Description
Handbook of Bioplastics and Biocomposites Engineering Applications The 2nd edition of this successful Handbook explores the extensive and growing applications made with bioplastics and biocomposites for the packaging, automotive, biomedical, and construction industries.
Bioplastics are materials that are being researched as a possible replacement for petroleum-based traditional plastics to make them more environmentally friendly. They are made from renewable resources and may be naturally recycled through biological processes, conserving natural resources and reducing CO2 emissions.
The 30 chapters in the Handbook of Bioplastics and Biocomposites Engineering Applications discuss a wide range of technologies and classifications concerned with bioplastics and biocomposites with their applications in various paradigms including the engineering segment. Chapters cover the biobased materials; recycling of bioplastics; biocomposites modeling; various biomedical and engineering-based applications including optical devices, smart materials, cosmetics, drug delivery, clinical, electrochemical, industrial, flame retardant, sports, packaging, disposables, and biomass. The different approaches to sustainability are also treated.
Audience
The Handbook will be of central interest to engineers, scientists, and researchers who are working in the fields of bioplastics, biocomposites, biomaterials for biomedical engineering, biochemistry, and materials science. The book will also be of great importance to engineers in many industries including automotive, biomedical, construction, and food packaging.
