Glycerin is a colorless, odorless, liquid which is the main
molecule of fats known as triglycerides. Triglycerides occur
naturally in vegetable oils, animal fat and in humans, while
many industrial manufacturing processes produce large quantities
of glycerin as a by-product. Our glycerin conforms to USP and IP
standards. Where does glycerin come from? Today, glycerin is
primarily produced as a by-product during various manufacturing
processes such as soap-making and biodiesel production. Glycerin
as a by-product is an impure form called crude glycerin, which
is generally 80 percent pure. Crude glycerin can be sold as a
stand-alone product or refined into a pure product called
refined glycerin, which is generally 98% pure. The process of
refining glycerin involves removing water, odors and other
undesirable organic matter. Aemetis produces crude glycerin as
by-product of biodiesel production and refines crude glycerin at
our plant in Kakinada, India where we also produce edible oils.
