Whey and Dry Milk Products as Feedstocks for Ethanol Production

摘要

Surplus whey and dry milk could have supplied about 1,383,723,000 lbs of lactose in 1978 for conversion to approximately 84,632,171 gallons of ethanol. This would be about .00085% of the total gasoline used in the US, or .0085% of the ethanol needed to produce a 10% ethanol/gasoline blend nationwide. To the extent that these are surpluses not desired for food purposes, whey and dry milk can contribute to ethanol supply in a small way. However, no energy or economic assessment has been made so the cost/benefit relationship is unknown. (ERA citation 05:006670)
