed eight families comfortably. He does not have space to build his own plant. Quality of gas with food waste is excellent. It burns with great blue flame, sometimes better than LPG. One of the biggest advantage people forget, this gas is extremely safe and no chance of having any sort of blast.

We recently proposed to the corporation and got a project approved. Proposed project has an idea that waste from hotels is to be collected in a separate vehicle and to be shifted to biogas plant in central Jail. The biogas will be utilised by Jail authorities and waste will be converted to earthworm compost. The project is accepted by the corporation, Jail authorities have given the clearance and have shown willingness to offer space. The issue has stuck up, who should finance the project, corporation or Jail authorities? we are trying to solve the deadlock. Corporation has many advantages as their trip distance (to the dumping yard) is cut down by 75%. Less waste reaches dumping yard and the site life is enhanced. Jail people get gas for free and can make some money from wormicompost project. Let us see how the things develop.

Dear All,

Maybe a wrong word used.debate.....is dialogue better?

I think it is good to discuss more than just a question asked since we get more elaborate answers and if the person who posted it is still keeping to the thread he/she will get better answers than ones replied to directly to the question.

Now, from the posts we have a good idea of sources for the waste, and also some other possibilities besides bio gas.

Prof. Chandok it would be nice if you could elaborate a little more on the parabolic cookers and their costs.

Regards.

Parabolic cookers are great devices to cook food fast, in reasonable time. There are many gadgets available in the market. Popular ones are SK-14 (1.4 m dia. cooker) domestic cooker and a new design in square shape we have introducted some 8 months back. Both these cookers require around 6 feet dia. space. They take around 50% more time as compared to cooking gas and in summers sometime these gadgets compete with cooking gas. Taste is great. You may see videos on following links for setting and with pressure cooker in action.

 

http://in.youtube.com/watch?v=QBI4I6b1ovQ

 

http://in.youtube.com/watch?v=KmkkFPFGAeI

 

 

Community parabolic solar cookers are 2.3 m dia. dish cookers. We had more than 400 installations of these cookers catering to 20000 people. Major installations of 360 such cookers were done for tribal ministry in Maharashtra for their residential schools, incidently this was world's biggest solar cooking project using concentrating dish cookers.

 

Other options people might be aware of, is Scheffler concentrators, which facilitates indoor cooking as well.

 

Approx. cost of these units, Domestic parabolic solar cookers around Rs. 5000, Community 2.3 m dia. around Rs. 25000 and Scheffler concentrators start at Rs. 75000 and depending on applications can be multiplied to any scale. We are organising training workshop from 1st to 3rd March, for developing manufacturers for these solar cookers all over India and I had posted the announcement on this group some time back. The response is very encouraging. We have received more than thirty applications from nine states and fifteen cities. Details are available at http://www.princeindia.org/Announcement%20update%2029-1-09.pdf

madam Malati,

you can get an appropriate plant alongwith effluent disposal , 

kindly tell us, quantity of waste genrated their. 

[Ajay Chandak]

Different options are,

 

In solar energy option, I will recommend a direct cooking system, Scheffler concentrator of 16 sqm size. This is capable of cooking up to 100 people easily. This is a bit expensive cooker, costs around Rs. 1.6 lakhs, but this is autotracking and can work throughout the day. This cooker also has a facility to cook indoores. Concentrator is outdoors while the focus is indoors.

 

If the budget does not permit this, then one can go for 2.3 m dia. dish community solar cooker. This cooker is capable of only boiling applications and can cook for 40 people and costs around Rs. 25000/-. This is manually tracked and outdoor application.

 

Biogas plants: Canteen/hotel waste biogas plant can be constructed for any capacity. Depending on quantity of waste one can decide the biogas plant. As a thumb rule 10 kg of waste per day produces around 1 CUM of biogas which is equivalent to 400 gms of LPG.  Cost of the system is around Rs. 15000/- per CUM of plant. We have executed one biogas plant for Hotel Ganapati Palace in the city of 15 CUM capacity, working great from last two years.

