History
In May 2004, DuPont and Tate & Lyle announced that they would start up a joint venture to build a facility that produces polymers from renewable feedstock instead of petrochemicals. In particular, their goal was to design a fermentation system that converts corn sugar into PDO (propanediol manufactured in this way is referred to in the media as "BioPDO"). They argue that using such a bioprocess is more energy efficient than conventional petrochemical processes (conversion of propylene into propanediol) because the bioprocess has four advantages over the conventional process: smaller environmental footprint, lower operating costs, smaller capital investment, and greater sustainability due to use of renewable corn feedstock.

Famous quotes containing the word history:
“The history of persecution is a history of endeavors to cheat nature, to make water run up hill, to twist a rope of sand.”
—Ralph Waldo Emerson (1803–1882)
“If man is reduced to being nothing but a character in history, he has no other choice but to subside into the sound and fury of a completely irrational history or to endow history with the form of human reason.”
—Albert Camus (1913–1960)
“History has neither the venerableness of antiquity, nor the freshness of the modern. It does as if it would go to the beginning of things, which natural history might with reason assume to do; but consider the Universal History, and then tell us,—when did burdock and plantain sprout first?”
—Henry David Thoreau (1817–1862)
