Structure Indian Biogas Association Biogas an introduction Biogas potential and present scenario Biogas: A need for Indian urban, rural and Industrial sector Socio economic model of Biogas Challenges for Biogas Casestudy study : Muni SevaAshram
Indian Biogas Association The association was founded in 2011 and is now mushrooming. The sole motto of the association iti is propagating Biogas in a sustainable way. www.biogas india.com
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 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, kitchen waste Silage from agricultural crops g g p as Napier grass, Sugar beet, Sugar cane, Maize
Modularisation
Modular Biogas plant in Germany Ca 45 000 m3 biogas/day Ca. 45,000 m3 biogas/day, Liquid fertilizer storage capacity ca. 48,000 m3
Organic fertilizer 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 hectares Chemical fertilizer consumption in India: 16,122,580 metric tons, which could be reduced by the use of organic fertlizer If you think organic food is expensive, have you priced cancer lately? Joel Salatin, founder of Polyace farms Rates for organic fertilizer can be veryfied between 2500 7000 INR for 70% TDS www.biogas india.com

Utilization of Biogas BIOGAS Drying, Desulfurization Gas conditioning with or without CO2 separation Compression Reformation (possibly) Boiler CHP Bottling or gas grid Filling station Fuel cell Heat Electricity & Heat Substitute for LPG or nature gas Fuel Electricity and heat www.biogas india.com
Financial Analysis 1.8 2.1 Units of Electricity INR 14.7 @ INR 7/KWh* 1 Ncum of Biogas 0.4 Kg of Compressed Biogas INR 20 @ INR 50/Kg* INR 5 @ INR 5/NCum * CAPEX & OPEX almost similar for both type of plants Not to forget Biofertilizer is an intrinsic part of revenue for Biogas business!
Biofuels in Comparison
Scenario Scattered 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
Challenges Finance Energy management Technical O&M Challenges Social engineering Policy Cost www.biogas india.com

Gobar Bank Concept
Project Uniqueness Bhitbhudrakmodel 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 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 hygiene Providing smoke free atmosphere into kitchen Providing cleaner environment in to village Women empowerment

Muni Seva Ashram: A Case Study
Geographical location MSA 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. 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 society, without regards to cast, creed, religion or financial status of the recipient, employing the best available appropriate technologies and incomplete lt harmony with thenature." t
Solar Cooling Vapour Absorption Chiller (VAC) refrigeration system that can achievee cooling up to 6 0 C Scheffler dishes allow water to reach temperature of 180 0 C Corresponding steam at 8 to 10 kg/cm 2 pressure 100 Tr of cooling out of this solar Air Conditioning System using Scheffler Concentrators
Solar Crematorium World's First and only Solar Crematorium System to be backed by biogas for buffer supply
Renewable heaven MSA is using solar street lamp, cooker, and many other renewables Sustainability at Ashram has got the human dimension as well!
Summary Biogas: Versatile and efficient R&D: Improvement of efficiency and environmental performance of biogas production and utilization For Biogas development, clear governmental policies i 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) Reduced pathogen transmission compared to untreated waste