Ajay Chandak.

We need to have some sustainable supply of feed material for the biogas.  This could be hotel waste, flour waste, all types of fruit wastes, all types of seeds (mango, tamarind and similar), all types of non edible oil cakes etc. I feel that if you are amongst first few who constructed biogas plants then you can sustainable feed supply by purchasing flour waste from the flour mills. If the biogas plant number increases then we can develop some vendor who can purchase oil cakes and distribute the same to the people on weekly basis.

 

I started purchasing flour waste and use the same in my biogas plant for almost one year. Then we shifted to hotel waste. There is an adjoining hotel, and the people are more than happy to dump the waste in this biogas plant. Our watchman helps them. That is how the plant is running now. I feel managing plant on flour waste is practicable to many people.  Now we have surplus biogas, much more than we can consume, still we use parabolic solar cookers for rice and pulses as we are used to the great taste of solar food.

sir,

Actually we have developed a plant which is costing much less per cu.mt./gas, for family of five we need approx. 1/2 kg. gas per day awhich could be easily produce by the plant.we used recycled drum for this and results are good, costing just Rs.4500/- approx cost vary as recycled  materieal never has a fix price.in every market.

we are using a mix of kitchen waste excluding onion/garlic contents in a

ratio of pre decomposed kitchen waste1(one) part +2 time water mix it as slurry pour it in fermentor add 2 time more water . it's a unique only approx 18 lit feed stock.

working nice.

[Ajay Chandak]

Dear Ms Sunita,

Nice to know about your plant made out of drums. I only have doubts about the capacities. Half kg LPG gas per day converts to 1.25 CUM of biogas per day, i.e. 1250 liters. How you managed this quantity by using drums etc. I will like to know the sizes of the drums and may be few pictures. What I have seen in the market are all below 250 liters capacity. If you can manufacture something less than Rs. 5000 worth promoting on large scale.

Regards,

 

Prof. Ajay Chandak.

Hi Anuradha,

I would recommend household biogas digester only if there's an additional source of organic waste than kitchen waste. If you have a restaurant nearby and can get them to give their waste to you, you can go for it. 

A typical 4 person household generates only about 0.5 Kg kitchen waste per day on average which is not sufficient to generate any significant amount of gas and therefore wouldn't pay back the amount you spend on the digester even if you make it yourself and thereby save on the ridiculously priced home digester by the likes of biotech. 

A better alternative to save cooking fuel expense and carbon footprint is to pursue energy conservation and energy efficiency in the kitchen. I'll be happy to elaborate on this if needed. 

Thanks,

Manu

Anything smaller than 1CUM will not generate enough gas. 

That's not correct. You could build a mini digester of one fifth the size (200 litre) with a separate gas holder made of polythene sheet and generate enough gas for a household of four. Since kitchen waste has small retention time (it digests quite fast compared to cattle dung), there's really no need to go for size as large as 1000 litre for a household. 

The 1 cubic meter household biogas digester design typically made of two water tanks has been pioneered by ARTI and popularised by biotech and others in India. But if you separate gas holder from the digester and go with a plastic bag gas holder, you could easily reduce costs by half. The design I'm talking about is popular in China and several South American countries with hundreds and possibly thousands of installations. 

The key problem of ensuring feed stock supply on a regular basis however remains and unless you can provide the supply, it's not recommended for a small household.

Hello Manu,

Can we add garden leaves/waste along with kitchen waste to make up to two kg?

In any event you should share energy conservation in kitchens

Hi Ritu,

You will need to have a large garden to get 1.5 kg of green organic matter per day (dry leaves won't generate methane). Most urban homes do not have such gardens. In any case, methane generation capacity of green leaves doesn't compare with kitchen waste.

Will make a new post on energy conservation in kitchen.

