Whey
Production
• Hard cheese83% of milk converted into sweet whey
• White cheese60% of milk converted into permeate whey
Recovery
• Recovered whey is only 4%.
• Remaining discharge in the city sewer.
Effluents
• 183,000m3 factory effluents.
• BOD(2300ppm),COD(4,050ppm),TSS(540ppm), TDS(2290ppm),
oil/grease(420ppm)

4. CP opportunity Assessment
• CP for pollution prevention.
• CP, a cost effective approach.

5. CP Techniques
Implemented
Results
Whey has
higher
nutritional
value than
molasses
Whey is
safe to use
in certain
conditions
Experimental Phase:
•Chemical, physical, nutritional,
values of whey is assessed.
•The storage life of whey is
assessed.
Pilot phase:
•Safety of using whey as animal
feed is verified.
•Value of whey in terms of
growth rate and weight gain is
assessed.
•The feasibility of the process
is assessed.
Technically acceptable & safe
Weight gain as almost same as
in case of molasses feeding.
Highest yield efficiency (kg
feed/kg weight gain)

6. Cost benefit Analysis
Factory
Outcome
Recovery of more than
6,000 tons of byproducts
Elimination of
environmentally polluted
water
Elimination of capital cost
needed in end-of-pipe
treatment
25% reduction in
wastewater disposal
Farms’
Outcome
Input material change
100% saving in water
consumption
75% saving in dry feed
consumption
Increase in safety factor of
feed
Provision of economic &
convenient supplements
