General Concepts in Sustainable Chemical Processes

Abstract

This chapter introduces the general and basic concepts used in subsequent chapters relating to specific topics in sustainable chemical processing for the future. Sustainable chemical processes and technologies are defined and the following concepts introduced: the triple bottom line; the 12 principles of both green chemistry and green engineering; the hierarchy of waste management used as a sustainable design tool; and life cycle assessment. Finally, two common process approaches that lead to sustainable chemical processes are outlined: the use of continuous or flow processes; and process intensification. These concepts are then contextualised in terms of the structure of this book.
