“…On the other hand, cassava starch and flour can be directly converted to TPS by plasticization using the existing technologies and machines, e.g., extruders [26,[33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] and internal mixers [51][52][53][54], which are commonly used for conventional plastics. TPS has been produced not only from native cassava starch but also from modified cassava starches [32,39,47,[49][50][51]55,56].…”

Population growth and urbanization in Thailand has generated negative environmental externalities and the underuse of agricultural materials. Plastics from cassava present an alternative that helps reduce the use of non-biodegradable petroleum-based plastics and can reshape a sustainable cassava value chain. The objectives of this study are to evaluate the cassava value chain, consumer acceptance, and the opportunities and challenges for developing bioplastics from cassava in Thailand. We analyze the value added to different applications of cassava products and investigate the consumer acceptance of bioplastic from cassava using a two-step cluster analysis. From an economic perspective, bioplastics based on cassava add a value of 14.8–22 times that of cassava roots. We conducted a survey of 915 respondents and found that consumer acceptance of bioplastic products from cassava accounts for 48.6% of all respondents, but few are willing to pay extra for them. We also found that the development of cassava-based bioplastic not only positively contributes to economic aspects but also generates beneficial long-term impacts on social and environmental aspects. Considering cassava supply, bioplastic production, and potential consumer acceptance, the development of bioplastics from cassava in Thailand faces several barriers and is growing slowly, but is needed to drive the sustainable cassava value chain. This study provides guidelines for businesses and the government to adopt bioplastics from cassava.

“…The authors rationalized the overall enhancement in mechanical properties based on the improved dispersion of TPS phase, as well as the ability of ZSM5 to reinforce the micro-mechanical properties of the blend. However, the authors also pointed out that further increased loadings of ZSM5 above 5 wt % ended up reducing the tensile strength of the compatibilized blend due to the aggregation of ZSM5 particles at the interface [92]. …”

Compatibilized Immiscible Polymer Blends for Gas Separations

Membrane-based gas separation has attracted a great deal of attention recently due to the requirement for high purity gasses in industrial applications like fuel cells, and because of environment concerns, such as global warming. The current methods of cryogenic distillation and pressure swing adsorption are energy intensive and costly. Therefore, polymer membranes have emerged as a less energy intensive and cost effective candidate to separate gas mixtures. However, the use of polymeric membranes has a drawback known as the permeability-selectivity tradeoff. Many approaches have been used to overcome this limitation including the use of polymer blends. Polymer blending technology synergistically combines the favorable properties of different polymers like high gas permeability and high selectivity, which are difficult to attain with a single polymer. During polymer mixing, polymers tend to uncontrollably phase separate due to unfavorable thermodynamics, which limits the number of completely miscible polymer combinations for gas separations. Therefore, compatibilizers are used to control the phase separation and to obtain stable membrane morphologies, while improving the mechanical properties. In this review, we focus on immiscible polymer blends and the use of compatibilizers for gas separation applications.

“…However, starch lacks strength and cannot be a moisture barrier for packaging applications. Thus, starch-based packaging material is frequently blended with higher-strength and hydrophobic polymers − or used to form bilayer films through deposition on other types of polymers such as chitosan …”

This work developed bilayer and multilayer films from sodium alginate (SA) and starch (St) and systematically investigated their properties (thickness, moisture content, morphology, transparency, chemical interaction, film adhesion, tensile behavior, thermal transition, heat sealability, and gas permeability) to determine the potential use for flexible packaging. The SA/St bilayer and SA/St/St multilayer films were successfully developed by solution casting using layer-by-layer deposition and film drying on a hot plate. The SA/St and SA/St/St films were transparent and heat sealable. The interfacial fusion, adhesion, and hydrogen bonding between the SA and St layers promoted the mechanical properties (tensile strength, Young's modulus, and elongation at break) of the SA/St and SA/St/St films. The presence of SA layer enhanced the strength and rigidity of the starch film, while that of the starch layer improved the flexibility and heat sealability of the SA film. The seal strength increased with the thickness of the starch layer and the sealing temperature. The optimum seal strength was obtained from the SA/St/St films when heat sealed at 140−160 °C. In addition, the presence of SA layer provided the film structural integrity, preventing the deformation of starch layer during heat sealing. The obtained films had an excellent oxygen barrier. Thus, the SA/St and SA/St/St films could be promising alternatives for the oxygen barrier and single-use flexible packaging.
