Plastics are everywhere. Bags, bank cards, bottles, and even
boats can all be made of this celebrated but much-maligned
material. Yet most of us know next to nothing about plastics. We do
know that they are practical and cheap--but they also represent a
huge environmental problem, for they literally take ages to
decompose. In this engaging book, E.S. Stevens tells us everything
we have always wondered about plastics and of the efforts, in
America, Europe, and Asia, to develop a new breed of
environmentally friendly plastics. He points to a possible future
where plastics will no longer be made of petroleum, but of
plants.
The first two chapters assess the increased use of plastics as a
relatively new alternative to other materials. The third chapter
introduces us to their impact on the environment and strategies for
their disposal or recycling. The next two chapters cover basic
concepts and terms used in polymer sciences and provide some basic
chemistry. With these fundamentals in tow, the author compares how
petroleum-based and biological polymers are made, and the various
ways in which they decompose. He acquaints readers with the
emerging technologies, their commercial viability, and their
future. Finally, instructions are given for preparing basic
bioplastics using readily available materials.
Nonspecialists will find "Green Plastics" a concise introduction
to this exciting interdisciplinary topic--an introduction otherwise
not available. For students it provides easy entry to an area of
science with wide appeal and current importance; for teachers,
excellent background reading for courses in various sciences. The
prospect of depleted fossil fuel supplies, and the potential
benefits of bioplastics to the environment and to rural areas that
could supply the raw materials, make this book a compelling
presentation of a subject whose time has come.
