Sustainable Additives in Polymer Technology covers both the fundamentals and advanced information about various aspects of bio-based additives for different polymers and their numerous applications, providing practical guidance to researchers and industry professionals on how to select, rank, formulate and apply bio-based additives in polymer manufacturing processes. The book starts with a general overview of each bio-based additive and its role in polymer industry, along with their mechanisms of action based on their defined functions. In Part II, industrial and research developments are discussed, as well as classification of materials' family, their loading level, main advantages over their usage, challenging aspects, and mechanism of performance. Finally, Part III focuses on the economy and commercial grades for each family of bio-based additives, followed by a discussion on research directions and future development in Part IV.
