ABSTRACT
Biodegradable polymers are divided into petroleumbased biodegradable polymers (P/b-p) and microorganism-based biodegradable polymers. Production of P/b-p involves the emission of greenhouse gases, and the bioactivity of microorganisms is utilized to synthesize monomers from plant products, which are further used to synthesize polymers. Poly(lactic acid) (PLA) is an aliphatic polyester made up of lactic acid building blocks. PLA is a polymer made from renewable sources and has the potential to reduce the dependency on conventional plastics made from fossil-based resources. Growing attention to PLA is interrelated to some distinctiveness that is deficient in other polymers, specifically concerning renewability, biocompatibility, processability, and energy saving. The wide usage of polymeric materials in engineering is largely due to their valuable mechanical properties.
