The Biology in Green Chemistry
Yeast, bacteria, enzymes, proteins… may not be what immediately come to mind with the phrase Green Chemistry. But of the 93 teams that have won Presidential Green Chemistry Awards, 31 had technology that hinged on the use of biological processes or biobased inputs, point out the folks at the Biotechnology Industry Association.
BIO has created a cheat sheet of sorts on the various bio-powered technologies behind past award winners, complete with summary blurbs and links to fuller descriptions. And it opens with the famous
Twelve Steps, er, Twelve Principles of Green chemistry.
One of my favorites is the 1999 discovery by researchers at Dow AgroSciences of Spinosad, a selective insecticide derived from a soil microbe. It is a very relevant organic pesticide used today. The fun detail, not in the blurb, is that the microbe was found in the environs of a rum distillery. Why a scientist was looking there, in the dirt, is a fun question.
And more recently, a 2013 award went to Richard P. Wool of the University of Delaware who “has created several high-performance materials, such as adhesives and foams, using biobased feedstocks, including vegetable oils, chicken feathers, and flax.” These materials sound not-quite good enough to eat, but certainly quite good enough to sit on.
