Biopolymers are referred to as polymeric substances which occur in living organisms. It comes as a surprise that biopolymers are in no way new to this world. It is primarily due to our fascination with petrochemical products that these amazing materials have been overlooked for such a long time. However, today we face a different challenge. Environmental challenges are pushing away from synthetic or petro-chemically formulated products, whereas economic factors are pulling back from usually more costly "green" alternatives. This book introduces two characteristics of biopolymers; potential products and their few important applications elucidating the present significance of biopolymers.
