Indian Biogas Association

The association was founded in 2011 and isnow mushrooming. The sole motto of the

i ti i “ ti Bi iassociation is “propagating Biogas in asustainable way”.

Biogas Plant – An Understanding

M M M

Three important rules for Biogas production: Mix well, Pump/feed well, and Heat well!

Substrate from Agricultural, Urban and Industrial origin

Cow Dung poultry litterCow Dung, poultry litter

Agricultural residues as rice straw, banana stem, maize , ,stalks

Sugar mill press mud, Distilleries spent wash, Sago plant effluent

Municipal Solid Waste, slaughter house waste, vegetable market waste,vegetable market waste, kitchen waste

Silage from agricultural crops g g pas Napier grass, Sugar beet, Sugar cane, Maize

Modularisation

Ca 45 000 m3 biogas/dayCa. 45,000 m3 biogas/day, Liquid fertilizer storage capacity ca. 48,000 m3

Organic fertilizer

Weighted average arable land of world:Weighted average arable land of world:

~40% of land area, whereas India has

~61% of land area as arable land i.e.

1,697,000 square kilometers

Weighted average organic farming in

world: 242,708 hectares (Total =

21,358,307 hectares), whereas organic

farming in India is just 41,000 hectaresg j ,

Chemical fertilizer consumption in India:

16,122,580 metric tons, which could be

reduced by the use of organic fertlizer

Rates for organic fertilizer can be veryfiedIf you think organic food is expensive, have you priced cancer lately?

Not to forget – Biofertilizer is an intrinsic part of revenue

Scenario

Scattered marketScattered market

No established player at national level

Market needs someone offering end to end solution

Experienced and skilled workforce is lacking

Government active intervention is needed

Promotion of organic crops is lacking

Different approach is needed for small, medium and large scale biogas plant promotion

Supply chain management is to be streamlined

Socio‐economic model of Biogas: An example

Gobar Bank Concept

• Bhitbhudrak model showed the importance of social

Project Uniqueness

• Bhitbhudrak model showed the importance of social engineering along with technology to make biogas a success

• The design was kept very simple and yet robust• The length of pipeline in the village is 2500 meters• The villagers are facilitated with cleaner and consistent source

of energy for cookingof energy for cooking• Improved economics of village:

‐ By way of providing more earnings from dung

‐ By way of improved crop production because of use of organic fertilizer• Improved health and hygienep yg• Providing smoke free atmosphere into kitchen• Providing cleaner environment in to village • Women empowermentWomen empowerment

Muni Seva Ashram: A Case Study

Geographical location MSA

• Near Vadodara close to the district border to Panch Kola and• Near Vadodara, close to the district border to Panch Kola and not far away from border to Madhya Pradesh.

• Road and grid access are quite good.Road and grid access are quite good.

• Distance to industrial sites (Apollo tires, Suzlon, etc. are quite near, so there is a good chance for third party buyers for power.

MSA Mission

"To serve the deficient and needy sections of the societyTo serve the deficient and needy sections of the society,without regards to cast, creed, religion or financial status of therecipient, employing the best available appropriate technologiesd i l t h ith th t "and in complete harmony with the nature."

Solar Cooling

• Vapour Absorption Chiller (VAC) refrigeration system that canachie e cooling p to 6 0Cachieve cooling up to 6 0C

• Scheffler dishes allow water to reach temperature of 180 0C ‐Corresponding steam at 8 to 10 kg/cm2 pressurep g g/ p

• 100 Tr of cooling out of this solar Air Conditioning System usingScheffler Concentrators

Solar Crematorium

• World's First and only “Solar Crematorium”y

• System to be backed by biogas for buffer supply

Renewable heaven

• MSA is using solar street lamp, cooker, and many otherrenewablesrenewables

• Sustainability at Ashram has got the human dimension as well!

Summary

• Biogas: Versatile and efficient• Biogas: Versatile and efficient

• R&D: Improvement of efficiency and environmental performance of biogas production and utilization

F Bi d l t l t l li i i l• For Biogas development, clear governmental policies are crucial

• Integration and compensation of biogas – technically, financially and socially

• Trees can be retained

• Biogas is a quick, easily controlled fuel

• No smoke or smell (unless there is a leak)

• Clean pots

• Sludge is a better fertilizer than manure or synthetic fertilizers (and

is cheaper than manufactured products)is cheaper than manufactured products)

• Reduced pathogen transmission compared to untreated waste

Q&A

Commonsense is the realised sense of proportion!
