This comprehensive guide navigates the complex issues of energy and productive efficiency in polymer processing. Readers will understand how the pursuit of energy efficiency leads to productive efficiency, and how the benefits in productivity usually outweigh the benefits from energy savings. They will also learn how managing by energy cost centers not only facilitates a company's energy management but can also be a highly effective model for business management. They will discover the crucial role of methodological adherence for successful implementation of energy and productive management systems, and how the quest for corporate energy and productive efficiency creates competitive companies with a greater opportunity to achieve a prosperous future, rather than one risking their continuity. From foundational energy concepts in industry to in-depth analyses of consumption patterns, the book introduces Monitoring and Targeting methodologies and innovative approaches like the Energy Gap Method. It explores strategies to bridge identified energy gaps, offering practical insights. Real-world case studies showcase successful applications of these methods. The book culminates in a forward-looking exploration of digitalization and artificial intelligence as tools to revolutionize polymer processing, making it an essential resource for professionals, researchers, and students seeking practical knowledge in energy optimization.
