Review On Polyhydroxybutyrate (phb) And Global Research Trends

Abstract

Polyhydroxybutyrate (PHB) Is One Of The Most Studied Members Of The Polyhydroxyalkanoate (PHA) Family. It Shows Promise As A Biodegradable And Sustainable Alternative To Traditional Plastics. With Rising Global Worries About Plastic Pollution, Microplastic Buildup, Climate Change, And Dwindling Fossil Resources, The Demand For Eco-friendly Polymers Has Jumped Significantly. PHB Has Become A Top Choice Due To Its Biodegradability, Biocompatibility, And Mechanical Properties That Are Similar To Polypropylene. This Review Looks At PHB Research Trends, Microbial Production Systems, Methods For Using Substrates, Techno-economic Assessments, Industrial Uses, And Environmental Benefits. It Also Includes Insights From Bibliometric Studies, Performance Of Microbial Strains, And The Impact Of Using Waste-derived Feedstocks To Lower Production Costs. While PHB Has Excellent Environmental Benefits, Issues Like High Production Costs, Substrate Prices, Complex Downstream Processing, And A Lack Of Large-scale Production Facilities Make Commercialization Difficult. This Paper Aims To Bring Together Existing Scientific Literature Into A Detailed Review For Academic And Industry Stakeholders, Offering Guidance For Future Advancements In PHB Research And The Development Of Sustainable Materials.
