liquid whey. In an article found on Science Daily, researchers have discovered a way to possibly turn this waste into biofuel or feedstock additives. By using microbes to to break down the leftover fructose molecules into two more useful compounds such as caproic acid and caprylic acid. Being able to break down this waste material means a better source of additives for feedstock of animals in the place of antibiotics.
This article interested me because I eat a lot of greek yogurt but did not know how much waste was actually created. With researchers looking for new ways to turn waste into something useful there would be very little actual waste as the majority of the compounds needed to create greek yogurt have a purpose, whether it is to be put into the yogurt itself or to be sent elsewhere as another compound to be added to another formula.
