“…The advancement and dissemination of PLA production and processing technology have caused its field of applications to expand significantly in recent decades, especially after the creation, in 2002, of the NatureWorks (USA) industrial large-scale PLA production plant, which currently operates with a production capacity of 150,000 metric tons/year [41,69,74,75]. The joint venture Total and Corbion (Amsterdam, The Netherlands) and Hisun (Wuhan, China) also produce PLA on a large scale, with a production capacity of 75,000 and 10,000 metric tons/year, respectively [41,42,69,75,76]. Other manufacturers produce PLA on a smaller scale and have been listed in the references [32,41,77].…”

“…Polymerization of the racemic mixture of lactic acid, rac-lactide (rac-LA) and mesolactide (m-LA) results in poly(D,L-lactic acid) or PDLLA, a random copolymer of D and L-lactic units, with an irregular and completely amorphous structure [71,75,90]. PDLLA has no T m but has a T g around 60 • C [32,87].…”

“…PDLLA has no T m but has a T g around 60 • C [32,87]. Due to its amorphous nature, PDLLA shows a faster degradation rate than stereoregular PLA, making it preferred for applications as a drug delivery vehicle and as a low-strength scaffolding material for tissue engineering [75,91]. PDLLA may show some crystallinity when synthesized by stereocontrolled ROP, through the action of a catalyst/initiator [32,80].…”

Poly(lactic acid) (PLA) is an important polymer that is based on renewable biomass resources. Because of environmental issues, more renewable sources for polymers synthesis have been sought for industrial purposes. In this sense, cheaper monomers should be used to facilitate better utilization of less valuable chemicals and therefore granting more sustainable processes. Some points are raised about the need to study the total degradability of any PLA, which may require specific composting conditions (e.g., temperature, type of microorganism, adequate humidity and aerobic environment). Polymerization processes to produce PLA are presented with an emphasis on D,L-lactic acid (or rac-lactide) as the reactant monomer. The syntheses involving homogeneous and heterogeneous catalytic processes to produce poly(D,L-Lactic acid) (PDLLA) are also addressed. Additionally, the production of blends, copolymers, and composites with PDLLA are also presented exemplifying different preparation methods. Some general applications of these materials mostly dedicated to the biomedical area over the last 10–15 years will be pointed out.

“…Among all biopolymers, PLA has the best attributes regarding its ecofriendly nature, such as low cost and high availability of the raw materials, low energy consumption during production, and biodegradability in both water and soil [22]. PLA can be used to coat the paper and paper boards to impart barrier properties [23]. Commercial PLA is amorphous in nature and has good optical transparency, making it suitable for packaging applications.…”

Research into alternative packaging materials is becoming more and more popular as a result of growing eco-friendly concerns regarding the usage of some petroleum-based polymeric packaging materials and coatings, as well as growing buyer demands for products with nutritious quality and extended shelf lives. Barrier coatings made of naturally renewable biopolymers can be applied to paper packing materials. These biopolymer coatings have the potential to replace the current synthetic paper and paperboard coatings, are strong oxygen and oil barriers, and may prevent the unintended moisture transfer in food goods. An appealing method of controlling the growth and spread of microorganisms in food packaging is the integration of antimicrobial compounds into coatings to create active/functional paper-based packaging materials. Here, in this review of the oxygen/moisture barrier, mechanical, and other characteristics of paper coated with bio-based materials. Examples are used to discuss the current and future uses of bio-based material coatings on paper packaging materials to improve barrier performance.

“…Since biopolymers such as polysaccharides are commonly produced as storage materials in living cells ( Gonzalez-Gutierrez et al, 2010 ), the biopolymers can be easily depolymerized by certain species of microorganisms such as fungi, yeasts, and bacteria ( Sirohi et al, 2020 ). Hitherto, several kinds of biodegradable plastics produced by microbial cells, including polyhydroxyalkanoates (PHA) ( Alves et al, 2022 ), poly(butylene adipate-co-terephthalate) ( Jian et al, 2020 ), and polylactic acid (PLA) ( Taib et al, 2022 ), have attracted extensive attention worldwide. Among all types of biopolymers, poly(3-hydroxybutyrate) (PHB) has attracted tremendous research attention in recent years due to its high biodegradability ( Getachew and Woldesenbet, 2016 ) as well as significantly lower energy requirement and CO 2 emission during the production process ( Lopez-Arenas et al, 2017 ).…”

In the context of a circular economy, bioplastic production using biodegradable materials such as poly(3-hydroxybutyrate) (PHB) has been proposed as a promising solution to fundamentally solve the disposal issue of plastic waste. PHB production techniques through fermentation of PHB-accumulating microbes such as Cupriavidus necator have been revolutionized over the past several years with the development of new strategies such as metabolic engineering. This review comprehensively summarizes the latest PHB production technologies via Cupriavidus necator fermentation. The mechanism of the biosynthesis pathway for PHB production was first assessed. PHB production efficiencies of common carbon sources, including food waste, lignocellulosic materials, glycerol, and carbon dioxide, were then summarized and critically analyzed. The key findings in enhancing strategies for PHB production in recent years, including pre-treatment methods, nutrient limitations, feeding optimization strategies, and metabolism engineering strategies, were summarized. Furthermore, technical challenges and future prospects of strategies for enhanced production efficiencies of PHB were also highlighted. Based on the overview of the current enhancing technologies, more pilot-scale and larger-scale tests are essential for future implementation of enhancing strategies in full-scale biogas plants. Critical analyses of various enhancing strategies would facilitate the establishment of more sustainable microbial fermentation systems for better waste management and greater efficiency of PHB production.
