The goal of this presentation is to forge a pathway for environmental sustainability by incorporating basic principles and concepts of green chemistry, green engineering, recycle, reuse, and recovery; and zero discharge. Bearing in mind, the design and implementation of completely green products and processes is an enormous challenge. Because the number of chemical synthesis pathways is enormous, there is no one systematic, fail-safe method for ensuring that the chemistry being implemented is green. Indeed, it is more nearly correct to inquire if a proposed chemical manufacturing process is simply “greener” than other alternatives. Thus, green chemistry recognizes the importance of incremental improvements applying a set of 12 principles to define and guide the scope of green chemistry. Sustainable engineering involves the design, commercialization, and use of processes and products that are feasible and economical while minimizing both the generation of pollution at the source and the risk to human health and the environment. The discipline embraces the concept that decisions to protect human health and the environment can have the greatest impact and cost effectiveness when applied early in the “design and development phase of a process or product.” Sustainable engineering transforms existing engineering disciplines and practices to those that promote environmental sustainability. A few mini-case studies are presented.
