“…Thermoplastic starches (TPS) are the type of starch that is thermally and/or mechanically plasticized to substitute the use of synthetic polymers [68]. TPS is a promising material in biopolymer composites due to its availability, renewability, recyclability, and thermoplastic behavior [69].…”

In spite of the fact that a prodigious portion of petroleum covers multitudinous products in the commercial world, its nonbiodegradable characteristic is an unenviable factor. The utilization of biodegradable polymers or biopolymers is a prominent alternative to petroleum-based plastic products. Reinforcing natural fibers to biopolymer matrices significantly improves the properties of prepared plastic products. Such biopolymer composites have been developed by researchers to provide environmentally responsible materials and thereby reduce carbon footprint. Modification or functionalization of natural fibers is important to ameliorate the interfacial bonding with biopolymers, and to successfully obtain high-performance composite materials that can compete with conventional petrochemical-based polymer composite counterparts. Another widely accepted composite development technique is by combining different types of fibers into a single matrix to develop highly valued hybrid composites. The review focuses on the extraction, processing and characterization of bio-based materials; natural fibers and biopolymers, and their synergistic application and future scope as biopolymer composites in automotive and other growing sectors.

“…The improvement of bioplastics based on acetylated starch is due to the replacement of hydrophilic groups by acetyl, which results in a less flexible and hydroscopic bioplastic. Recent studies reported the effect of different acetylation on the starch-based bioplastic properties [ 90 , 91 ].…”

“…It is important to observe that the same proportion of PCL and native starch, disintegration was complete. Nevoralová et al [ 90 ] demonstrated that the biodegradation of starch acetate-based bioplastics can be monitored by starch DS. In a composting system, starch-based bioplastics with high DS resulted in a lower mineralization rate than starches with low or moderate DS.…”

Advantages and Disadvantages of Bioplastics Production from Starch and Lignocellulosic Components

The accumulation of plastic wastes in different environments has become a topic of major concern over the past decades; therefore, technologies and strategies aimed at mitigating the environmental impacts of petroleum products have gained worldwide relevance. In this scenario, the production of bioplastics mainly from polysaccharides such as starch is a growing strategy and a field of intense research. The use of plasticizers, the preparation of blends, and the reinforcement of bioplastics with lignocellulosic components have shown promising and environmentally safe alternatives for overcoming the limitations of bioplastics, mainly due to the availability, biodegradability, and biocompatibility of such resources. This review addresses the production of bioplastics composed of polysaccharides from plant biomass and its advantages and disadvantages.

“…The deacetylation process, in turn, can be studied by quantifying the average degree of substitution (DS), defined as the average number of acetyl substituent groups per anhydroglucose unit (AGU) in the CA molecular structure [23]. For this purpose, a saponification reaction followed by titration of the unreacted NaOH with an acid is a standard recommendation [24][25][26]. The quantification of the CA saponification product by ion chromatography [17] and additional derivatisation methods, involving the aminolysis of CA followed by gas chromatography-mass spectrometry analysis [20], have also demonstrated promising performance for quantifying DS.…”
