State of art review on sustainable biodegradable polymers with a market overview for sustainability packaging

One of the economic sectors with the fastest growth rates is the packaging business. Nearly 60% of plastics are burned, returning the thermal energy but adding to the CO 2 footprint even if CE solutions are being promoted. This increased emission not only has a detrimental impact on climate change, but also has poor sustainability indicators that lag behind market trends. In these environments, the packaging sector is essential to the effective execution of responsibilities and the fulfillment of evolving consumer demands. To satisfy consumer and industry demands, new packaging methods are being developed. Environmental awareness, changes in consumer lifestyles, and the development of new fields of information (such as nanotechnology or biotechnology) are driving forces behind the growth of smart packages that can encompass food shelf-life while maintaining and monitoring their safety and eminence while also protecting the environment. Over the past few decades, the packaging industry has greatly grown the variety of plastic-based packaging systems and designs. Plastics are permeable systems that allow the flow of low molecular weight substances, such as gases and vapors, between the inside and outer atmosphere, in contrast to more conventional packaging materials like glass and metals. Despite this drawback, they are still quite desirable in various packaging industries due to their wide range of manufacturing options, simplicity of handling and processing, low cost, excellent chemical resistance, etc. The global market for biodegradable plastic would be valued at USD 4.1 billion. During the projection period, it is expected to grow at a compound annual growth rate (CAGR) of 9.7%. The packaging industry is anticipated to expand by over 3% year between 2018 and 2028, reaching approximately $ 1.2 trillion (Four key trends such as Economic and demographic growth, Sustainability, Consumer Trends and Brand owner trends that will outline the forthcoming of packaging to 2028, 2021). Understanding the mechanics of mass transfer in polymers has thus been the focus of extensive corporate and academic study to facilitate the development of materials with enhanced barrier qualities.
