BioPolymers Trends

Current progress on Bio-Based Polymers and their future trends: a reference review paper
Biobased Polymers Trends

Upstream of bioplastics, if you are interested in understanding the processes that allow to turn plants into building blocks of plant based chemistry then bio –polymers and bioplastics, I encourage you to read the excellent review paper published by Babu, O’Connor and Seeram in 2013 and edited by SpecialChem on Aug 12,2013.

This is just an extract of the introduction. It highlights what is referred to as the transition between the first generation of plant based chemistry, using the edible part of the plant such as corn and wheat sugars, and the second generation, using non feedstock ligno-cellulosic biomass.

“The first generation of bio-based polymers focused on deriving polymers from agricultural feedstocks such as corn, potatoes, and other carbohydrate feedstocks. However, the focus has shifted in recent years due to a desire to move away from food-based resources and significant breakthroughs in biotechnology.

Bio-based polymers similar to conventional polymers are produced by bacterial fermentation processes by synthesizing the building blocks (monomers) from renewable resources, including lignocellulosic biomass (starch and cellulose), fatty acids, and organic waste.

Natural bio-based polymers are the other class of bio-based polymers which are found naturally, such as proteins, nucleic acids, and polysaccharides (collagen, chitosan, etc.).

These bio-based polymers have shown enormous growth in recent years in terms of technological developments and their commercial applications.

There are three principal ways to produce bio-based polymers using renewable resources:

  • Using natural bio-based polymers with partial modification to meet the requirements (e.g., starch)
  • Producing bio-based monomers by fermentation/conventional chemistry followed by polymerization (e.g., polylactic acid, polybutylene succinate, and polyethylene)
  • Producing bio-based polymers directly by bacteria (e.g., polyhydroxyalkanoates).

In this paper, an overview of bio-based polymers made from renewable resources and natural polymers derived from plant and animal origins is presented.

The review will focus on the preparation, properties, applications, and future trends for bio-based polymers.

This paper discusses the use of renewable resources such as ligno-cellulosic biomass to create monomers and polymers that can replace petroleum-based polymers, such as polyester, polylactic acids, and other natural bio-based polymers, which are presented in (see image at the top).

  1. Science is fascinating and the recent developments for polymers and monomers are quite interesting. In fact, I just learned that some polymers are being used in the skincare industry and GMP monomers are now being used to manufacture tools more efficiently.
