The present book introduces the Composite Sustainability Indicator (CSI), defining sustainability as meeting present needs without compromising future generations. The CSI integrates the Waste Reduction Algorithm, risk assessment models, and energy intensity indices to evaluate environmental impacts and facilitate risk-informed design. Through case studies, the author demonstrates the effectiveness of these methodologies, aggregating them into a Key Process Indicator for sustainability analysis. The book covers chapters on computer-aided modelling, heterogeneous catalytic reactions, pollution prevention, and global warming. Notably, it delves into energy impacts, risk assessment methodologies, and the CSI's application in complex processes, such as refineries. Leveraging advanced process simulators like Aspen Plus and HYSYS, alongside WAR GUI, the author designs processes and estimates risks and environmental impacts. This guide aims to equip process systems engineers with tools to design environmentally conscious and sustainable chemical processes, using high-quality raw data endorsed by EPA. Strategic products, like sustainable gasoline blends, are studied as case studies.