Dear All

 

There is lot of activity in developing a domestic LPG grade  biogas plant with a patented built-in  gas cleaning system so that it can work on the existing LPG stove.

This was demonstrated in Rashtra Pati Bhavan new Delhi few months back and kept it in MNRE Delhi as a demo plant.

As usual in Govt it is nobody’ baby. It is idling now not in use.

The developer Scalene green energy is further modifying it to increase the efficiency to suit individual house needs.

They claim with kitchen and food waste of each house it can produce sufficient gas required for the individual house need.

As per the developer in 6 months they will commercialize it.

On successful commissioning of this system it can reduce LPG import substantially

Please wait have little patience things are going to happen

Scalene is a leading player in Inida in high-end biogas technologies (or what they call 'serigas') but if they've claimed that household kitchen waste can meet all the cooking fuel needs of the house, they are misleading people. Also, because of the high technology involved their solution is likely to be expensive.

Hello,

I have a simple query: Would it not be possible for us from this group to deliver a concrete energy solution altogether? after all there are many qualified professionals here and moreover there are enthusiastic people on a single forum. 

But for a solution, we need a problem and here it is: There is a village named Dhamna in Maharashtra with 20 homes and electricity is available for 4 hours maximum, gas cylinders are available 25 km away, water is salty which has affected the crops on a large scale. They have a small dam being constructed nearby but again the water quality is not acceptable at all.

So let me know in case your expertise can be used to deliver a complete solution for this village. 

I am already working on electrification with solar PVs here and I reckon a 2kW system (costs around Rs. 3 lakh) can suffice their electrical requirement. 

Regards,

I have the same opinion as Manu. We can't generate sufficient methane (gas) from the kitchen waste (alone) of a small family of 4.

I have a bio-gas plant in my house and is using it for about 2 years. Now-a-days we are getting only 15-30 minutes of gas (uses a single burner stove) daily. We are using only our kitchen waste for that. 

I know another family who are using their toilet waste and kitchen waste together for bio-gas. They are getting more gas (I think, for more than 1 hour).

FYI: The main tank of my bio-gas plant is under one of our bed room. It has been constructed using bricks, cement (mortar), iron rods etc.; not the fiber one by the companies like biotech. I got Rs.8000 as Govt. subsidy. The total construction cost (including labour) was between Rs.20,000 and Rs.25,000.

Dear Manu,

 

I wanted to install the biogas plant for my place. We are 8-10 people. Recently, i made my survey on small biogas and still not installed the unit.

I have already tie up with near by catering for vegetable waste to feed my small bio-gas plant.

 

a. Visited scalene, The plant they have is bigger one 1000 ltr capacity in their factory it is good. Very impressive. They have 2 Gen sets it is generating the power for their factory. They are using the gas for the kitchen.

 

Their Small capacity for 6-10 people house hold biogas plant is still under commercialization. It is a product.  I do not think it is a big technology. But cute compact, neatly packed product idle for house hold. No smell, STILL DO NOT KNOW WHETHER HOW MUCH GAS IT CAN GIVE ME.  Their product cost Rs.60000/- Today's gas price and 6 cylinder proposal. It is a good bet.  The space required is 6x4 feet. max

 

b. Visited other plant in mysore in a research colleage. Their 500 ltr capacity plant. These system use cow dung also. But gas output is not great. their technology is not suitable for small household. The space required is 10x10 feet.

 

c. Some time back, I saw Coimbator based company small capacity plant. It was costing Rs.25000/- for 4-6 people. But their product is based on Mild steel sheet tank. I felt the price is ok for the design. But not able to understand the GAS Output. The space required is 6 x 4 feet max

 

I am also still not understand, which bio-gas plant is best suitable for my place.

Thanks Rajesh for clarifying this and again for sharing your experience. First hand information on actual experience is invaluable. 

