Polyhydroxyalkanoates from Fruit Wastes; A Sustainable Panacea for Plastic Crisis!

Abstract

“White pollution” which is defined as the solid waste generated through the consumption of different types of plastic products, has been identified as a significant global environmental issue threatening the natural environment, human health, and economies with regard to pollution. Plastics are chemically inert, preventing unnecessary gas and moisture exchange with the surroundings.

Food packaging is an application where plastics are extensively used, as it significantly reduces the possibility of microbial contamination while retaining food quality. Moreover, it is lighter, possesses high specific strength, and is tear resistant. Plastics can be produced colorless or transparent if necessary, allowing the consumer to view food products through the packaging. It can also be easily moulded to fit the shape of the food item it is holding without affecting its performance requirements. Its stiffness and increased strength ratio make it desirable to be used as food containers and cutlery in rigid food ware applications.
