Green Chemical Engineering (GCE) is much more than a method for addressing environmental problems. It offers a framework for achieving innovation. Time and again, companies looking to the future through the lens of green chemical engineering have enjoyed tremendous environmental and economic returns. GCE is a way to not only improve the environment but also positively impact the client's bottom line. Avoiding the generation of waste (including energy) or pollutants can often be more cost-effective than controlling or disposing of pollutants once formed. Sustainable development is often used synonymously, but is more of an economic term describing how our economy should improve, and implying that an increase in quantity is not necessarily the goal, but rather an increase in quality . Pollution prevention incorporates the concepts of source reduction and recycling. Source reduction is defined as those multimedia activities that prevent waste generation and contaminant release. Recycling, for the purposes of pollution prevention, is defined as a process in which a waste material is reused in the original manufacturing process or another process.