So if a 6-7 person household with two kitchens generates biogas for around 20 minutes on average per day, a 4-person house with a single kitchen would generate enough gas to run the stove for approximately 10-12 minutes each day. Enough to make a few cups of tea. Certainly won't get your money back. 

Prof Ajay Chandak who is a long time developer of biogas digester designs, writing previously in this thread, has also emphasised the need of tie-ups for feed stock supply when going for a household biogas digester. 

Thanks,

Manu

[Manu Sharma]

Nagraj, If you have assured feed stock supply, you can make your own digester with ARTI (Pune) design. They sell a CD with video instructions. All components are easily available. You can make it yourself or get it made with the help of a plumber.

[Rajesh GS]

Hi Manu,

It's true that for efficient utilization, we need to tie-up with some vegetable shop or butcher shop. But care should be taken that the waste won't contain plastic, egg shell or acidic waste like large number of tomatoes, oranges etc. (as warned by the bio-gas plant builder).

We need to try bio-mass rice cookers ( http://www.island.lk/2009/03/21/satmag6.html ) and bio-mass pellet stoves ( http://www.firstenergy.in/?page_id=177 ) also.

Thanks,

A cheaper alternative to this is Sarai cooker developed by ARTI which works on the same principle, has multiple compartments, and runs on charcoal. Then there are a large variety of efficient wood burning cook stoves. Envirofit's products have been popular in some parts. 

For commercial applications, an organisation in US called Aprovecho Research Center has developed what could be the world's most efficient wood burning stoves of large capacities. They have around 40 years' experience in developing efficient cookstoves and they make 60 Litre and now even 100 Litre cookware capacity stoves that burn "almost as clean as methane". 

 

and bio-mass pellet stoves ( http://www.firstenergy.in/?page_id=177 ) also.

Although this appears to be efficient and clean burning, I won't recommend pellet-based stoves as then you are dependent upon the pellet supply chain. Wood and charcoal are much more easily available fuels.

      Dear Mr Mandar,

  I appreciate your initiation for installation of 2 KW SPV Power plant for meeting the minimum needs of electrical power. 

  I suggest the following solutions for meeting their cooking energy needs

       Construction of 1 or 2 Cu.M capacity B G Plants fro individual families having 3 to 4 cattle.

      Supply of Solar cookers either box type or Parabolic dish type to suit their cooking process

       Raising energy plantation in Village panchayat  waste land, to operate BM gassifier for power generation as substitute 

       LED lighting for minimizing the lighting load

       We may increase the capacity of SPV Power plant to operate pump for lifting water from available source and also operate small electrical gadgets for community purpose.

 

      Regards

Hi Mandar,

I support all suggestions made by Sri Rama Raju. For agriculture, I'd suggest using pitcher irrigation to fight salinity in water. According to  Central Soil Salinity Research Institute (CSSRI), karnal, pitcher irrigation can work with saline water to some extent for vegetable crops. This will also reduce water consumption and energy needs by 90% and has the potential to increase crop yield drastically due to its auto-regulative capacity. 

Here are some studies that provide more info. 

Pitcher irrigation: a water saving technique

This page provides a basic overview of the technique and lays out its various advantages.

Performance of Pitcher Irrigation System [PDF]

This paper looks at determining the optimum pitcher size and argues that use of small sized (cheaper) pitchers with high hydraulic conductivity is comparable with using large sized (more expensive) pitchers although such the former would need to be refilled more frequently.

Development and Revision of Design Criteria for Pitcher Irrigation Systems [PDF]

This is a summary of a longer paper that determined that there are three important design factors that influence movement of water from the pitcher. These are a)  hydraulic conductivity of the pitcher (most important), b) surface area of the pitcher and c) wall thickness of pitcher.

The auto-regulative capability of pitcher irrigation system [PDF]

This paper discusses the strong auto-regulative capacity of pitcher irrigation system looking at how evaporation influences movement of water from the pitcher.

