Sorbitol-Based Biodegradable Plastics from Rubberized Cassava Starch and Tofu Dregs Starch
Not relevant to microplastics — this study develops biodegradable plastic from cassava starch and tofu dregs with sorbitol as a plasticizer, focused on creating a petroleum-free alternative material rather than addressing microplastic contamination.
Microbial Production of Biopolymer Polyhydroxybutyrate (PHB): Current Challenges and its Application
This review examines the microbial production of polyhydroxybutyrate (PHB), a biodegradable polyester produced by microorganisms as an energy and carbon storage compound, covering current production challenges and industrial applications. The study discusses PHB as a biopolymer alternative to petroleum-based plastics, addressing cost, yield, and scalability barriers limiting its commercial adoption.
