Due to the rising worldwide demand for green chemicals, the bio-based polymer market is anticipated to expand substantially in the future. The synthesis of functional polymers has been a burgeoning area of research for decades. The primary driving force behind the development of bio-based polymers has been their compostability and biodegradability, which are critical given the public concern about waste. Significant advancements in the method for refining biomass raw materials towards the creation of bio-based construction materials and products are driving this rise. Bio-based polymers with this chemical structure are more flexible and adaptive, which allows them to attain their intended characteristics and functionalities. In commercial applications and healthcare and biotechnology, where completely manufactured, naturally occurring biomolecules are utilized and such polymers have the greatest impact. At the same time, limitations in polymer architectural control, biostability, and structural dynamics hinder the creation of biocompatible and functionally varied polymers. From this standpoint, the importance of functional biosynthetic polymers in the future years is highlighted, as well as new methods for addressing the aforementioned challenges. The article comprehensively highlighted the current strategies, market dynamics, and research trends of emerging Bio-Based Polymers. In addition, the most recent scientific breakthroughs in bio-based polymers are discussed.

“…It is produced through direct polycondensation of lactic acid or via ring opening polymerization of lactide [ 38 ] and can differ depending on the relative proportions of the two stereoisomers of lactic acid, which are D- and L-lactide [ 39 , 40 ]. PLA is one of the most successful biodegradable polymers since it is already employed for many different industrial applications, particularly for packaging and in biomedicine [ 7 ]. Given its brittle behaviour, it is often co-polymerized and blended with additives to improve its mechanical and physical properties [ 41 , 42 , 43 , 44 ].…”

Bioplastics have entered everyday life as a potential sustainable substitute for commodity plastics. However, still further progress should be made to clarify their degradation behavior under controlled and uncontrolled conditions. The wide array of biopolymers and commercial blends available make predicting the biodegradation degree and kinetics quite a complex issue that requires specific knowledge of the multiple factors affecting the degradation process. This paper summarizes the main scientific literature on anaerobic digestion of biodegradable plastics through a general bibliographic analysis and a more detailed discussion of specific results from relevant experimental studies. The critical analysis of literature data initially included 275 scientific references, which were then screened for duplication/pertinence/relevance. The screened references were analyzed to derive some general features of the research profile, trends, and evolution in the field of anaerobic biodegradation of bioplastics. The second stage of the analysis involved extracting detailed results about bioplastic degradability under anaerobic conditions by screening analytical and performance data on biodegradation performance for different types of bioplastic products and different anaerobic biodegradation conditions, with a particular emphasis on the most recent data. A critical overview of existing biopolymers is presented, along with their properties and degradation mechanisms and the operating parameters influencing/enhancing the degradation process under anaerobic conditions.

“…These green polymers, which range from small molecules to polymer materials to biomass, under appropriate active conditions after their intended use, represent one possible end-of-life solution. , As concerns about the environmental and biosafety impact of used polymers increase, there is sustained interest in the lifecycle of polymeric materials. A series of aliphatic polyesters, including poly(lactic acid) (PLA), − poly(glycolic acid), − poly(caprolactone), and polyhydroxybutyrate, − have been successfully developed as sustainable and degradable polymers. The introduction of an aromatic ring pendant into the backbone through the ring-opening polymerization (ROP) of mandelide , has produced a polyester as an alternative to nondegradable polystyrene.…”

Compared to fossil resources, which display limited degradability, exploring novel green polyesters as more sustainable alternatives is an extremely challenging task. In this study, we have developed an effective pathway from natural origin salicylic acid (SA) to poly(salicylic acid) (PSA) with high molecular weight. This was achieved by employing Lewis pair-mediated ring-opening polymerization of salicylic acid O-carboxyanhydrides (SAOCA). We identified two metal-free combinations, namely, 1,3-bis(2,6-diisopropylphenyl)imidazole (NHC-1)/N-[3,5-bis(trifluoromethyl)phenyl]-N′-cyclohexyl thiourea (TU-1) and 2-tertbutylimino-2-diethylamino-1,3-dimethyl-perhydro-1,3,2 diazaphosphorine (BEMP)/TU-1, that mediated ROP of SAOCA at room temperature within 100 min and successfully produced PSA with molecular weight greater than 150 kDa. We observed that the phase state of the polymerization solution switched from clarification to turbidity to phase separation when the PSA chain was growing up. Based on the NMR results of the interaction between organic base and TU-1, the analysis of polymerization kinetics, and DFT calculations, we found that the excess addition of TU-1 could effectively restrain unfavorable results in which very fast propagation of the polymerization chain caused phase separation in a short time. Furthermore, it improved the controllability of ROP reactions and the resulting chain length of PSA. The generality of this synthetic strategy was evaluated by the convenient preparation of other PSA-series polyesters via the ROP of SAOCA analogues varying the substituents. The obtained PSA-series polyesters exhibited good thermal stability and high glass transition temperature, outperforming some commodity polyolefins. This synthetic method paves the way for a better understanding of PSA-based polyesters as a class of future green materials applicable in the field of biomedicine and sustainable plastic packaging.
