“…Hence, innovative research from biotechnology can aid in obtaining high cell biomass yield with high PHA output in large scale production. At the industrial scale, the polymers' physical, chemical, thermal and elasticity properties are important and can be achieved by genetic engineering and optimizing other important fermentation conditions [90]. Genetic modifications can control PHA composition; the monomer composition directly impacts on the physical and mechanical properties of the bioplastics after fermentation.…”

Global energy consumption has been increasing in tandem with economic growth motivating researchers to focus on renewable energy sources. Dark fermentative hydrogen synthesis utilizing various biomass resources is a promising, less costly, and less energy-intensive bioprocess relative to other biohydrogen production routes. The generated acidogenic dark fermentative effluent [e.g., volatile fatty acids (VFAs)] has potential as a reliable and sustainable carbon substrate for polyhydroxyalkanoate (PHA) synthesis. PHA, an important alternative to petrochemical based polymers has attracted interest recently, owing to its biodegradability and biocompatibility. This review illustrates methods for the conversion of acidogenic effluents (VFAs), such as acetate, butyrate, propionate, lactate, valerate, and mixtures of VFAs, into the value-added compound PHA. In addition, the review provides a comprehensive update on research progress of VFAs to PHA conversion and related enhancement techniques including optimization of operational parameters, fermentation strategies, and genetic engineering approaches. Finally, potential bottlenecks and future directions for the conversion of VFAs to PHA are outlined. This review offers insights to researchers on an integrated biorefinery route for sustainable and cost-effective bioplastics production.

“…Despite its relatively costly production cost, some common and important members of the PHA family, P(3HB) and P(3HB ‐co‐ 3HV), have been manufactured and commercialized (Mumtaz et al., 2010; Tian et al., 2009). In the industrial development of PHA, the polymer's structural, thermal, mechanical, and chemical properties (e.g., tensile strength, elongation, glass transition temperature, melting point, and elastic modulus) are mostly tailored to the desired applications by modifying the culture condition, feeding technique, substrate type, genetic makeup, and monomer composition (Joseph et al., 2020).…”

For many decades, global efforts have been attempted to replace the petrochemical plastics with biodegradable and environment friendly plastics. The petrochemical plastics that require many years to decompose have profound consequences on the environment. A natural, biodegradable, and plastic‐like polymer, polyhydroxyalkanoate (PHA), has been extracted from and synthesized by microbes, particularly bacteria. However, the prospective large‐scale production of PHA faced an economic bottleneck for less production costs. Research has thus shifted to one of the most common alternatives, which is the utilization of less costly raw materials or carbon sources that include industrial by‐products and wastes, such as glycerine pitch and glycerol. This review elucidates the discovery, basic mechanisms, and applications of PHA, as well as provides insights regarding the importance of PHA conversion from glycerine pitch and glycerol. This review also summarizes some possible future modifications to improve the efficiency of glycerine pitch and glycerol as carbon sources in PHA production. The conversion endeavors of wastes to a valuable product, PHA, that not only reduces petrochemical plastic pollution, waste generation, and PHA production costs but also supports economic and resource sustainability, which ultimately further progress towards the cradle‐to‐cradle design and circular bioeconomy concept.

“…The commonly used plastics in packaging materials include polyvinyl chloride, polyethylene terephthalate, polystyrene, polypropylene, and low‐density polyethylene (Sharma et al., 2020). However, these plastics are non‐biodegradable, thus giving rise to many environmental problems, including short‐ and long‐term pollution (Ashok et al., 2016; Joseph et al., 2020; Motelica et al., 2020; Sadeghi & Mahsa, 2015).…”

Plastic pollution is a significant concern nowadays due to wastes generated from non-biodegradable and non-renewable synthetic materials. In particular, most plastic food packaging material ends up in landfills, creating mass wastes that clog the drainage system and pollute the ocean. Thus, studies on various biopolymers have been promoted to replace synthetic polymers in food packaging and consequently, the high number of research in biopolymers food packaging, especially in the characterization, properties and also the development of the biopolymer. For biopolymer-based food packaging, silk fibroin (SF) has been highlighted because of its biodegradability and low water vapor permeability properties. This review focuses on the different properties of SF films prepared through solution casting and electrospinning for food packaging. Discussions encompassed chemical properties, mechanical properties, permeability, and biodegradability. This review also discussed the studies that used SF as the biomaterial for food packaging.
