Valorization of Lignocellulose by Producing Polyhydroxyalkanoates under Circular Bioeconomy Premises: Facts and Challenges

ACS Sustainable Chemistry & Engineering, Journal Year: 2022, Volume and Issue: 10(50), P. 16459 - 16475

Published: Dec. 5, 2022

In light of the current concerns about environmental issues caused by excessive use fossil resources, more emphasis has been paid to transition a sustainable and circular economy. Bioplastics as eco-friendly products originating from biomass wastes have gained much attention solve problem plastic pollution. Among them, polyhydroxyalkanoates (PHAs) are microbial polyesters produced using various feedstocks─renewable or recycled waste materials─contributing commercial life cycle being part bioeconomy. However, scale-up PHA process cost effectively sustainably remains challenging for large-scale industrial applications. This perspective provides comprehensive overview insights into lignocellulosic biomass's role in achieving Emerging greener conversion technologies discussed characterize energy demand, cost, sustainability within biorefinery production. addition, recent advances synthetic biology fermentation processes production discussed. Technological challenges, i.e., bioreactor setup, downstream operation, inconsistent properties improve PHAs help transfer this technology real-world applications, also addressed.

Chemical Upcycling of Poly(3-hydroxybutyrate) into Bicyclic Ether–Ester Monomers toward Value-Added, Degradable, and Recyclable Poly(ether ester)

ACS Sustainable Chemistry & Engineering, Journal Year: 2022, Volume and Issue: 10(25), P. 8228 - 8238

The chemical recycling of plastic wastes into value-added products is an attractive strategy to reduce the consumption fossil fuels and pollution. We report here facile upcycling poly(3-hydroxybutyrate) (P3HB) polymerizable monomers subsequent polymerization toward degradable recyclable polymers. bicyclic monomer 4-methyloctahydro-2H-benzo[b][1,4]dioxepin-2-one (4-MOHB) was first synthesized from P3HB through efficient steps. obtained underwent bulk ring-opening (ROP) catalyzed by stannous octoate (Sn(Oct)2) give amorphous materials. With benzyl alcohol (BnOH) as initiator, Sn(Oct)2 can effectively catalyze ROP ether–ester in a controllable fashion. Moreover, poly(4-methyloctahydro-2H-benzo[b][1,4]dioxepin-2-one) (P(4-MOHB)) showed closed-loop recovery property due fused structure. selective depolymerization P(4-MOHB) homopolymer back 4-MOHB be easily realized using p-toluenesulfonic acid (TsOH) or catalyst solution bulk. This recycle bioplastics materials has promising application prospect beneficial extend life cycle environment-friendly

Elastomeric vitrimers from designer polyhydroxyalkanoates with recyclability and biodegradability

Science Advances, Journal Year: 2023, Volume and Issue: 9(47)

Published: Nov. 22, 2023

Cross-linked elastomers are stretchable materials that typically not recyclable or biodegradable. Medium-chain-length polyhydroxyalkanoates (mcl-PHAs) soft and ductile, making these bio-based polymers good candidates for biodegradable elastomers. Elasticity is commonly imparted by a cross-linked network structure, covalent adaptable networks have emerged as solution to prepare thermosets via triggered rearrangement of dynamic bonds. Here, we develop chemically installing the within biologically produced mcl-PHAs. Specifically, an engineered strain Pseudomonas putida was used produce mcl-PHAs containing pendent terminal alkenes chemical handles postfunctionalization. Thiol-ene chemistry incorporate boronic ester (BE) cross-links, resulting in PHA-based vitrimers. with BE at low density (<6 mole %) affords soft, elastomeric material demonstrates thermal reprocessability, biodegradability, denetworking end life. The mechanical properties show potential applications including adhesives robotics electronics.
