Synthesis of cost-effective and biodegradable multifunctional bioplastic film from the plant gum and poly(hydroxyalkanoates) and its application as packaging material as well an adsorbent-cum-antimicrobial properties.
The proposed research work focuses on designing a new low-cost, green and biodegradable multifunctional bioplastic film with improved performance by inclusion of some active components having adsorbent-cum-antimicrobial properties from Moringa oleifera gum (MOG) and poly(hydroxyalkanoates) (PHAs) to combat two frontline global issues of economic and environmental concern. It has been reviewed that the most of the use of the MOG and its modified forms had been restricted mainly to the medical field. However, some studies reported the use of the modified MOG in removal of dyes and heavy metal ions. Thus, there is scanty information where MOG is used as adsorbent, yet there is no single report in the literature wherein MOG has been developed as bioplastic film with antimicrobial and adsorbent properties. Further, polyhydroxyalkanoates (PHAs), natural biopolymers are well known for their resemblance with the synthetic plastics. However, use of these biopolymers is associated with number of shortcomings such as high cost, low rate of swelling due to its hydrophobicity, low flexibility, low melt viscosity, low decomposition temperature, and poor mechanical and barrier properties. These shortcomings can be improved by their blending or grafting with polysaccharides from low cost renewable resources such as plant gum. Thus, MOG and PHB are selected as candidate materials for the proposed research work. Till date, no other research work on blending and grafting of plant gums with PHAs has been reported so far. This ground-breaking idea of using plant gum, here, is not only cost-effective on account of the utilization of a renewable resource; it also possesses adsorbent-cum-antimicrobial properties which expand its utility in various fields. Thus, the proposed research project will adopt a new approach of using cost-effective renewable resource to synthesize bioplastics to realise twin objectives of economic and environmental i.e., e2 concept.
