Cleaner Production Technique by Zainab Amjad
- 1. Recovery of Cheese Whey for Use as an Animal Feed Presented by: Zainab Amjad
- 2. Raw Milk Ghee Hard cheese Whey White cheese Process Description *Misr Company for Dairy and Food *Animal Wealth Society Farm
- 3. Waste Analysis Waste from Factory Product Losses Wash Water Whey Sweet Whey Permeate Whey Whey Production • Hard cheese83% of milk converted into sweet whey • White cheese60% 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. Recovery of Whey at Factory Generate extra Revenue Use of Whey as Animal feed Conservation of Natural Resources Economic Benefits to the Farm
- 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
