More than 10 years have passed since the first edition of this volume was published in 2010. During this period, there have been considerable scientific advancements and technological developments of PLA. PLA continues to captivate the interests of technologists and researchers, as reflected by the sustained increase in the number of publications related to PLA (Figure P.1). The main goal for the second edition is to update the volume with new progress made on various topics of PLA. We made a minor change in the book title, adding “End of Life” to it given the expanded discussions related to this area.
FIGURE P.1 Number of publications since 1984 based on Web of Science search (accessed on 24 September 2021) using the keywords (“polylactide,” “poly(lactic acid),”, and “polylactic acid.”
For completeness and better flow, we deliberately allowed some overlap between chapters so that they are relatively stand‐alone. Chapter 1 is a reprint from the first edition. Chapter 9 is a reprint from Chapter 10 of the first edition. Since the theoretical framework of rheology for PLA remains valid, we have decided to include this chapter in the present edition. In addition, a part of Chapter 20, “Spinning of poly(lactic acid) fibers,” from the first edition is now incorporated in Chapter 13 of the present edition.
We are grateful to all authors who contributed their manuscripts and thankful to them for entrusting us to edit their contributions to meet the needs of this volume. It would not have been possible to complete this project without their participation and patience during the preparation of this book. We hope that readers will find this updated edition of the book useful. We are looking forward to receiving comments and feedback regarding the content of this book.
