“…2,5-Furandicarboxylic acid (FDCA)-based polyesters have attracted considerable attention. − For instance, poly(ethylene furandicarboxylate) (PEF) is a competitive alternative to poly(ethylene terephthalate). − Bio-based poly(pentamethylene furanoate) displayed unexpected and surprising properties due to its special two-dimensional microstructure . In most cases, improving thermal and mechanical properties, in turn, harms the degradability of polyesters.…”

The 2,5-furandicarboxylic acid (FDCA)-based aliphatic−aromatic copolyester is an intensively researched area of bio-based polymers with high gas barrier and mechanical properties. However, the contradiction between the barrier and degradation performance still remains a huge challenge and severely limits their applications. Here, we combine branched neopentyl glycol, hydrophilic diglycolic acid, and FDCA to prepare poly-(neopentyl glycol diglycolate/furandicarboxylate) (PNDF) copolyesters. With poor crystallization capability, PNDF40 and 50 (content of NF units) display low modulus (58 vs 108 MPa) but elastomeric behavior. Their tensile broken samples can even rapidly restore the original length, which might be derived from the physical crosslinking networks. It was interesting to find that even when more than 50% of the NF units were replaced by ND units, the PNDF copolyesters still retained high gas barrier. The introduction of diglycolic acid improved the hydrolysis rate, showing potential degradability under environmental conditions. However, enzymatic degradation using Candida antarctica lipase B (CALB) revealed that the branched neopentyl glycol decreased the biodegradation rate when compared with other linear diols. Furthermore, the hydrolytic pathway of PNDF was explored by density functional theory (DFT) calculation. Through Fukui function analysis, we identified the most active sites of PNDF for hydrolysis. Additionally, the calculated energy barrier indicated that hydrolysis of the polymer chain became easier with the increase in the number of ND units. Molecular dynamics (MD) simulations of PNDF−CALB illustrated that Val154 and Gln157 of CALB located at catalytic entrance formed noncovalent interaction with PNDF, which would sterically hinder the carbonyl carbon from reaching an ideal distance for nucleophilic attack and decrease the tendency to enter a pre-reaction state.

“…Due to the same synthetic precursors of rhamnolipids and PHA, many microorganisms capable of converting PET into PHA also have the potential to synthesize rhamnolipids [144]. The conversion of PET into biodegradable plastics is a clean and cost-effective way to generate a great market in PET recycling [146].…”

Polyethylene terephthalate (PET) is a widely used plastic that is polymerized by terephthalic acid (TPA) and ethylene glycol (EG). In recent years, PET biodegradation and bioconversion have become important in solving environmental plastic pollution. More and more PET hydrolases have been discovered and modified, which mainly act on and degrade the ester bond of PET. The monomers, TPA and EG, can be further utilized by microorganisms, entering the tricarboxylic acid cycle (TCA cycle) or being converted into high value chemicals, and finally realizing the biodegradation and bioconversion of PET. Based on synthetic biology and metabolic engineering strategies, this review summarizes the current advances in the modified PET hydrolases, engineered microbial chassis in degrading PET, bioconversion pathways of PET monomers, and artificial microbial consortia in PET biodegradation and bioconversion. Artificial microbial consortium provides novel ideas for the biodegradation and bioconversion of PET or other complex polymers. It is helpful to realize the one-step bioconversion of PET into high value chemicals.

“…FDCA is currently used as a building block material for the production of PEF, which is a fully bio-based plastic with excellent thermal properties and superior barrier properties, compared to conventional PET [77,78]. Furthermore, PEF is considered to be an ideal substitute for the current polymer used in packaging [79].…”

Achievement of some of the United Nation’s Sustainable Development Goals will not be possible if global trends in pollution associated with petrochemical-based plastics continue. Alternatives to petrochemical plastics have been researched intensely, but they have not been developed to replace current plastic products in a commercially viable way. The demand for single-use plastic personal protective equipment created by the COVID-19 pandemic has stimulated urgency in developing pollution prevention strategies that transcend reliance on highly variable consumer behavior. Biological material plastics are potentially sustainable because their manufacture utilizes renewable resources, and they are biodegradable. In this paper, challenges facing the sustainable management of discarded single-use petrochemical plastics are discussed, and a material lifecycle perspective is proposed that would be integrated into a circular economy of biological plastics. Preventing petrochemical plastics pollution requires a shift to fossil-free feedstock and energy and the design of biopolymers with desired properties. In this work, strategies for improving the performance and recyclability of biological plastics by designing polymers with diversified functionalities are presented.
