retail news in context, analysis with attitude

Greek yogurt has been getting a lot of good press in recent years, and has turned into a major industry, generating $2 billion a year in sales and growing.

But now, apparently, there is a downside to Greek yogurt production - a byproduct of its being made is something called "acid whey."

USA Today writes that this "nasty" liquid waste byproduct "can't be dumped, because it would prove too toxic to the environment, ruining waterways and killing fish." And so some farmers, scientists and yogurt manufacturers are looking for options.

"One scientist wants to extract the small amount of protein to use in infant formula," the paper writes. "Other scientists believe they can extract the sugar to be used in other foodstuffs. And one farmer is converting the lactose into electricity generating methane."

There is a fiscal necessity here - New York State, which has become a major producer of Greek yogurt and has used the industry as a tool to generate economic recovery, alone generated 66 million gallons of acid whey just in 2011.
KC's View:
hope they figure this out. Because I love my Chobani Lowfat banana Greek Yogurt, but I hate the idea that maybe I'm eating a product the manufacturer of which may be bad for the environment. Because at the end of the day, it is really all about me, and whether I feel guilty eating something...

(Actually, a lot of people may feel this way. Knowing that acid whey is a toxic byproduct of something we enjoy may make that item just a little bit less enjoyable...)