Water Use Efficiency And Saving Through Pitcher And Polyethylene Bag Irrigation [PDF]

This is an abstract of a paper that indicates 90% higher yields in pitcher irrigation system compared to polyehtene bag irrigation.

We have designed  a co operative biogas system for a few villages  in Gujrat. The system is very simple. There are 2 nos  85 cum/day  plants  which are based on KVIC design  approved for the government subsidy.  We have added little bit of automation in mixing and feeding the  gobar slurry.  The gas is passed throgh what is called  as pressure regulating device. The device regulates the pressure of the outgoing gas to about 600 mm WG pressure. The gas is distributed through pipeline to all  houses in the village (about 150) . The biogas is burned in regualr LPG burners. 

The gas is  supplied for 4 hours . 2 hours in morning and 2 hours in the evening.  The villagers are expected to pay about Rs 150 to the society every month.  The households which contribute  gobar  are given a set off  based on  weighed gobar from the monthly bill. Some villager actually earn out of this dependng on gobar supply. The milk from this village is collected by SUMUL  dairy and are paid for the milk contributed.  The slurry is converted into vermi compost. The SUMUL dairy has a buyback arrangement for the vermi compost also.. 

The entire project cost about 25 lacs. 90 % subsidy was given by Gujrat governement.   

There are more projects like this proposed by Gujrat governemnt.  But may be of double capacity.

The village is is self sufficient is cooking gas.

Very good info, thanks to all & Mr Manu.
We are planning to provide organic waste converter for apartment complex of 384 flats. Can some one pl suggest BG plant for this complex ? Can we produce electricity using this gas,that can be used for common areas ? Can we synchronize the gas produced to our reticulated gas supply ?

Dear Mandar,

I should add to Vishwas Gokhale's post below that the model he mentioned has been not just socially rewarding but has also been a financial success. This was discussed in an earlier discussion two years ago archived here:  Highly successful biogas business model. 

Thanks,

Manu

To the last question - yes, absolutely. After purification biogas is indistinguishable from piped natural gas. If you have piped natural gas infrastructure already in place in the apartment complex, do not use it for electrification. Use it to supply to PNG system. 

With electricity generation, 2/3rd of the gas in lost in conversion so the first preference should be to use biogas for cooking. Since you already have PNG infrastructure, such a system will have quick payback.

Hello Vishal,

Where do i get details for this plant? Does all state Government provide same subsidy? I am looking for something to start in Maharashtra...

Thank you Manu and everyone of you,

 

I have been speaking with the investors from my own company for the rural electrification as a 1^st step towards delivering a complete solution for a village. I am also speaking with Greenpeace to cater the same solution. I will keep on updating you over the details and/or the milestones I come across.

 

Initially, I am planning this step of delivering electrification with solar photovoltaic systems as it is easier for me to convince the financers and then I will be moving on to other sustainable solution.

Dear MANOJ,

A family having 4- 5 Members generate a kitchen waste including the raw /cooked food that is just sufficient need for 0.5 M3 plant with digester capacity 500lts and 300 lts

gas Holder . This will support you 45 Min Morning 45 Min evening time gas for a single burner stove . IT all depends the nature and mix of food you feed.

There are  a few other parameters affecting gas production .

FRP Moulded or Roto Moulded ( Sintex Type) HDPE / LLDPE moulded ready to install plants are available in Market ,

FRP Moulded plant with water Jacket having 500 lts digester + 300 Lts Gas holder will cost you about  Rs 8500- 10000 and sintex will be around Rs 11000/-

[Ranjay Singh]

Hi All , I am not sure where my comment will appear but am delighted to go through these fruitful conversation as am new to it. I would surely wish to explore the cheapest way to make domestic biogas as it's not only about subtracting LPG from it but also would help to keep society cleaner. Also would love to explore home made solar pressure cooker as Chitra has explained referring China.

Warm Regards,

Ranjay Singh
