Microplastics and biobased polymers to combat plastics waste

Area of Science:

• Environmental Science
• Materials Science
• Toxicology

Background:

• Microplastics (MPs) are a pervasive global pollutant with documented adverse effects on ecosystems, human health, and hygiene.
• The chemical complexity and toxicological impacts of MPs necessitate advanced detection and quantification methods.
• Persistent plastic pollution presents a significant environmental challenge, driving the search for sustainable alternatives.

Purpose of the Study:

• To review current chemical methods for real-time quantification and identification of microplastics in environmental and biological samples.
• To summarize the detrimental health effects associated with human exposure to microplastics.
• To explore the potential of biopolymers as environmentally friendly alternatives to conventional plastics.

Main Methods:

• Literature review of analytical techniques for microplastic detection and quantification.
• Synthesis and analysis of research on the toxicological impacts of microplastic exposure.
• Examination of advancements in the preparation and modification of various biobased polymers.

Main Results:

• Established methods for chemical quantification and identification of microplastics are crucial for assessing their environmental burden.
• Microplastic exposure is linked to numerous toxic impacts on human well-being.
• Significant progress has been made in developing and modifying biobased polymers such as polylactic acid (PLA), poly(ε-caprolactone) (PCL), lignin-based polymers, poly-3-hydroxybutyrate (PHB), and poly(hydroxyalkanoates) (PHA).

Conclusions:

• Biopolymers offer a promising avenue for mitigating the environmental impact of plastic pollution.
• Further research and development in biobased polymers are essential for addressing challenges in plastic waste management.
• Effective strategies for microplastic detection and the adoption of sustainable biopolymer alternatives are key to environmental protection.
