![]() ![]() Physical, thermal, rheological, and mechanical properties of both polymers as well as their permeability and migration properties have been reviewed. This paper represents an overview of the feasibility of both Poly Lactic Acid (PLA) and polyhydroxyalkanoates (PHAs) as alternative materials that can replace petroleum-based polymers in a wide range of industrial applications. Therefore, bio-based polymers are moving towards becoming the favorable option to be utilized in polymer manufacturing, food packaging, and medical applications. Concerns about preservation of natural resources and climate change are considered worldwide motivations for academic and industrial researchers to reduce the consumption and dependence on fossil fuel. The increase in the level of carbon dioxide due to the combustion of fossil fuel is causing global warming. Furthermore, oil is often subjected to price fluctuations and will eventually be depleted. The present utilization of natural resources cannot be sustained forever. ![]() Recently, the public awareness of the negative effects of petroleum-based plastics on the environment has increased. In spite of the fact that petroleum-based plastics are convenient in terms of fulfilling the performance requirements of many applications, they contribute significantly to a number of ecological and environmental problems. ![]()
