s ory Hyderabad Milk Requirement 25 Laks /Day. Currently

Supply 14-15 Laks/day, milk coming from outside AndhraPradesh

Established in Nov. 2009. 21 Acre Farm - 2 Acres Dairy.Invested over 4 Cr. $800,000 (Land,Animals, Sheds,Pasturization Equipment Office and Infrastructure)

Over 300 buffalos and cows 26 full time staff - reside onfarm. Produce over Buffalo 1500.

Milk sold to over 6 Major Hotels in City, Retail Customer Base

of 150 +

Current Cost of milk Rs 35-50/Liter and increasing

Distribution 3000 ltrs/per day

Hrs per day major power cuts in India

Milk Processing plant (Paneer, Yogurt, Skim Milk,Ghee) Use heat from wood fired boiler for pasturization

C30 Generates electricity Supplements Boilerwith hot water. Output 30 65 C saves

approximately 50 Kg of wood per day Decrease use of wood convert fully to biogas in

2012 by increasing animals

COST COMPARISON

Cost of Wood Fired Boiler/Diesel Generator Combination is $ 394,600.

1000 Liters/hr pasteurization plant with a wood fired boiler and Dis Gen set. Wood fired boiler

costs $4500Fuel ($500/mo $6000/Yr). A 30 Kw dis gen. set ($12,000 - it consumes 7

liter/hr $28/day (10,080/yr). Assume the pasteurization plant would operate 3-4 hrs per day.

Over 20 years cost : life span of the diesel generator and wood fired boiler are approximately7-10 years ($16,500 X 2 = $33,000). (Diesel 20 yrs X $10,080 = $201,600, wood 20 yrs X

$6,000 = $120,000). Maintenance is $ 2000/yr = $ 40,000. Total cost is $ $394,600.

Cost of Digester and Capstone C30 Micro-turbine is $ 207,000

The Capstone C30 Micro turbine and digester cost is approximately (Capstone - $61,000, Gas

cleaning equip - $10,000, Digester - $15,000,). The C30 - 26 Kw of electricity and exhaust

heat is used for pasteurization milk to temperature of 85C.

Over 20 years costs: life span of the Micro turbine is 10 yrs (2 X 61,000 = $ 122,000).

Digester life is 30 years ($ 15,000). Maintenance $ 3000/yr = $ 60,000. This total is $ 207,000.

SUMMARY Dairy 300 cows - C30 micro turbine 4-6 hours - 45-m3 (1,589-ft3) digester.

Methane 25 times more potent than CO2 and remains in atmosphere upto 15 years.

Assume 41 days of operation. Approximately 10,785 m3 of CH4 emitted into

atmosphere - burned to generate electricity and heat. 10,785- m3 will produceapproximately 19.4 tonnes of CO2 with a Global Warming Potential (GWP) of

19.

Heat recovery for water inlet temperature of 30C and flow rate of 1.5 l/s to 50-

85C possible under low flow conditions.

Dairy project effective way of controlling climate change. The more that the

microturbines run, more CH4 to electricity/heat.

This is a winwin situation for cost and environment
