Unconventional Starch Sources for Sustainable Bioplastics, CRC, Ghent, Belgium , ss.61-74, 2026
Today, one of the biggest problems of humanity is to achieve sustainable development without harming the environment. Climate change and sustainable development are important issues that stand out in this context. Packaging materials can have a huge impact on the environment. It is important that packaging processes are carried out using natural resources to a minimum and that the environmental impact of the products is reduced when they are finished. Additionally, packaging materials must be easily disposed of, processed using conventional methods, and recyclable. However, a packaging material that can meet these ideal properties has not yet been discovered. Therefore, there is increasing interest in solving this problem. Types of biobased polymers available on the market include starch-based, polylactic acid-based, and cellulose-based materials. Different plant sources are widely used in the synthesis of bioplastics because these sources require easier maintenance compared to animal and microbial alternatives. These plant sources offer viable and sustainable alternatives that can replace synthetic polymer-based plastics in various applications, such as food packaging. Cereal crops such as rice, corn, and tuber plant resources such as potatoes are frequently used in bioplastic production because these products are of low cost, easily accessible, and abundant. Starch, which is abundant in plants, is considered a powerful source in bioplastic synthesis due to its affordable cost and thermoplastic properties. In recent years, many studies have been conducted on the use of bulbs of Allium cepa L., tubers of Nelumbo nucifera Gaertn. (Lotus) and Xanthosoma sagittifolium (L.) Schott (Taro), and rhizomes of Glycyrrhiza glabra L., Zingiber officinale Roscoe, and Maranta arundinacea L. for this purpose. In the not-too-distant future, when cooking vegetables, their packages may be washed, chopped, and roasted in oil instead of onions. In this study, the roots of G. glabra L., Ficus benjamina L., and Cissus quadrangularis L. have been elaborated as polymer sources, while the tubers of Ipomoea batatas (L.) Lam., Solanum tuberosum L., and Dioscorea alata L. have been identified as polymer sources and bulbs of A. cepa also have been studied as polymer sources.
