Converting Glycerol
to Higher Value
Products
As biodiesel production increases in response to federal and
state tax credits and mandates, more and more glycerol (a by-
product of biodiesel production) will be produced as well.
While glycerol (also known as glycerin) is a useful product
for the food and pharmaceutical industries, the glycerol that
results from biodiesel production is "crude" because it is
