Introduction

The global surge in plastic consumption, particularly in packaging, has led to severe environmental challenges due to the persistence of conventional petroleum-based plastics in natural ecosystems. These plastics often accumulate in landfills, oceans, and soils, causing pollution and posing risks to wildlife and human health. In response, the development of biodegradable polymers from renewable monomers has gained significant traction as a sustainable alternative for packaging applications. This approach offers the dual benefit of reducing reliance on fossil resources and ensuring environmentally friendly end-of-life disposal [1].

Packaging accounts for a substantial portion of plastic use globally, especially single-use items like food wrappers, bags, and containers. Conventional plastics such as polyethylene (PE), polypropylene (PP), and polystyrene (PS) are resistant to microbial degradation, persisting for hundreds of years. Biodegradable polymers, by contrast, are designed to break down under natural environmental conditions, converting into harmless products such as carbon dioxide, water, and biomass. This feature is critical for reducing landfill burden and marine pollution [2].

Biodegradable polymers can be synthesized from renewable monomers derived from biomass such as sugars, vegetable oils, starch, cellulose, and amino acids. Common renewable monomers include lactic acid, caprolactone, itaconic acid, and furans. These monomers are produced through fermentation or chemical transformation of plant-based feedstocks, offering a carbon-neutral or even carbon-negative footprint compared to petrochemical routes [3].

Designing biodegradable polymers for packaging requires balancing mechanical strength, barrier properties, processability, and biodegradability. Packaging materials must protect contents from moisture, oxygen, and contaminants, while being strong enough for handling and transport. Tailoring polymer molecular weight, crystallinity, and copolymer composition helps optimize these properties. For example, copolymerization of lactic acid with glycolic acid can modulate PLA’s brittleness and degradation rate [4].

Synthesis of biodegradable polymers involves methods such as polycondensation, ring-opening polymerization, and microbial fermentation. Ring-opening polymerization is widely used for monomers like lactide (for PLA) and caprolactone. Advances in catalyst development—both metal-based and organocatalysts—have improved polymerization control, enabling high molecular weight polymers with desirable architectures such as block copolymers and graft polymers [5].

Conclusion

The design and synthesis of biodegradable polymers from renewable monomers present a compelling pathway toward sustainable packaging solutions. By leveraging renewable resources and green chemistry, these materials offer the potential to reduce plastic pollution and fossil fuel dependency significantly. While challenges remain, continued research, policy support, and consumer awareness will accelerate the transition to biodegradable packaging—helping to create a circular economy in the plastics sector.
