Bio-Polyethylene and Polyethylene Biocomposites: An Alternative toward a Sustainable Future.

Area of Science:

• Polymer Science
• Materials Science
• Biotechnology

Background:

• Polyethylene (PE) is a widely used, non-biodegradable plastic posing waste management challenges.
• Bio-based polyethylene (bio-PE), derived from renewable resources, presents an eco-friendly alternative.
• Growing environmental concerns and regulations are driving the expansion of bio-PE production and markets.

Purpose of the Study:

• To review various production methods for bio-PE.
• To examine the development and potential applications of PE and bio-PE biocomposites using agricultural waste.
• To elucidate advancements in the degradation of PE and its biocomposites to assess environmental impacts.

Main Methods:

• Review of literature on bio-PE production techniques (fermentation, gasification, catalytic conversion).
• Analysis of studies on creating biocomposites with agricultural waste fillers (corn, abaca fibers) in PE and bio-PE matrices.
• Examination of research on abiotic and biotic degradation mechanisms for PE and biocomposites.

Main Results:

• Bio-PE production is increasing due to environmental pressures.
• Biocomposites with approximately 50% agricultural fiber content achieved high Young's moduli (4.61-5.81 GPa).
• Potential applications identified in automotive, construction, and furniture industries.

Conclusions:

• PE and bio-PE biocomposites offer sustainable material solutions.
• Further research into production, application, and degradation is crucial for widespread adoption.
• These materials contribute to a circular economy and a more sustainable future.
