Sustainability metrics

Professional engineering organisations are developing ideas in this held - for example see the publication from the Institution of Chemical Engineers The Sustainability Metrics (Sustainable Development Progress Metrics - recommended for use in the process industries) May 2002.

There are a vast number of quaternary ammonium compounds or quaternaries (1). Many are naturally occurring and have been found to be cmcial in biochemical reactions necessary for sustaining life. A wide range of quaternaries are also produced synthetically and are commercially available. Over 204,000 metric tons of quaternary ammonium compounds are produced aimuaHy in the United States (2). These have many diverse appHcations. Most are eventually formulated and make their way to the marketplace to be sold in consumer products. AppHcations range from cosmetics (qv) to hair preparations (qv) to clothes softeners, sanitizers for eating utensils, and asphalt emulsions.
