Abstract

Lignocellulosic biomass-based plastics provide a sustainable alternative to petroleum-based plastics by converting agricultural by-products into value-added materials, promoting a circular economy. This study investigates the development of thermoplastics from sugar beet pulp (SBP), a by-product rich in cellulose and pectin. A one-pot direct transesterification process was used to fully substitute hydroxy groups in SBP with acyl chains of varying lengths (C2-C10), achieving up to 96 % substitution. The thermal and mechanical properties of SBP esters were analyzed without fractionating polysaccharides. SBP esters exhibited excellent melt flow properties, making them suitable for injection molding applications. The presence of pectin influenced the thermal behavior of the materials; the removal of pectin increased the flow temperature from 155.7 to 204.6 °C. These findings highlight the potential of SBP esters as sustainable plastics, offering a pathway to convert agricultural by-products into high-value materials, thus contributing to a circular economy.

期刊介绍： Carbohydrate Polymers stands as a prominent journal in the glycoscience field, dedicated to exploring and harnessing the potential of polysaccharides with applications spanning bioenergy, bioplastics, biomaterials, biorefining, chemistry, drug delivery, food, health, nanotechnology, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, tissue engineering, wood, and various aspects of glycoscience. The journal emphasizes the central role of well-characterized carbohydrate polymers, highlighting their significance as the primary focus rather than a peripheral topic. Each paper must prominently feature at least one named carbohydrate polymer, evident in both citation and title, with a commitment to innovative research that advances scientific knowledge.
