Today, the scientific community is facing crucial challenges in delivering a healthier world for future generations. Among these, quest circular and sustainable approaches plastic recycling one of most demanding several reasons. Indeed, massive use materials over last century has generated large amounts long-lasting waste, which, much time, not been object adequate recovery disposal politics. Most this waste by packaging materials. Nevertheless, decade, new trend imposed environmental concerns brought topic under magnifying glass, as testified increasing number related publications. Several methods have proposed polymeric based on chemical or mechanical methods.

Expanding Poly(lactic acid) (PLA) and Polyhydroxyalkanoates (PHAs) Applications: A Review on Modifications and Effects

Polymers, Journal Year: 2021, Volume and Issue: 13(23), P. 4271 - 4271

The high price of petroleum, overconsumption plastic products, recent climate change regulations, the lack landfill spaces in addition to ever-growing population are considered driving forces for introducing sustainable biodegradable solutions greener environment. Due harmful impact petroleum waste plastics on human health, environment and ecosystems, societies have been moving towards adoption natural based polymers whose conversion consumption environmentally friendly. Therefore, biobased such as poly(lactic acid) (PLA) polyhydroxyalkanoates (PHAs) gained a significant amount attention years. Nonetheless, some vital limitations broader use these biopolymers that they less flexible resistance when compared petroleum-based (e.g., polypropylene (PP), high-density polyethylene (HDPE) polystyrene (PS)). Recent advances shown with appropriate modification methods—plasticizers fillers, polymer blends nanocomposites, both can be overcome. This work is meant widen applicability by reviewing available materials methods their impacts focus mechanical properties. literature investigation leads conclusion PLA PHAs show strong candidacy expanding utilizations potentially substitute various applications, including but not limited to, food, active packaging, surgical implants, dental, drug delivery, biomedical well antistatic flame retardants applications.

Synthetic plastics have been reshaping the planet since early 20th century. They brought plenty of conveniences to our lives; meanwhile, plastic wastes discarded into environment are resistant biodegradation, accumulating in soil, water, and even organisms. Biodegradable polyester-based (BPPs), such as polylactic acid (PLA), poly(butylene adipate-co-terephthalate) (PBAT), succinate) (PBS), polycaprolactone (PCL), poly(β-hydroxybutyric acid) (PHB) considered be ecofriendly sustainable alternatives thrived rapidly past few decades. However, applications BPPs limited by their high prices compared conventional plastics, while blending with low-cost fillers has deemed a facile efficient solution foregoing issues. Technical lignin, class biodegradable aromatic polymers, extracted/isolated at large scale coproduct paper-making emerging lignocellulosic biorefinery industries. The economically competitive BPP composites reinforced lignin could not only facilitate valorization but also improve economic viability biorefinery. At present, key obstacle lies incompatibility between resulting from self-aggregation thermal condensation due its polyhydroxy structures. Herein, we overviewed series effective approaches promote interaction adding plasticizers blocking hydroxyl groups.

Published: Feb. 23, 2021

Using a simple esterification reaction of hydroxyl group with an anhydride group, pristine lignin was successfully converted to new (COOH-lignin) modified terminal carboxyl group. This chemical modification confirmed by the appearance absorption bands in FT-IR spectrum. Then, and COOH-lignin were incorporated into poly(lactic acid) (PLA) matrix typical melt-mixing process. When applied COOH-lignin, interfacial adhesion performance between filler PLA better stronger than lignin. Based on these results for COOH-lignin/PLA biocomposites, cost printing 3D filaments can be reduced without changing their thermal mechanical properties. Furthermore, potential as component biocomposites adequate demonstrated.
