Chemists are trained to create new molecular compounds in a lab, where they work under fume hoods wearing goggles and gloves to protect themselves from their potentially toxic concoctions. When the experiments are successful, explains Laura Wright Treadway in OnEarth, the chemist often files a molecular patent and the new compound can be used to make consumer products: items like cleaning solvents, baby wipes, water purifiers, lipsticks, television sets, flame retardants, and, of course, all things plastic, from water bottles to rubber duckies to intravenous tubing.
One solution to this devil-may-care approach is green chemistry: the science of creating sustainable compounds that reduce or eliminate toxic substances while also taking into consideration a product’s entire life cycle. Green chemists ask commonsense questions: Will car mechanics be breathing it, as a brake-cleaning solvent, inside the poorly ventilated bowels of an auto shop? Will babies be stuffing it, as a plastic toy, in their mouths? Will everyone who washes clothes be scraping it, in the form of lint, out of their dryers?
