Introduction

Protein-based biopolymers are natural polymers derived from the proteins of plants, animals, and microorganisms. They have excellent biocompatibility, biodegradability, and processability properties and are suitable for use in a wide variety of applications.

Historical Development:

Protein-based plastics were first developed in the early 20th century by notable inventors such as Henry Ford and George Washington Carver. Propelled by a theoretically revolutionary concept, those materials proved unsuccessful in the marketplace due to their dominant role in petrochemical feedstock production. In recent years however, there has been growing interest in bio-renewable and biodegradable materials due to environmental concerns and increased demand for sustainable alternatives to traditional plastics. To this end, novel materials have been developed and characterized, many of which are now readily available in the marketplace.

Source and Availability

PBB can be sourced from abundant and benign materials, often derived from agricultural and industrial waste. This makes them cost-effective and readily available for production.

Advantages of Protein-based Plastics

Protein-based plastics are reported to be eco-friendly polymers of great potential where the unique properties of proteins can be used to provide additional functionality when compared to other polymers, and to this end they have shown great potential for a sustainable environment. It is considered a biodegradable solution to many environmental challenges.
