Even when degraded, plastic never truly leaves the environment but is present as smaller pieces invisible to the naked eye (microplastics) that are choking marine life and propagating up the food chain Reduce, reuse and recycle have been embraced as the common approach to combat the escalating plastic waste problem.
The dream is to create a circular plastic economy where products are 100% recyclable, used for as long as possible, and their waste is minimised.
Because of environmental friendliness, renewable materials and suitable for packaging to substitute polymers made from petroleum.
However, poly(lactic acid) limitations are brittleness, low impact strength and low elongation at break restrict the applications.
Volume 1 has a total of 14 chapters and 2 sections: Section I Basic degradation study and phenomenon (6 chapters), and Section II Biomedical and environmental applications (8 chapters).
Volume 2 has also 14 chapters, and focuses on newly designed biodegradable polymers, and their formulation into different physical forms.These 2 volume books contain a compilation of new developments in the creation and use of biodegradable polymers including the relatively new polymers designed from the ground up (i.e., designing new monomers), the modification of existing biodegradable polymers to achieve particular new goals and functions, new fabrication methods for better efficiency, purity and yields, new engineering methods to formulate existing biodegradable polymers into new physical forms, and new applications of existing or new biodegradable polymers in biomedical and environmental arenas.These 2 volume books contain a total of 28 chapters grouped under 2 volumes.For packaging application, In addition to the need for environmental friendly materials, antibacterial packaging that can against bacteria is also desirable.For the safety of consumer’s health from bacterium, which causes diarrhea and foodborne illness.The chapters in both volumes have both new original articles and information and review articles with updated and new information. Oliveira, IPC –Institute for Polymers and Composites, Department of Polymer Engineering, University of Minho, Guimarães, Portugal) II.Although the bulk of the chapters in this book ( 90%) deal with issues in biomedical fields which are far more challenging, demanding, and costly to resolve, two chapters deal with use of biodegradable materials for environmental impacts.

Chu, Ezra Pharmaceutical, Inc., New York, USA) Chapter 10 Development of Polyester-Drug Nanoconjugates for Cancer Targeting and Treatment (Qian Yin, Rong Tong, Hua Wang and Jianjun Cheng, Department of Materials Science and Engineering, University of Illinois at Urbana-Champaign, Urbana, IL, USA) Chapter 11 Polycaprolactone Scaffolds for Stem Cell Research and Tissue Engineering (Guixin Shi, Hugh Q.These 2 volume books strive to provide to our readers the most up-to-date core information available in the published literature as well as our yet to be published studies with ample illustrations (total 416) on biodegradable polymers.Much of the information used in this book is from the authors’ own research activities over the past several decades.There are many examples of biodegradable polymers, some are produced from plants, animals or micro-organisms, others are purely synthetic (man-made).The most commonly known synthetic biodegradable polymers are polylactide (PLA), polyglycolide (PGA), polycaprolactone (PCL), polyhydroxyalkanoates (PHA), poly(butylene succinate) (PBS) and poly(butylene adipate-co-terephthalate) (PBAT)PLA is considered the most promising candidate to replace current plastics.
