Abstract: | Process integration is a holistic approach to process design and operation. It emphasizes the unity of the process units
and objectives. Therefore, it provides a unique framework for integrating environmental issues with other process objectives
such as profitability, yield enhancement, debottlenecking and energy reduction. This paper presents a review of recent advances
in the area of pollution prevention through process integration. First, the alternative methods for industrial waste reduction
are discussed. Then, process integration is defined and categorized into three main components: synthesis, analysis and optimization.
Next, mass integration science and methods are reviewed with special emphasis on their critical role in pollution prevention.
Throughout the paper, various tools and techniques are described and illustrated.
