Non-biodegradable biopolymers from renewable resources: perspectives and impacts

Area of Science:

• Biotechnology and Materials Science

Background:

• The focus of biopolymer production has been on biodegradable alternatives to fossil-derived plastics.
• Biodegradable polymers like polyhydroxyalkanoates and polylactic acid substitute polyolefins.
• The production of non-biodegradable polymers from renewable resources is underexplored.

Purpose of the Study:

• To investigate the potential of biotechnologically producing non-biodegradable polymers from renewable resources.
• To highlight the significance of polythioesters as a novel class of non-biodegradable biopolymers.
• To address the dual need for both biodegradable and non-biodegradable polymers from sustainable sources.

Main Methods:

• Review of current trends in biopolymer production.
• Introduction of polythioesters as a new class of bacterial-derived polymers.
• Discussion of the persistence of polythioesters against microbial degradation.

Main Results:

• Polythioesters are produced by bacteria but are resistant to microbial degradation.
• This challenges the conventional paradigm that naturally derived compounds are biodegradable.
• Identified a gap in the market for non-biodegradable polymers from renewable feedstocks.

Conclusions:

• Biotechnological production of non-biodegradable polymers from renewable resources is feasible and valuable.
• Polythioesters represent a promising class of materials meeting this need.
• Further research into sustainable production methods for both biodegradable and non-biodegradable polymers is warranted.
